Wholesale electricity prices ease as RES input increases

Wholesale electricity price levels are expected to drop to an average of 130 euros per MWh in the day-ahead market today, down 20 percent compared to yesterday, a de-escalation attributed to increased RES input, the energy exchange has informed.

Stronger winds have been forecast, increasing the generation potential of wind energy units.

The maximum price in the day-ahead market today is expected to reach 186 euros per MWh and the minimum price will be 92 euros per MWh.

Natural gas-fired power stations are scheduled to contribute the lion’s share, 40 percent, of the day’s electricity needs, renewable energy sources will contribute 24 percent, electricity imports and lignite-fired power stations will each provide 15 percent, while hydropower facilities will contribute 6 percent.

Electricity demand for the today is forecast to drop by 2.5 percent compared to yesterday.

 

 

Heatwave pushes up wholesale prices to over €100/MWh once again

The latest rise in temperatures, prompting further heatwave conditions around Greece, is impacting the wholesale electricity market as the average clearing price in the day-ahead market has risen again to levels of over 100 euros per MWh, following days of more subdued levels, according to energy exchange data.

The average clearing price for today is up to 103.8 euros per MWh, up from yesterday’s level of 93.47 euros per MWh and Sunday’s level of 75.34 euros per MWh.

According to the day-ahead market figures, overall electricity generation today is planned to reach 167,437,017 MWh, with lignite-fired power stations covering just 11,172 MWh, natural gas-fired power stations providing 86,541,739 MWh, hydropower facilities generating 11,829 MWh and all other RES units providing 57,894,278 MWh. Electricity imports are planned to reach 16,159,231 MWh.

Today’s electricity demand is expected to peak at 12.30pm, reaching 8,580 MW, according to data provided by IPTO, the power grid operator.

Three of power utility PPC’s lignite-fired power stations, Agios Dimitrios III, Megalopoli IV and Meliti, will be brought into action today, while five of the utility’s natural gas-fired power stations, Aliveri V, Lavrio IV and V, Komotini and Megalopoli V, will also be mobilized, along with gas-fired units operated by the independent players Heron, ENTHES, Elpedison (Thisvi), Protergia and Korinthos Power.

Wholesale ascent prompting hefty retail electricity price hikes

The activation, by electricity suppliers, of wholesale cost-related clauses included in their supply agreements is prompting significant retail increases, seen rising, compared to three months earlier, by 40 percent for the medium-voltage category and at least 33 percent for the low-voltage category.

Medium-voltage tariffs, previously at levels ranging between 64 and 65 euros per MWh, have reached 90 euros per MWh, a 40 percent increase, since the wholesale cost-related clauses were triggered by suppliers earlier this year, and are expected to rise further.

In the low-voltage category, concerning households, tariffs have increased from levels ranging between 70 and 90 euros per MWh, depending on the supplier and agreement, and will need to be raised to 120 euros per MWh for the recovery of increased wholesale costs.

Higher wholesale electricity prices have been attributed to a combination of factors, including higher CO2 emission right and natural gas prices, as well as a sharp rise in demand.

The situation is exacerbated during periods when RES output is subdued, prompting record-level price levels in the wholesale electricity market.

Last week, CO2 emission right prices set a new record of 58.25 euros per ton, up from 32 euros per ton in December, an 82 percent increase.

Natural gas prices have hit a 13-year high, TTF contracts reaching 29 euros per MW/h following levels of between 15 and 17 euros per MW/h in spring, a 93 percent increase. In June last year, gas prices had sunk to record-low levels of as low as 4.9 euros per MWh.

Last week, the average clearing price on the energy exchange ranged from 100.33 to 118.56 euros per MWh, up from 63.16 euros per MWh a month earlier.

In June, the average day-ahead market price on the energy exchange was 83.47 euros per MWh, more than double the level of 40.74 euros per MWh a year earlier.

Suppliers request revisions to alleviate cash-flow pressure

Electricity suppliers, facing steep and lasting wholesale electricity cost increases, which have resulted in cash-flow issues, are seeking revisions that could alleviate the pressure, in recommendations submitted to RAE, the Regulatory Authority for Energy.

Rising wholesale electricity costs have created major cash flow problems for non-vertically integrated electricity suppliers as they are being forced to pay increasing amounts for electricity and related guarantees ahead of payments, to them, by consumers.

Consumers have also felt the pinch as suppliers, seeking protection against the rising wholesale prices, have activated wholesale cost-related clauses incorporated into their supply agreements.

Solutions for both sides seem elusive at present as market forecasts do not see any price de-escalation ahead, only further increases.

In one of the recommendations forwarded to RAE, suppliers called for their cash collateral payments made to the Hellenic Energy Exchange, as a form of guarantee, to be replaced by letters of guarantee representing equivalent amounts.

Suppliers have also requested a reexamination of the clearing price and payment formula in the day-ahead and intraday markets.

They also requested extensions for surcharge payments to power grid operator IPTO and the distribution network operator DEDDIE/HEDNO.

 

Energy Exchange Group (EnEx) celebrates its 3-year anniversary

Founded in June 2018, EnEx is comprised of the Hellenic Energy Exchange S.A. (HEnEx) and the EnEx Clearing House S.A. (EnExClear). Since its designation by the Greek Regulatory Authority for Energy (RAE) as the Nominated Electricity Market Operator (NEMO), HEnEx has evolved in line with the European agenda for a single and integrated European energy market.

As a designated NEMO, HEnEx successfully performed the necessary market transformations for the preparedness and operation of the Greek power market under the new model. All changes were completed in time and by the 1st of November 2020, the Greek power market was integrated with the European Target Model for electricity markets. HEnEx now operates the Day-Ahead Market, the Intraday Market and an energy Derivatives Market.

A very important milestone for HEnEx was the market coupling of the Greek Day-Ahead market to the European markets – over the border between Greece and Italy on December 15th 2020. On May 11th 2021, HEnEx achieved its second market coupling with Bulgaria. These interconnections enable cross-border trading, optimal capacity allocation and congestion management – all of which, facilitate a European Union-wide market in electricity with optimal welfare and resource allocation.

EnExClear plays also an important role in the flawless operation of the spot electricity markets in Greece. It provides clearing, risk management and settlement services for the Day-Ahead Market and the Intraday Market, and is also responsible for the clearing, settlement and shipping of implicit cross border transactions with the coupled markets. Furthermore, EnExClear is also responsible for the risk management and the settlement of positions of the balancing market, which is run by the Greek Transmission System Operator (IPTO).

Both HEnEx and EnExClear are directing their efforts towards the next important steps:

The establishment of a gas trading platform is the next major milestone. In collaboration with the Greek Gas TSO (DESFA), RAE and the Ministry of Environment, EnEx is designing the model for the new gas trading platform which is expected to be operational in fall 2021.

This year, HEnEx will also start operating three Complementary Regional Intraday Auctions (CRIDAs) and foresees its inclusion in the European Cross-Border Intraday (XBID) initiative in Q1 2022. Furthermore, following the connection of the island of Crete to the mainland electricity network, HEnEx is also leading the integration of the island to the existing Day-Ahead and Intraday Markets of mainland Greece.

In this dynamic and evolving energy environment, EnEx is committed to contributing to sustainability and providing high quality, transparent and non-discriminatory services to its markets participants. With confidence, EnEx will continue developing with vision and determination, while learning from its positive experiences, and strengthening the relationship with its partners and stakeholders.

 

Greek-Italian-Slovenian intraday market coupling in autumn

Market coupling of the Greek, Italian and Slovenian intraday markets has been scheduled for September 21 through complementary regional intraday auctions (CRIDAs), a further step towards full unification of the European electricity market.

This market coupling move promises to bolster the liquidity of Greece’s intraday market, which has remained subdued since its launch several months ago, while also easing balancing market burdens of participants.

A liquidity boost in the intraday market is necessary for optimal management of intermittent production, as is the case with most RES units.

Greece’s coupling with Italy and Slovenia constitutes the first step in this direction, the intention being to avoid significant discrepancies for RES units and costs they cause.

The degree to which this coupling step will impact Greece’s intraday market remains to be seen, given the limited capacity of an existing subsea cable linking Greece and Italy, offering 500 MW.

This interconnection will require a capacity boost if high-level intraday market activity is to be achieved, as the infrastructure will need to be able to facilitate physical deliveries of electricity amounts ordered.

Also, the interconnection’s leftover capacity for intraday market trading will depend on the level of electricity import and export agreements established through the preceding day-ahead market.

For example, if, on certain days, the interconnection’s capacity is entirely taken up for day-ahead transactions, then intraday market trading will not be possible.

A second step in the coupling of Greece’s intraday market is planned with the country’s entry into the continual XBID (Cross Border Intraday) market with Italy and Bulgaria, planned for the first quarter of 2022.

Ministry committee set to deliver energy-storage framework plan

Facilities operating purely as energy storage stations will be placed under one category for licensing and regulatory purposes, while a separate category will be established for operations combining storage and RES stations, according to a proposal being prepared by a special committee assembled by the environment and energy ministry.

Also, all electricity markets, such as the day-ahead, intraday and balancing markets, will be open to all energy storage units, regardless of category, according to sources.

Units operating as energy storage stations, alone, are likely to receive licenses through an existing framework already used to grant licenses to natural gas-fired power stations, sources informed.

RAE has resorted to this existing framework as a solution to offer production licenses to a number of companies that have lodged applications for large-scale battery facilities.

The committee, set to stage its final session tomorrow, is expected to present a finalized proposal early next week to authorities, including political officials, RAE, the Regulatory Authority for Energy, energy market operators, and the energy exchange.

The energy ministry, placing great emphasis on energy storage as part of the country’s decarbonization strategy, intends to forward the committee’s framework plan for public consultation at the end of June. The ministry plans to submit a related draft bill to Parliament by October 31.

Medium-voltage suppliers seek higher-priced deal revisions

A sharp rise in medium-voltage energy costs over recent times, resulting from higher wholesale prices, threatens to damage the competitiveness of Greek manufacturers, Antonis Kontoleon, president of EVIKEN, the Association of Industrial Energy Consumers, has told energypress.

Rallying CO2 emission right prices as well as persistently higher prices in the day-ahead and balancing markets have prompted electricity suppliers to seek revised medium-voltage agreements as protection against loss-incurring sales.

Electricity suppliers, maintaining business to business agreements with medium-voltage consumers have increased – by 20 percent compared to just recently – their number of requests forwarded for new supply agreements.

More crucially, suppliers are asking their customers to accept upward price revisions.

In many cases, suppliers have forwarded letters to customers informing that they will no longer be able to service existing supply agreements unless prices per KWh are raised.

Low-voltage consumers also face increased electricity bill costs following the activation, by suppliers, of cost-protection clauses.

Independent suppliers have activated wholesale price-related clauses, incorporated in their supply agreements, while power utility PPC has triggered, for the first time, a CO2 emission rights cost-related clause.

RAE, the Regulatory Authority for Energy, has summoned PPC’s administration to offer an explanation on this decision, at a meeting today. The authority is also expected to soon summon independent suppliers.

Consumers returning to PPC, led by wholesale-linked hikes

Higher wholesale electricity prices, prompting independent suppliers to activate wholesale-cost clauses included in their supply agreements to avoid losses, are tightening up the market by leading disappointed consumers back to the power utility PPC, a clear regression in the effort to establish a broader, more competitive field of players, latest data has indicated.

Consumers opting to leave independent suppliers and return to PPC rose by 56 percent in the first quarter of 2021 compared to the equivalent period a year earlier, market data obtained by energypress has shown.

The number of consumers leaving independent suppliers for any other supplier increased by approximately 40 percent in the first quarter of 2020, the data showed.

This increase in consumer returns to PPC is expected to be reflected in forthcoming market-share data, market officials believe.

Last year, the wholesale market price, represented, at the time, as the system marginal price, ended April last year at 38.02 euros per MWh, whereas this year, in the form of the recently launched target model’s day-ahead market, the wholesale price in April has exceeded 63 euros per MWh.

Increased CO2 emission right costs and elevated TTF and Brent prices are factors that have driven wholesale electricity prices higher. So, too, are higher balancing costs, currently more than double levels of previous years.

Wholesale electricity prices for the next twelve months are seen averaging 89 euros per MWh in the low-voltage category and 79-80 euros per MWh in the medium-voltage category.

PPC, which has never achieved its commitment to lower its market share to less than 50 percent, is offering customers significant discounts at below cost, and, as a result, hampering the market liberalization process and further narrowing the profit margins of independent suppliers, a prominent market official has told energypress.

RAE, the Regulatory Authority for Energy, has the authority and responsibility to take action against suppliers selling electricity at  below cost and protect consumers against misleading offers, the official added.

Wholesale electricity cost up 8% in 1Q, surcharges double

The cost of wholesale electricity averaged 65.412 euros per MWh in the first quarter of 2021, up 8 percent compared to the equivalent period a year earlier, when the level averaged 60.67 euros per MWh, data provided by power grid operator IPTO has shown.

It should be pointed out that a direct price comparison of all components making up wholesale cost during these two quarters is not possible as, during this time, the structure of the wholesale electricity market changed from a mandatory pool system to the target model.

For example, a minimum RES-supporting surcharge burdening wholesale costs by an average of 3.4 euros per MWh during the first quarter last year has since been abolished. Also, the market-clearing price fell to 0.72 euros per MWh in the first quarter from 2.11 euros per MWh in the equivalent period a year earlier.

Even so, the reduction in these costs was outweighed by the increase in wholesale electricity prices. The total cost in the day-ahead and intraday markets averaged 55.17 euros per MWh in the first quarter this year, compared to last year’s average cost of 50.39 euros per MWh in the mandatory pool.

Surcharge costs also increased, averaging 9.53 euros per MWh in the first quarter this year, double the level of 4.78 euros per MWh a year earlier.

Particularly high prices registered late in 2020, during the early days of the target model launch, have eased so far this year. Last November and December, surcharge costs reached 17 and 16.09 euros, respectively.

Electricity consumption fell by 6 percent in the first quarter this year, compared to a year earlier, to 12.39 TWh from 13.175 TWh, as a result of lockdown measures amid the pandemic.

Greek market coupling with Bulgaria scheduled for May 11

Greece’s next market-coupling step, a day-ahead market link with Bulgaria, following an equivalent step with Italy in December, is scheduled to take place on May 11 as part of a wider effort by Europe’s Nominated Electricity Market Operators and Transmission System Operators for a single European day-ahead market.

Preceding trial runs, started on March 16 and planned to take place until April 30, must be successfully completed before the Greek-Bulgarian day-ahead market link is given the green light for its launch.

Automatic energy flow from the more expensive to the less expensive electricity market is expected to initially prompt a slight reduction in domestic wholesale electricity prices.

Greater price convergence between the Greek and Bulgarian markets is expected to be achieved with the introduction of a second transmission line running from Nea Santa, northeastern Greece, to Bulgaria’s Maritsa area in the south. This second line promises to greatly boost transmission potential between the two countries.

The additional transmission line was originally slated for launch in 2023, but swift progress from the Bulgarian side has increased the likelihood of an earlier delivery, mid-way through 2022, according to Greek power grid operator IPTO’s ten-year development plan (2022-2031), forwarded for public consultation at the beginning of this year.

Until now, Bulgaria has clearly been the dominant electricity exporter in trading with Greece, but this role is expected to be reversed as of 2023 because Greek electricity prices will be relatively lower, according to ICIS, a specialized news portal covering energy and related domains.

Market coupling with Bulgaria expected by early May

Market coupling to unify the Greek and Bulgarian day-ahead markets, representing a second step for the participation of Greek wholesale electricity markets in a pan-European unification of markets through the target model, is planned for late April or early May, sources have informed.

The forthcoming step was preceded by market coupling between Greece and Italy, unifying, as of December 15, the day-ahead markets of the two countries through a single price coupling algorithm, EUPHEMIA (Pan-European Hybrid Electricity Market Integration Algorithm). It calculates energy allocation, net positions and transboundary electricity prices.

Greece’s market coupling with Bulgaria promises to create an even broader trading platform for market participants, sector officials noted. Besides bilateral contracts for energy imports and exports, market coupling will also facilitate automatic energy flow from the higher-priced country to the lower-priced country.

To date, Greece has clearly been an energy importer in its transboundary energy trading relationship with Bulgaria. It remains to be seen if this will be maintained under the new conditions.

Once market coupling of the Greek and Bulgarian day-ahead markets has been accomplished, Greece’s next step towards unification with European energy markets will be to link its intraday market with that of Italy, a step expected by next summer, through the implementation of complementary regional intraday auctions (CRIDA).

Further ahead, a third step, balancing market coupling through two European platforms, MARI (Manually Activated Reserves Initiative) and PICASSO (Platform for the International Coordination of Automated Frequency Restoration and Stable System Operation), is planned for the second half of 2022.

 

Day-ahead market prices unusually low despite crisis conditions

Though the balancing market and its various problems since November’s launch of new target model markets may have been the focus of attention of late, irregularities have also troubled the day-ahead market, necessitating a closer look, officials have stressed.

This need was first pointed out by Alex Papalexopoulos, one of the architects of the country’s electricity system, who observed that the day-ahead market has shown signs of offers being systematically submitted at levels below actual cost. He said market dumping was taking place, referring to offers submitted by lignite-fired units.

These concerns have now also been raised by Dinos Benroubi, head of energy supplier Protergia’s electricity and gas divisions, as well as Antonis Kontoleon, the chief official at EVIKEN, Greece’s Association of Industrial Energy Consumers.

At a time of crisis, high electricity demand and calls on industrial producers to hold back on energy consumption, day-ahead market prices remain very low and full-scale electricity exports are taking place towards Italy, Kontoleon noted during a panel discussion at Athens Energy Dialogues, a conference held yesterday.

Protergia’s Benroubi took the issue a step further by noting that RAE, the Regulatory Authority for Energy, must implement a monitoring mechanism for the day-ahead market, as, despite serving as a base for the target model’s functioning, it is displaying irregularities.

Greek-Italian market coupling boosts transaction efficiency

The Greek-Italian electricity market coupling of day-ahead markets, launched on December 15 as part of the target model, is living up to its expectations as a safety valve facilitating optimal electricity flow between countries.

The initiative, operating through a single price coupling algorithm, EUPHEMIA (Pan-European Hybrid Electricity Market Integration Algorithm), which calculates energy allocation, net positions and transboundary electricity prices, has run smoothly since its launch over a month ago.

Greek-Italian transboundary electricity transactions admittedly enjoyed a high level of maturity prior to the introduction of market coupling, courtesy of reliable price forecasts by participants for the Greek and Italian markets.

A grid interconnection, in the form of a 163-km, 400-kV voltage and 500-MW capacity subsea cable, has been in service since 2002.

However, the market-coupling initiative has taken the efficiency of these transboundary Greek-Italian electricity transactions to a higher level as auctions allocating grid interconnection capacities are no longer required.

Since the mid-December coupling of the Greek and Italian energy markets, electricity has constantly flowed from the market offering lower prices to the higher-priced market, proving this market system’s ability to utilize interconnections to their fullest.

Market coupling of the Greek and Bulgarian day-ahead markets is planned to follow, its launch scheduled for spring.

An increased number of interconnected electricity markets promises to give the Greek wholesale electricity market a regional role. However, transboundary grid interconnections will need to be upgraded if this is to be achieved.

CO2 right prices up 39% in 45 days, adding to wholesale market price ascent

CO2 emission right prices have hit new records, trading at levels of over 30 euros per ton in recent days for a rise of 39 percent over the past month and a half that has contributed to the wholesale market price ascent.

These elevated CO2 right levels peaked on Tuesday, at 32.02 euros per ton, well over a price of 23.05 euros per ton recorded just weeks ago, at the end of October.

The upward trajectory of CO2 emission right costs is also contributing to even higher prices in Greece’s wholesale electricity market.

Last Wednesday, the day-ahead market’s average price exceeded 80 euros per MWh, rising further to 93 euros per MWh hour yesterday.

If CO2 emission right trading prices persist at levels of more than 30 euros per ton, power utility PPC will activate a related wholesale price clause incorporated into its supply agreements.

Besides the increase in CO2 emission right costs, the Greek day-ahead market has followed the upward trajectory of other European markets, where the combination of higher demand and deteriorating weather conditions is pushing price levels higher.

According to Greek energy exchange data for today’s day-ahead market, the price will average 82.31 euros per MWh, peaking at 114.1 euros per MWh and dropping as low as 44.38 euros per MWh.

 

Market restrictions on the way for electricity cost reduction

Energy minister Costis Hatzidakis’ recommendations to gas-fueled electricity producers for price restraint in the market have proven to be just partially effective, prompting RAE, the Regulatory Authority for Energy, to forward for public consultation restrictive measures, which, when legislated, will limit the levels of offers by producers in the balancing market.

Balancing market costs have risen sharply over the past six weeks, since the launch of target model markets, leading to elevated wholesale electricity prices that are now being passed on to the retail market, affecting consumers in the mid and low-voltage categories – households and businesses.

Sixth week target model market data made briefly available yesterday by power grid operator IPTO before being swiftly removed from the company website admittedly showed a de-escalation of price levels compared to unrealistically high levels reached in recent weeks, but, on average, these latest levels remained considerably high.

Taking this latest data into consideration, along with sharp price hikes recorded in the day-ahead market, the energy ministry is fully aware of the fact that electricity market prices could spin out of control if action is not taken.

The package of measures forwarded by RAE for public consultation is intended to restore market rationalization. It remains to be seen if these measures will prove effective.

Non vertically integrated electricity suppliers, hit hard by the increase in wholesale prices, are pushing for retroactive implementation of these upcoming restrictions.

 

Industry opposes bilateral contract restrictions

EVIKEN, the Association of Industrial Energy Consumers, has expressed opposition to an energy exchange proposal, delivered through public consultation, calling for the imposition of restrictions on bilateral contracts reached by suppliers.

In its letter, EVIKEN notes that an upper limit restricting supplier bilateral contracts to 20 percent of total sales, if suppliers hold a retail electricity market share greater than 4 percent, ensures conditions of liquidity in the day-ahead market and prevents a squeeze on prices.

The association, in its letter, proposes that this regulatory measure be abolished in the day-ahead market given the extremely high price levels registered, noting its maintenance over an extended period threatens to create oligopolistic conditions in the market.

Legal action, even at an EU level, could be taken over the matter, crucially important for the industrial sector, EVIKEN indicated.

Greek-Italian market coupling, soon, target model’s next step

Domestic market players and officials are eagerly awaiting to see how the target model’s next stage, Greek and Italian day-ahead market coupling, scheduled for December 15, will influence wholesale electricity prices.

Wholesale electricity prices in the day-ahead market and, especially, the balancing market, have escalated since the target model launch in Greece a month and a half ago.

Greece’s market coupling with Italy will be a crucial step as it promises to take Greece to the essence of the target model effort, namely gradual unification of national energy markets – electricity and gas – into one common European market.

Once market coupling is established between Greece and Italy, energy will flow from the country with lower energy prices to the higher-cost country – to the extent permitted by grid interconnection capacities – until price discrepancies have evened out.

All preliminary work for next week’s Greek-Italian market coupling launch has been successfully completed. An ongoing dry-run procedure involving simulated trading will continue until December 12.

The market coupling launch, three days later, is on schedule, the Greek energy exchange has informed RAE, the Regulatory Authority for Energy.

Market coupling of Greece and Italy’s balancing markets will take place at a latter date, while Greek-Bulgarian market coupling is planned for early in 2021.

Target model markets showing signs of price de-escalation

Price levels in new target model markets – the day-ahead market and the balancing market – are showing signs of de-escalation following sharp wholesale electricity price rises over the past month that have caused major unrest among suppliers.

Though balancing market prices over the weekend were at levels of around 20 euros per MWh, even higher than last Friday’s price level of 19 euros, market data indicates these levels will drop tomorrow.

Electricity producers have changed their pricing policy, lowering price offers submitted, which indicates that price reductions should be on the way.

The next few hours of trading will be pivotal in illustrating whether the balancing market price problem is a persisting one or not.

A reassessment of the situation will be made as of today before decisions are made, the energy ministry has announced. Last week, the ministry made clear it would not hesitate to intervene if wholesale prices remained elevated.

“The wholesale market price issue is a very significant one for the Greek economy and, under no circumstances, would we leave it unchecked,” a ministry official told energypress. “RAE [Regulatory Authority for Energy] is examining all available data and the government, too, has tools which it is prepared to use if the situation does not normalize,” the official added.

During the target model’s first month, the balancing market’s cost reached 36 percent of the equivalent cost for all of 2019, which had totaled approximately 200 million euros.

Ministry set to intervene if wholesale prices do not fall

The energy ministry is seriously examining the prospect of imposing a price ceiling, next week, on wholesale electricity prices if they do not deescalate over the next three days.

Wholesale electricity prices have risen sharply since last month’s  launch of the target model, pitched by the government as a price-reducing tool.

Day-ahead market prices for today – based on offers made prior to on online meeting between energy minister Costis Hatzidakis and electricity producers – fell mildly to 77 euros per MWh from 90 euros per MWh on Thursday.

If current prices do not fall further, it is a matter of time before suppliers pass them on to the retail market. Prior to the target model, wholesale electricity price levels ranged between 55 and 60 euros per MWh.

Some suppliers are considering to activate cost-related clauses for their tariff prices, while others have done so already, sources informed.

Producers contend the ascent in wholesale electricity prices reflects actual market conditions, adding that their power stations were previously incurring operational losses under the preceding pricing system.

However, energy ministry officials believe producers are exploiting certain rules to artificially raise prices. Hatzidakis, the energy minister, has urged producers to heed the government’s call or face intervention as of Monday.

Producers content with target model markets, suppliers edgy

Any nervousness felt by producers over the target model’s new markets ahead of their November 1 launch are swiftly being quelled by rational trading results. On the contrary, non-vertically integrated suppliers have experienced cost increases and, as a result, are concerned about their company prospects.

Although it still too early to tell, electricity producers believe day-ahead market prices are reflecting actual conditions, rising with shortages and falling with any oversupply.

Day-ahead market prices began at 60.44 euros per MWh on November 11, fell as low as 41.11 euros per MWh on Saturday and rose to 68.36 euros per MWh for today.

These price levels for the day-ahead market, known as the System Marginal Price under the previous system, are regarded as being at rational levels.

Producers have also expressed satisfaction over the balancing market, a largely unknown entity prior to the target model’s launch. Prices have been high, enabling units with flexibility to ensure solid earnings.

Day-ahead market prices are projected to fall, which would subsequently limit electricity imports and require domestic power stations to operate for longer hours.

Higher earnings for producers mean greater costs for suppliers. Non-integrated suppliers are concerned about their prospects under such conditions.

Wholesale prices up on first 2 days of target model trading

The target model’s launch over the weekend was successfully staged with a full field of 45 participating players, but wholesale electricity prices were pushed slightly higher.

Saturday’s day-ahead price for yesterday’s opening day ended at 53 euros per MWh before rising considerably to 61 euros per MWh yesterday for today.

This increase may be the result of a lack of confidence felt by players as they adjust to new market ways. In addition, the entry into the grid of high-cost lignite-fired power stations to cover telethermal systems is another factor.

Though producers, suppliers, traders and renewable energy players all actively traded for the target model’s launch, they have yet to fully come to terms with the new market conditions.

It is a matter of time before the model’s new markets – day-ahead, intraday, balancing – find their rhythm and price levels are normalized, energy sector authorities have noted.

No major issues concerning procedural or technical matters have been reported.

The intraday market launch was smooth. Prices ended at levels set by the day-ahead market as corrections were not made.

As for the balancing market, a brand new tool for the entire system, price levels ended as anticipated, at levels set during dry-run testing in the lead-up to the target model’s launch.

The target model, representing the Greek electricity market’s most significant reform, will enable market coupling with equivalent European markets, a development ultimately expected to reinforce energy security; offer consumers greater financial benefits through transboundary competition; prompt competitive pricing in the wholesale market; facilitate further RES penetration; and, by extension, hasten greenhouse gas emission reductions and the decarbonization effort.

IPTO, handling target model’s balancing market, set for launch

Power grid operator IPTO has declared being fully prepared for its imminent target model role of managing the balancing market, one of the new market systems to come into effect this coming Monday, when the target model is set to be launched.

Besides being tasked with managing the target model’s balancing market, IPTO, in a widely unknown role, will also be responsible for measuring overall operations of the target model.

The balancing market, an extremely complex market system requiring fundamental changes compared to current practices, will perform real-time balancing of demand against available offers.

The energy exchange will be responsible for the target model’s day-ahead and intraday markets.

In the lead-up to the forthcoming launch, IPTO, challenged by pandemic-related obstacles such as travel and staff restrictions, needed to make a series of coordinated efforts. These have included development of information systems and corresponding interface systems with the energy exchange (BMMS, MSS, XBMS and MODESTO), plus staff training.

The target model, representing the Greek electricity market’s most significant reform, is essential for market coupling with equivalent European markets.

The target model promises to reinforce the country’s energy security, offer consumers greater financial benefits through transboundary competition, lead to fair and competitive pricing in the wholesale market, while also facilitating further RES penetration, and, by extension, hastening greenhouse gas emission reductions and the decarbonization effort.

Minister urges target model readiness for smooth launch

Energy minister Costis Hatzidakis has urged all target model officials – including RAE, the Regulatory Authority for Energy; power grid operator IPTO; the energy exchange and EnExClear – to have resolved any pending issues so that a smooth launch of the model may be achieved on November 1.

Describing the upcoming date as historic for Greece’s energy sector, the minister was essentially conveying concerns of energy producers, traders and suppliers, not yet fully convinced that all market systems will be in full working order for the imminent launch.

The balancing market, in particular, remains a concern. The energy exchange is overseeing the day-ahead and intraday markets and IPTO will manage the balancing market.

Simulated dry-run testing of these markets, conducted for a period of over two months to test their limits and operating ability ahead of the target model launch, was completed about a fortnight ago.

Greece’s lead-up to the EU target model has been affected by a series of delays. Hatzidakis, the energy minister, is clearly determined to see the target model procedure through, not only because it is an EU commitment but also because of its prospective market and consumer benefits.

The target model will result in market coupling, or harmonization of EU wholesale markets, the intention being to eliminate market distortions and intensify competition.

A final full-scale test of all market systems is scheduled for October 27 while all is anticipated to be ready on October 30 ahead of the November 1 launch.

New market dry-run testing to end this week, target model launch on Nov. 1

The dry-run testing procedure for market systems ahead of the forthcoming target model launch, scheduled for November 1, will be finalized at the end of this week, RAE, the Regulatory Authority for Energy, the energy exchange and power grid operator IPTO have jointly decided.

Dry-run testing of the day-ahead, intraday and balancing markets began on August 3 to test their limits and operating ability ahead of the target model’s launch, aiming for market coupling, or harmonization of EU wholesale markets.

Market coupling, to increase competition and lower wholesale energy prices, will ultimately lead to energy union, the EU strategy seeking to offer consumers secure, sustainable, competitive and lower-cost energy.

All domestic parties involved, as well as the energy ministry, have ascertained the Greek launch will take place on November 1 following previous delays.

Even during these final days of simulated testing, day-ahead market prices have, at times, continued to display discrepancies with Day-Ahead Schedule price levels.

This has been attributed to the absence, from dry-run testing, of many traders who participate in the Day-Ahead Schedule, meaning the price levels of the two situations are based on different data.

Though balancing market prices have improved considerably as the simulated testing has progressed, following discrepancies, conclusions cannot be made until actual market conditions come into effect.

Meanwhile, public consultation by RAE on a market monitoring mechanism and a market surveillance mechanism for the new markets is due to be completed next Monday.

The market monitoring mechanism will seek, through structural and performance indicators, to evaluate levels of concentration and the market power of each participant, while the market surveillance mechanism will focus on identifying and combating strategies detrimental to competition.

The next step, once the new markets are launched, will be to market couple, initially with the Italian market, by the end of the year, followed by the Bulgarian market, in the first quarter of 2021, Greek energy minister Costis Hatzidakis recently informed.

 

 

Safety mechanism to limit energy exchange fluctuations

Sizeable electricity price discrepancies – compared to day-ahead scheduling market levels – observed by officials in ongoing dry-run testing of Energy Exchange markets ahead of the target model launch scheduled for September 17 and attributed to unrealistic offers made by participants, are expected to narrow as more participants become involved.

Even so, officials supervising the simulated testing of all four Energy Exchange markets – day-ahead, intraday, forward, balancing markets – plan to introduce a safety mechanism enabling participants to make improved follow-up offers if price levels fluctuate beyond upper and lower limits.

Officials at related agencies and the energy ministry are confident the dry run will be completed on time despite being up against a very tight schedule.

The head officials of RAE, the Regulatory Authority for Energy, the energy exchange, and power grid operator IPTO held a summit meeting yesterday with energy minister Costis Hatzidakis and the ministry’s secretary-general, Alexandra Sdoukou, to discuss the progress of the dry run. Other officials meet on a weekly basis to discuss the effort.

To date, any technical issues that have arisen have been resolved. Both the Energy Exchange and IPTO appear ready for the real-life launch. Market systems have been undergoing continual testing since August 3.

However, a shortage in the number of dry-run participants, especially traders, has been observed. This is concerning as current evaluations of the market system performances cannot be considered entirely accurate. All key players – gas-based electricity producers, suppliers, traders, RES producers and aggregators – must be involved in the simulated testing for a dependable picture.

Once the Energy Exchange and IPTO have declared their readiness, RAE will need to offer its approval of the dry run on September 11, a week before the target model’s scheduled September 17 launch.

The aim is for all players to have entered the market systems on September 15 to prepare their orders for the launch two days later.

Crucial week for target model’s dry-run tests of market systems

Though any glitches that have emerged during ongoing simulated testing of all energy exchange market systems ahead of a target model launch scheduled for September 17 have been quickly resolved, officials remain concerned about the venture’s level of readiness.

The number of participants for the dry run’s virtual transactions, especially traders, has been insufficient, while participants are submitting unrealistic offers, officials have observed.

This has prompted major fluctuations as well as sizable electricity price discrepancies compared to day-ahead scheduling market levels.

Market systems at the Energy Exchange, to operate the day-ahead, intraday and forward markets, and at the power grid operator IPTO, operating the balancing market, have been undergoing continual testing since August 3.

This week will be crucial as an increase in the number of participants is anticipated, while heightened maturity in bidding methods is also expected, all of which should result in safer conclusions.

For the time being, a deferral of the target model’s September 17 launch date is not being considered. All operators must declare complete readiness to RAE by September 11 if this launch date is to be maintained.

Electricity price levels, once the target model is launched, cannot be forecast at present. This could be possible within the next few days.

Officials at the energy ministry, RAE, the Regulatory Authority for Energy, the energy exchange and IPTO, all monitoring the effort, are scheduled to stage their next weekly meeting tomorrow.

Energy exchange dry run starts, target model launch nearing

Simulated testing of all energy exchange market systems, the dry run, began yesterday, as officially scheduled, putting the launch of the target model on the final stretch.

Market systems linked to power grid operator IPTO, the Greek energy exchange, as well as EnexClear, an energy exchange subsidiary tasked with clearing transactions, are now operating under conditions of virtual reality, signaling the beginning of final-stage testing to be completed at the end of this month.

During the dry run, participating producers and buyers will be making simulated offers and purchases, the objective being to identify possible operational faults or insufficiencies for correction ahead of the official launch of the target model, scheduled for September 17.

All four energy exchange markets – the day-ahead, intraday, forward and balancing markets – are being tested. The energy exchange is in charge of the first three while IPTO is operator of the fourth.

Following August 11, EnexClear will take on a more active role for transaction clearances, a procedure to be performed on a weekly basis.

The overall procedure’s schedule was formalized by a ministerial decision signed on July 10.
