IPTO regulatory framework for RES output cuts in the pipeline

Posted on by admin

Power grid operator IPTO plans to soon work on a regulatory framework intended to configurate RES output cuts, the operator’s CEO Manos Manousakis has told an annual event staged by the Greek Wind Energy Association (ELETAEN).

IPTO will establish a working group with ELETAEN to examine RES grid injection restrictions that will need to be applied whenever necessary to ensure grid stability, the IPTO chief noted.

The prospective regulatory framework is intended to eventually replace a formula already being applied by IPTO for universal and proportional cuts in RES production.

The framework’s criteria will be fashioned in accordance with the grid’s features and needs, essentially meaning RES cuts will vary depending on RES unit technology.

Until the regulatory framework is drafted, IPTO, as a transitional solution, will continue cutting RES grid injections based on the production capacity of respective RES units.

RES investors have underlined the regulatory framework for RES output cuts will affect projected revenues of RES units and, as a result, is already impacting their negotiations with banks for loans concerning new projects.

Cuts on small-scale and large-scale RES units will need to be proportional, rather than based on the operator’s technical capabilities, investors have noted.

 

 

IPTO forwarding RES cut formula for consultation

Posted on by admin

Energy sector authorities are close to announcing a formula already being applied unofficially for emergency RES output cuts as a means of preventing grid overload risks and ensuring stability when domestic electricity demand is low and green-energy production is high.

Power grid operator IPTO intends to forward its formula to RAAEY, the Regulatory Authority for Waste, Energy and Water, this week for consultation before it is officially adopted, energypress sources have informed.

IPTO’s current formula is being applied across the board and proportionally, effectively meaning RES output cuts are based on generation capacity at the time of intervention rather than the respective installed capacities of facilities.

If, for example, RES output has reached a total of 5,000 MW and authorities determine that it needs to be cut by 500 MW, then production of all operating RES units would be cut by 10 percent.

IPTO’s proposal for the consultation procedure will also include provisions ensuring transparency when RES cuts are made.

April power usage falls 3.11%, down for 11th month in a row

Posted on by admin

Electricity usage in Greece fell for an eleventh successive month in April, down by 3.11 percent compared to the equivalent month a year earlier, a latest monthly report by power grid operator IPTO has shown.

Electricity usage over the eleven-month period fell by 15.09 percent, a record drop for such a time span, the operator noted.

The contraction in demand has been attributed to two factors, the efforts by consumers, small and large-scale, to restrict electricity expenses, as well as mild weather conditions.

Households and low and mid-voltage businesses reduced their electricity usage by 2.8 percent in April, while energy-intensive industries cut back on consumption by 6.4 percent.

Over the year’s first four-month period, overall electricity demand fell by 9 percent, the IPTO report showed.

Crete set for hybrid RES station installations offering 120 MW

Posted on by admin

An energy ministry decision, either imminent or already signed, will pave the way for the installation of hybrid RES stations on Crete offering a total capacity of 120 MW, energypress sources have been informed.

This ministerial decision comes as a follow-up to legislation for a support framework concerning the development of RES facilities equipped with energy storage units on the Greek islands, a plan endorsed by the European Commission.

It is divided into three sections. Crete belongs to the framework’s second section, while the plan’s first section includes small islands, such as Gavdos, not planned to be incorporated with the mainland grid through power grid operator IPTO’s interconnection program. The third section of the plan concerns islands now undergoing interconnection procedures.

The 120 MW in hybrid stations to be installed on Crete will receive tariffs determined administratively rather than through auctions, as the island needs to secure energy sufficiency as soon as possible, leaving no time for competitive procedures.

Of Crete’s 120 MW in prospective hybrid stations, four projects offering a total capacity of 84.45 MW lead the race for securing tariffs, as their licensing procedures have reached an advanced stage.

Five areas selected for first stage of offshore wind farms

Posted on by admin

Five areas marked out to host Greece’s first phase of offshore wind farms, planned to offer a total capacity of 2.1 GW, are located in the north and central Aegean, as well as off Crete.

The area in the north is situated off Alexandroupoli, three areas are close to mainland Greece and the wider Dodecanese area, while a fifth spot is off eastern Crete, at an area between Sitia and Xerokampos.

The area off Alexandroupoli is planned to host pilot projects offering a total capacity of 600 MW. The Copelouzos group secured a 216-MW production license for offshore parks in this area back in 2012. Contracts for their development will not undergo any competitive procedures as these projects have been classified as pilot projects.

The three areas chosen to host offshore wind farms in the central Aegean will each host wind farms with respective capacities of 300 MW for a total of 900 MW.  It has not yet been determined if these offshore wind farms will be located close to the mainland or in the wider Dodecanese area.

The wind farm off Crete, near the northeastern shoreline, is planned to offer a total capacity of 600 MW.

Environmental, spatial, social, economic and geopolitical criteria, along with wind intensity, a decisive factor determining the degree of return on investment, were taken into consideration when selecting the aforementioned areas.

Power grid operator IPTO has already delivered precise data on the grid absorption potential at each of these clusters. However, the plan still needs to be approved by the Hellenic National Defence General Staff.

RAE, IPTO pushing ahead to integrate traders into intraday market

Posted on by admin

Intraday electricity market participation by traders engaged in transactions concerning the country and non-coupled neighbors – Albania, Turkey and North Macedonia – a complex matter that has remained pending for years, is now on track to be approved by RAE, the Regulatory Authority for Energy, and power grid operator IPTO.

One of the basic steps needed is the establishment of Daily Intraday Capacity Auctions, a step requiring the approval of all respective operators involved. According to sources, all operators involved have expressed willingness to proceed, but the overall process will take time to complete.

IPTO has already declared its readiness, from a technical perspective, to implement these auctions, which, however, is not the case for other operators as they are active in markets still at early stages of development. These operators still need to make adjustments in order to accommodate Daily Intraday Capacity Auctions into their systems.

IPTO has been actively involved, underlining, to neighboring operators, its availability to contribute to their efforts.

The addition of traders to the intraday market promises to boost its liquidity as more participants become involved. This development will greatly improve the ability of market players to correct their positions and, as a result of this greater flexibility, limit their balancing market costs.

Also, the more precise activity of market players will create conditions limiting the volumes of electricity needed in the balancing market.

No changes to RES, energy storage grid injection limit plan

Posted on by admin

The energy ministry has completed work on a ministerial decision designed to restrict injections into the grid by new RES and energy storage units and plans to sign it off within the next few days as the matter is one of the energy sector’s pending issues the ministry wants to have settled ahead of the May 21 legislative election.

According to sources, formulas proposed by power grid operator IPTO and distribution network operator DEDDIE/HEDNO have been maintained for the ministerial decision.

The ministry’s decision to impose grid injection restrictions was taken in order to make optimal use of available electrical capacity in the transmission and distribution system and ultimately maximize the number of green-energy power plants.

According to the legislative revision, the energy injection restrictions will not be able to exceed 5 percent of the respective annual capacities of units subject to the limit.

The measure will apply to all RES plants under development and possessing finalized connection offers, as well as to green-energy projects for which connection requests have been submitted to either DEDDIE/HEDNO or IPTO. Batteries will also be subject to the injection restriction, regardless of whether they have been incorporated into RES systems or not.

IPTO confident of energy sufficiency this coming summer

Posted on by admin

Greek power grid operator IPTO, contrary to officials in other parts of Europe fearing drought periods will affect their electricity sufficiency, is confident current local conditions are favorable enough to get the country through the high-demand summer season.

Reservoir water levels at Greek power utility PPC’s hydropower facilities have just about been maintained at last year’s levels, more RES units have been connected to the grid this year than ever before, while the country’s lignite stocks are also currently high, at three million tons, following a concerted energy-crisis effort made since last year.

In addition, Greece’s grid is set to be reinforced, within the next couple of months, by the addition of two new power stations – a Mytilineos group unit and PPC’s Ptolemaida V – to offer an extra generation capacity of 1,500 MW.

Reservoir water levels at PPC’s hydropower plants currently offer 2,720 MW and are expected, over the next few days, to rise to 2,850 MW, levels recorded last year, primarily as a result of increased flow at northern Greece’s Haliacmon river.

All 4 bidders seeking Ariadne Interconnection 20% advance

Posted on by admin

All four first-round entrants in a tender offering a 20 percent stake in Ariadne Interconnection, a subsidiary founded by power grid operator IPTO to specifically develop the Crete-Athens grid interconnection, have qualified for the procedure’s next stage following approval by RAE, the Regulatory Authority for Energy.

GEK-TERNA; a partnership involving Macquarie Super Core Infrastructure Fund and Phaethon Holdings (Copelouzos group); Italian operator Terna SpA; and StateGrid International Development Belgium are the four entrants advancing to the tender’s second round.

IPTO tasked RAE with an appraisal of the tender’s first-round entrants to safeguard the overall procedure from any prospective legal challenges.

One matter inspected by RAE was whether participation by entrants active in electricity production could lead to conflict of interest.

The authority also decided that China’s SGCC, IPTO’s strategic partner with a 24 percent stake, is eligible to participate in this tender, through its Belgian subsidiary StateGrid International Development Belgium.

Greek-Egyptian GREGY grid link prospects face crucial period

Posted on by admin

A Memorandum of Understanding for the entry of Greek power grid operator IPTO into the equity make-up of Elica, a subsidiary of the Copelouzos group established to promote the 3.5 billion-euro Greek-Egyptian GREGY Interconnector, along with a corresponding move expected from the Egyptian operator EETC, undoubtedly represent votes of confidence for the project.

The interest shown by the two operators to become stakeholders in the GREGY Interconnector project boosts its development prospects ahead of an EU announcement, in June, of a shortlist of projects seeking PCI/PMI list inclusion for the next two years.

Three studies crucial to the development of the GREGY Interconnector, promising to transmit green energy to Europe, are planned to be commissioned over the next couple of months.

One of the three studies will focus on technical details, a second will examine the project’s financial aspects, while a third study, a challenging seabed mapping procedure to scan the project’s underwater setting over a distance of 954 kilometers, will take no less than six months to complete. Weather conditions will play a big role in this third study’s duration.

If all goes according to plan, a final investment decision sanctioning the project’s development is expected within 2024.

Mytilineos uses aggregator permit for country’s first demand-response transaction

Posted on by admin

The Mytilineos group, through a portfolio including its Aluminium of Greece company, has become the country’s first company to use an aggregator (FOSE) permit in a demand-response program, established as part of an EU proposal aiming to reduce energy consumption by 5 percent.

The Mytilineos group conducted its first such transaction on May 28, energypress sources informed.

In the lead-up, RAE, the Regulatory Authority for Energy, had approved a 500-MW permit for Mytilineos to use in this demand-response program, while power grid operator IPTO conducted trial runs to ensure the system’s platform was ready to operate.

The demand response system enables variation of electricity consumption by end-users such as commercial and industrial enterprises in order to balance the electricity network during periods of peak production or consumption.

Sympower Greece, also holding a 500-MW aggregator permit for the demand-response program, has registered to participate but had not conducted any transactions until last Friday, the sources noted.

NRG holds a 100-MW aggregator permit for the the demand-response program, Optimus Energy possesses a 350-MW permit, power utility PPC holds a 1,500-MW permit, and Elpedison holds a 500-MW permit. These companies are believed to be preparing to conduct their first aggregator demand-response transactions.

 

RAE deciding on Ariadne Interconnection 20% stake shortlist

Posted on by admin

A shortlist of second round qualifiers in a tender offering a 20 percent stake in Ariadne Interconnection, a subsidiary founded by power grid operator IPTO to specifically develop the Crete-Athens grid interconnection, is expected to be decided on by RAE, the Regulatory Authority for Energy, at a meeting today.

Participants approved by the authority will advance to the tender’s second round for binding bids.

A total of four participants entered the tender’s first round, these being Macquarie Super Core Infrastructure Fund & Phaethon Holdings; GEK-TERNA; Italy’s Terna SpA; and StateGrid International Development Belgium.

The regulatory authority needs to decide which of these entrants fulfil conditions and terms for qualification to the second round of this tender, staged by IPTO.

The operator has tasked RAE with this appraisal, the objective being to safeguard the overall procedure from any prospective legal challenges. One of the matters being inspected by RAE is whether entrants active in electricity production can take part, as this could lead to conflict of interest.

Another is whether China’s SGCC, IPTO’s strategic partner with a 24 percent stake, is eligible to participate in this tender, through its Belgian subsidiary StateGrid International Development Belgium.

Work on the the Crete-Athens grid interconnection is in progress, IPTO recently informed.

Storage unit permit processing inconsistencies causing issues

Posted on by admin

Investors seeking to make progress with environmental permit procedures for standalone batteries ahead of an inaugural auction that will offer investment and functional support to energy storage units find themselves facing differing processing speeds at various licensing authorities around the country.

These delays have been largely attributed to the fact that licensing authorities have been tasked with granting licenses for energy storage units for the first time, a newness causing some hesitancy.

The problem is even more acute for energy storage projects with capacities of up to 100 MW as they also require approval from regional authorities, despite an energy ministry circular specifying that an environmental report is sufficient. In some cases, additional information and supporting documents are being requested by certain regional authorities.

Although the issue has generally been straightened out in recent months, differing processing speeds for environmental permit applications remain.

Power grid operator IPTO has received applications to connect standalone batteries representing a total capacity of 5,340 MW, a pool regarded as sufficient for the inaugural auction offering investment support to go ahead.

The differing licensing speeds for energy storage units are resulting in a greater accumulation of such projects in areas where authorities are less demanding.

If energy storage projects end up being excluded from auctions as a result of not possessing environmental permits, then the objective of an even geographical spread of such projects may not be achieved.

A sum of 200 million euros stemming from the Recovery and Resilience Facility (RRF) will be offered as investment support for energy storage units under the condition that an inaugural auction is staged by late June.

This essentially means that RAAEY, the Regulatory Authority for Waste, Energy and Water, will need to officially announce a first auction by mid-May, an initiative requiring a related ministerial decision.

Grid overcomes Easter’s grid overload scare with little action

Posted on by admin

The country’s grid emerged untroubled by an overload scare concerning the Greek Easter long weekend, a situation prompted by the combination of high RES output, a lower-cost energy strategy planned by the grid operators, and low demand.

Overcast weather in most parts of the country restricted solar energy output, sparing power grid operator IPTO of the need to intervene in order to protect the grid from being overcharged amid low-demand conditions.

Had action been necessary, IPTO planned to orchestrate a highly complex combination of moves that would have included restricting electricity imports, deactivating as many power stations as possible and significantly cutting RES input.

As it turned out, Good Friday was the most challenging day for the grid, as cloudy weather on Easter Saturday and Easter Sunday proved pivotal in helping authorities overcome the overcharge threat.

IPTO, coordinating with distribution network operator DEDDIE/HEDNO, only needed to make limited RES cuts.

IPTO moves fast to issue 4,250 MW in RES connection offers

Posted on by admin

Power grid operator IPTO has issued connection offers totaling a capacity of 4,250 MW for RES projects seeking grid space since the arrival of a recent ministerial decision signed last August and revised in late January to shape the procedure’s details, including its fast-track priority system.

The operator has also received a substantial number of applications for a first wave of standalone batteries representing a total capacity of 5,340 MW. These applications have already received environmental permit, meaning the turnout for an upcoming investment support program expected to be staged by the end of June will be considerable.

A ministerial decision will need to be issued this month so that a first auction may be staged within Recovery and Resilience Facility (RRF) fund deadlines.

Green aggregators hit by price cap, big non-compliance penalties

Posted on by admin

Green aggregators, believing their balancing costs are excessive, causing cash-flow problems and creating additional cost passed on to customers, have called for intervention and revisions from power grid operator IPTO and RAE, the Regulatory Authority for Energy.

RES units operating under incremental support contracts have assumed full balancing responsibilities for their electricity generation since November 30, when Greece entered Europe’s cross-border intraday XBID continuous market, through coupling with Italy and Bulgaria.

However, the implementation of a cap on the day-ahead and intra-day markets has created broader risks for green aggregators, including overestimating RES generation levels.

In such an event, the overestimation’s discrepancy is initially compensated based on the clearing price of the day-ahead market, or price cap, and then priced at the balancing market’s deviation price, which is not capped and may be many times over the day-ahead market level, a financial setback for green aggregators.

New non-compliance charges introduced on December 1 as a result of the cap represent an additional problem for green aggregators as they can lead to exceptionally high penalties, reaching levels well over those of balancing costs.

Grid facing overload challenge this Greek Easter Sunday

Posted on by admin

A drop in electricity demand forecast for this coming Greek Easter Sunday, combined with high renewable energy contribution to the energy mix, could prove to be a major test for the country’s grid, as was the case on March 26, when such a combination forced the power grid operator IPTO to cut back on RES production over extended periods in order to protect the grid from voltage overloads as demand plunged to just over 500 MWh for an hour.

Ioannis Margaris, Deputy Chairman at IPTO, highlighted the danger at the recent Power & Gas Forum in Athens, noting the grid is operating on edge and will be tested during the Greek Easter break.

In its weekly outlooks, IPTO had recently forecast a load of 4,390 MW and demand of 1,330 on March 26 at 2pm, before actual demand ended up reaching just over 500 MW.

For this coming Easter Sunday, IPTO has forecast loads of as low as 3,750 MW during the midday hours, meaning the operator is expecting another challenge that could be even trickier than the recent encounter. A day earlier, on Easter Saturday, IPTO has forecast a higher load of 4,800 MW for the midday hours.

To combat the grid-overcharge threat, IPTO plans to orchestrate a highly complex combination of moves that will include restricting electricity imports, deactivating as many generation units as possible and significantly cutting RES input.

Hydropower grid input crucial under current conditions

Posted on by admin

Greater reliance on power utility PPC’s hydropower plants is proving to be a crucial grid-sufficiency move under the current conditions, combining deeper RES penetration and lower energy demand, a higher-risk situation should demand rise, as is expected in coming days.

According to sources, power grid operator IPTO has called for greater hydropower coverage of the country’s energy mix to secure grid stability. Though this is not a new approach, greater usage of hydropower, an energy source offering flexibility to the system, has been deemed as necessary under the current conditions.

The low-demand period is expected to rise sharply during the Greek Easter break this coming weekend, putting the grid to the test.

However, officials need to carefully manage the country’s hydropower plants so that water levels are kept at satisfactory levels ahead of summer. Rainfall is forecast to be mild over the next month and a half. Current hydropower usage has exceeded levels that had been initially anticipated by PPC, but reservoir levels remain at desired levels, sources informed.

IPTO’s necessary RES injection limits universal, proportional

Posted on by admin

Power grid operator IPTO is examining a number of factors concerning periods that combine low domestic electricity demand with high RES production, the most recent example being the March 25-26 weekend, in order to decide on an optimal formula protecting the grid’s security and stability.

Net-export periods limit the need for extraordinary measures, while, on the contrary, net-import periods require far greater caution.

Getting the balance right for an optimal formula regarding RES contributions to the grid is far trickier when high RES output primarily stems from abundant sunshine. Under such conditions, significant proportions of green-energy injections are provided by small-scale PV units not detectable by DEDDIE/HEDNO, the distribution network operator, as a result of the grid’s shortage of telemetrics, which offer automatic measurement from remote sources. If the grid were equipped with sufficient telemetrics, the operator’s task of intervening accordingly to get the balance right would be made simpler.

Conditions combining low electricity demand and high RES production are a new reality that will continue to exist for many years, until energy storage technologies have matured sufficiently and become an integral component of the grid.

Until then, IPTO must – and already has – deploy solutions such as limiting both electricity imports and RES output injected into the grid. For the time being, grid-injection limits on RES producers are being imposed universally and proportionately.

Power usage in February falls for 8th month in a row, down by 2.25%

Posted on by admin

Electricity usage in Greece fell for an eighth successive month in February, dropping by 2.25 percent, compared to the equivalent month a year earlier, data in a latest report from power grid operator IPTO has shown.

However, the February drop was far milder than the 13.78 percent electricity usage decline recorded in January.

Consumers in Greece used an electricity amount of 4,069 GWh in February, down from 4,163 GWh in February, 2022.

Monthly electricity usage in the country has not stopped declining since an initial fall registered last July.

Renewable energy dominated February’s energy mix, capturing a 41.2 percent share, followed by gas-fueled power stations, with 22.5 percent, and lignite-fired power stations, at 15 percent.

As for retail electricity market shares, power utility PPC, the dominant player, gained 2.5 percent in February. compared to the previous month, for a 62.58 percent market share.

Among the independent suppliers, Protergia, a member of the Mytilineos group, remained at the forefront in February with a 7.44 percent retail market share, down from 10.53 percent a month earlier.

The country’s two other vertically integrated energy groups followed. Heron ended January with a 7.03 percent market share, up from 6.83 percent, and Elpedison captured a 5.91 percent market share, down from 6.02 percent.

Elsewhere, NRG captured a 4.82 percent retail electricity market share in January, up from 4.55 percent, followed by Aerio Attikis at 2.78 percent, marginally above the previous month’s 2.66 percent; Zenith registered 2.23 percent (2.17%); Watt & Volt was at 2.09 percent (2.06%); and Volterra captured 1.81 percent (1.8%). The remainder of suppliers shared a total of 3.3 percent.

 

IPTO facing grid-sufficiency challenge this coming Easter

Posted on by admin

Current energy market conditions, combining reduced electricity demand and deeper penetration of the energy mix by renewables, have emerged as a grid-security challenge for power grid operator IPTO, raising fears of power outages.

Output by RES units is generally on the rise and periods of low energy demand, such as the present, oblige the operator to manage a grid that is highly reliant on green energy, representing over 50 percent of the energy mix.

A sharp rise in energy demand expected during the upcoming Easter period and the subsequent dip pose an even greater challenge for the operator, required to manage the RES-dominated grid without support from energy storage units, still not part of the energy market picture but expected to figure more prominently in coming years.

Officials at RAE, the Regulatory Authority for Energy, note IPTO has fully informed the authority on the challenges it faces and action it plans to take to remedy the situation.

IPTO may choose to cut back on RES reliance. A second measure may entail limiting electricity imports through a freeze on interconnection rights.

Ioannis Margaris, Deputy Chairman at IPTO, highlighted the tricky situation faced by the operator at last week’s Power & Gas Forum in Athens.

“Our operations are on edge,” he noted, describing high-risk periods when low demand is combined with high RES penetration and mass withdrawal of conventional power stations, adding the problem will be exacerbated as Easter approaches. “Easter will be a big test.”

‘Incentives for battery additions to PVs would free up grid space’

Posted on by admin

Power grid operator IPTO’s Deputy Chairman, Ioannis Margaris, participating in a panel discussion at yesterday’s second and final day of the Power & Gas Forum in Athens, proposed incentives for behind-the-meter energy storage unit additions to still-unelectrified solar panel installations as a means of making available extra grid capacity for new RES projects.

Efficient use of the grid’s limited capacity is crucial. Authorities have already warned that unless drastic action is taken, the country’s grid capacity is headed towards exhaustion in the coming years.

At present, occupied grid capacity totals 25 GW, 11 GW concerning RES projects already operating and 14 GW concerning active final connection offers, the IPTO deputy noted.

Margaris stressed that grid access in many parts of the country will soon become unavailable given the large number of RES project connection applications submitted by investors to IPTO.

Stricter terms limiting the duration of connection offers for stagnant projects, a measure that was recently ratified in Parliament as part of a multi-bill submitted by the energy ministry, will help free up valuable grid capacity, the IPTO deputy stressed.

Also taking part in the forum’s panel discussion, Dr. Stavros Papathanasiou, Professor at the National Technical University of Athens (NTUA), agreed that a solution concerning the addition of energy storage units to RES projects will, sooner or later, need to be adopted.

Adding behind-the-meter batteries to solar panel systems, either under development or already operating, is the only option to avoid big project cuts as the objective is to accommodate as many RES units as possible into the grid’s limited capacity, the professor stressed.

Battery additions will, of course, increase the cost of solar energy projects, but this increase should not add more than 15 to 20 euros per MWh to the cost of electricity produced by each project, assuming batteries with a duration of between 0.5 and one hour are installed, Papathanasiou informed.

 

Crete unable to take on more grid links, IPTO informs GAP Interconnector

Posted on by admin

The Cretan grid cannot take on any further interconnections as power grid operator IPTO’s Crete-Peloponnese and Crete-Athens grid links, plus the Cyprus-Crete subsea cable connection planned by EuroAsia Interconnector have exhausted the island’s capacity, IPTO officials have underlined.

IPTO officials, at a recent meeting with representatives of the Eunice Group, heading the effort for development of the GAP Interconnector (Greece-Africa Power) project, informed of Crete’s inability to take on any further interconnections, according to IPTO sources. An alternative route for the GAP Interconnector not involving Crete will, as a result, be needed, the IPTO officials have asserted.

GAP Interconnector officials want to develop their project as a means of importing RES-generated energy from Egypt to mainland Greece via Crete.

The plan entails installing two subsea cables, offering a 2,000-MW capacity, from coastal Matruh in Egypt to Crete’s Atherinolakko, a distance of approximately 450 kilometers.

Any new major grid interconnection involving Crete would hamper the local grid’s ability to operate safely and reliably, while also endangering the grid, itself, and interconnections, IPTO officials warned.

Stalled RES projects totaling 3.6 GW to face ultimatums

Posted on by admin

RES projects that have received final connection offers in the past from power grid operator IPTO but have remained stagnant as a result of failing to submit contract applications will be set deadlines, as part of an energy ministry effort to free up urgently needed grid capacity.

A related amendment has been included in an energy ministry multi-bill covering a range of matters. It will be taken to Parliament next week for debate and ratification.

Older RES projects representing a total capacity of 2.4 GW are estimated to have stalled since receiving final connection offers, along with a further 1.2 GW in green-energy projects that had submitted their applications collectively.

Sector officials believe that older RES projects representing 1.5 GW of this 3.6 GW tally in stalled projects will be withdrawn as a result of the deadlines to be set by the energy ministry, freeing up coveted space for new RES investments.

According to the ministry’s new terms, RES projects that received final connection offers up until December 31, 2020 will need to submit their contract applications by June 30, 2023. RES projects that received final connection offers between January 1 and December 31 in 2021 will have until August 31, 2023 to submit contract applications.

RES units currently operating in Greece represent a total capacity of 11 GW.

A much-delayed section of a power transmission line project in Greece’s west, dubbed the Western Corridor, for which its developer, IPTO, the power grid operator, was forced to bypass a monastery in the Kalvryta area following objections and legal action taken by its nuns, is expected to be delivered by the end of this month, enabling the wider project’s launch by mid-April, energypress sources have informed.

The new 400-KV double circuit transmission line will enable a high-voltage center in Megalopoli, central Peloponnese, to be connected to 400-KV circuits at Antirio, on the mainland’s southern coast. This will boost the Peloponnese’s existing transmission line connections, currently entirely facilitated by 150-KV transmission lines linked with the wider Athens area and western Greece.

The new Western Corridor transmission line, comprised of aerial, underground and underwater sections, has been 98-percent ready since 2019, the missing link being a section that was originally planned to run by the monastery, at a 500-meter distance. Legal action taken by the Kalavryta-area monastery’s nuns blocked the installation of two pylons, forcing a change of course further away from the monastery.

This section’s development was put on hold for several months as a result of the legal action taken by the monastery.

The project’s launch will not offer additional grid capacity for RES projects. RAE, the Regulatory Authority for Energy, has already factored in the additional increased capacity that would be freed up by the project.

Increased grid capacity will, however, be made available for new RES project additions once the Eastern Corridor, a 400-kV transmission line linking Megalopoli, Corinth and Athens, is completed.

PPC close to signing first PPAs with industrial consumers

Posted on by admin

Power utility PPC and a number of industrial players are examining a series of details, including legal matters, before signing the country’s first round of power purchase agreements (PPAs) for supply of lower-cost green energy.

PPC and industrial consumers are aiming to sign PPAs by Monday, though it remains uncertain if this target will be achieved, energypress sources have informed.

Procedures leading towards the country’s first PPAs between PPC and industrial groups have moved rapidly since a recent announcement by RAE, the Regulatory Authority for Energy, exempting PPAs from a wholesale electricity market price cap. This measure comes into effect as of tomorrow.

The PPAs involving PPC and industrial consumers are planned to have ten-year durations. Industrial consumers will need to be supplied electricity through thermal power stations for the first two years of these ten-year periods, providing energy supply coverage until new and required RES facilities being developed by the power utility are up and running.

PPC’s launch date of new solar farms, which will ensure green energy supply to industrial consumers, is a key matter in the final-stage talks before PPAs are signed. According to sector officials, these RES projects are expected to be launched in 2025.

Some of these RES facilities have already obtained connection terms from power grid operator IPTO, but most have not, preventing absolute certainty of their launches in 2025, as projected.

Heightened market activity ahead of demand-response service launch

Posted on by admin

Preparations are in full swing for the introduction of a demand-response service into the wholesale electricity market, expected to be launched in the coming weeks, initially in the balancing market, followed by other energy exchange markets.

Although this is still a relatively new service in Europe and internationally, strong interest is being expressed by participants in Greece, sources have informed.

Companies wishing to take part in the demand-response service need to take care of three key issues as part of their preparation.

Firstly, they must successfully integrate an appropriate operating system and become familiar with it, by no means an easy matter, according to the same sources.

Secondly, companies need to recruit and train appropriate personnel for this service.

A third step interested parties will need to take to complete their preparation process is to convince partners of the importance and value of the demand-response service.

According to market estimates, providers are not confronting solid resistance, but some degree of skepticism does exist, which is no surprise given the service’s novelty aspect.

According to market officials closely following the overall process, power grid operator IPTO has prepared well and is currently in the process of settling certain pending issues, including configuration of web services facilitating communication between participants and the operator.

Power demand continues fall in January, RES dominate output

Posted on by admin

Electricity demand plunged by 13.24 percent in January, compared to the same month a year earlier, registering a drop for a seventh successive month, a monthly report published by power grid operator IPTO has shown.

Households, businesses and industrial producers have cut back on power usage in an effort to contain their energy costs.

January’s contraction in electricity demand ranks as the second-biggest recorded during the seven successive months of decline and is one of the biggest reductions ever recorded in Greece.

Households registered the biggest cut in electricity usage in January, down 15 percent compared to January, 2022, while heavy industry also cut back on consumption, by 7.8 percent, the January figures showed.

Overall electricity demand fell to 4,235 GWh in January from 4,881 GWh in January, 2022, the IPTO data showed.

Subsequently, the drop in electricity demand prompted a generation reduction of 25.75 percent in January, compared to the same month a year earlier, according to the IPTO data.

Renewables and hydropower dominated the country’s energy mix in January, capturing a 53.6 percent share. Natural gas and lignite-generated electricity captured a 30.5 percent share.
