Wholesale prices driven higher by heatwave, lignite units enter

The heightened electricity demand prompted by the country’s ongoing heatwave is applying intense pressure on wholesale price levels. Given today’s grid requirements, expected to exceed 8 GW, the clearing price at the energy exchange is seen rising to over 100 euros for 16 hours, peaking at 9pm at a price level of €127.82/MWh.

According to a power grid operator IPTO forecast, the system’s demand peak is expected to exceed 8 GW for a three-hour period, reaching as high as 8,108 MW. Overall demand today is seen totaling 156,115 MWh.

In order to cover the grid’s electricity needs for today, IPTO, in addition to the natural gas-fired power stations operated by power utility PPC and independent players, has also recruited four PPC lignite-fired power stations, these being Agios Dimitrios I, II and IV and Meliti.

The RES sector is expected to cover 27,540 MWh of total demand, while natural gas-fired power stations and hydropower units are seen contributing 99,651 MWh and 10,449 MWh, respectively.

As for the natural gas-fired power stations recruited for today’s grid needs, the list is comprised of PPC’s Aliveri V, Lavrio IV and V, Komotini and Megalopoli V, as well as the independent units Heron, Elpedison Thessaloniki, Elpedison Thisvi, Protergia and Korinthos Power.
