Extraordinary conditions push SMP as high as €105 per MWh

Extraordinary conditions resulting from coinciding temporary closures of various power facilities, both in Greece and abroad, have pushed up the System Marginal Price, or wholesale electricity, to levels of as much as 105 euros per MWh, as was the case yesterday.

Four domestic gas-fired power stations – Enthes (Elpedison), Heron CC, Lavrio IV and Protergia – were out of order yesterday, for different reasons.

Problems beyond the Greek border have made matters worse. Bulgaria’s 1,000-MW Kozloduy nuclear power plant is currently out of order. The Greek-Bulgarian line serves as a transit route towards North Macedonia as a line linking Bulgaria and North Macedonia is out of order. So, too, is a line linking Greece with Italy.

Power stations that rarely operate, such as an open-cycle Heron unit, needed to be called into action as a result of the problems on these various fronts. Their necessary contributions pushed the SMP to far higher levels.

Three power utility PPC lignite-fired power stations, Agios Dimitrios II and III and Melitis, along with PPC’s gas-fired power stations Aliveri V, Lavrio V, Komotini, Megalopoli V, as well as units run by the independent energy firms Heron, Thisvi and Corinth Power, all needed to be called into action to cover the grid’s needs.

The market appears to have normalized for today. SMP levels are down to relatively satisfactory levels, averaging 44.49 euros per MWh, primarily as a result of significant RES contributions, covering more than 50 percent of the overall demand, 123.993 GWh.

The lignite-fired power stations used yesterday – Agios Dimitrios II and III and Melitis – will remain closed today.

Grid prepared for demand peak of first heatwave this summer

Given the day-ahead market’s indications, the country’s first heatwave of this summer, expected to increase temperatures to levels of between 37 and 38 degrees Celsius today and tomorrow, should not cause any problems for the grid.

The system is prepared for daily demand levels of 150,760 MWh at a System Marginal Price (SMP), or wholesale price, of 73.549 euros per MWh.

Renewable energy is programmed to cover 21,584 MWh of daily demand and hydropower facilities a further 8,156 MWh.

As for the country’s lignite-fired power stations, power utility PPC’s Kardia II, III and IV, Agios Dimitrios III and IV and Megalopoli III and IV will all be called into action.

So, too, will gas-fueled power stations operated by PPC and private-sector electricity producers (Aliveri V, Lavrio IV and V, Megalopoli V, Heron, ENTHES, Protergia, Corinth Power).

Electricity exports totaling 21,350 MWh have also been planned. Demand is forecast to peak at 2pm, reaching a level of 7,622 MW.

In a statement released yesterday, Greek gas utility DEPA ascertained the country’s gas needs will be covered this summer, as will supply needs for customers in Greece and Bulgaria.

Total gas demand in Greece last year between June 15 and August 15 reached 8.1 TWh and is expected to rise to 9.2 TWh for the equivalent period this summer, according to DEPA.

Gas grid operator DESFA’s incoming LNG shipments for this period this summer will amount to 7.3 TWh, dramatically up from a 2.4 TWh total unloaded at the Revythoussa terminal on the islet off Athens during the summer period last year, according to the operator.
