Grid sufficiency ensured despite today’s heightened demand

Virtually all of the country’s power generating facilities, including RES units, have been called into action today by power grid operator IPTO to cover heightened demand, expected to peak at 8,978 MW at 6.30pm, as a result of the sharp temperature drop around the country.

Power utility PPC’s lignite-fired power stations Agios Dimitrios III and IV, Kardia III and IV, and Meliti, will operate as the fundamental generation facilities.

Natural gas-fired power stations – PPC’s Aliveri V and Megalopoli V; Elpedison’s units in Thessaloniki and Thisvi; as well as Protergia and Korinthos Power units – will be on stand-by to contribute if demand fluctuations require their grid input.

RES output, expected to reach 58.135 GWh, will cover approximately 34 percent of the day’s overall demand.

As for prices, the grid entry of many lignite-fired power stations has pushed up clearing prices at the energy exchange, anticipated to reach €62.24/MWh today from €53.58/MWh yesterday and €41.70/MWh two days ago.

IPTO has asked energy-intensive producers to limit their energy consumption until the extreme weather conditions have elapsed, unofficially bringing into play the demand response mechanism. Cement and steel producers are among the energy-intensive producers voluntarily cutting back on energy consumption to help prevent any grid insufficiencies.

Electricity demand down 12.6% in April, industrial use slumps 23.6%

Electricity demand slumped 12.6 percent in April compared to the same month a year earlier, the biggest drop registered by high-voltage industrial consumers, forced to suspend or restrict output during the lockdown, power grid operator IPTO’s monthly report has shown.

Industrial electricity consumption in April fell sharply by 23.6 percent, the IPTO report showed.

The drop in electricity consumption linked to mining activity was even sharper, falling 55.5 percent in April. Besides the lockdown, this drop was also attributed to significant operational restrictions implemented at power utility PPC’s lignite-fired power plants.

Electricity generation in April fell by 3.2 percent, to 2,893 GWh compared to 2,990 during the same month a year earlier, according to the data.

This reduction was mild compared to major shifts observed in sources of generation. Lignite-based generation fell by 62.7 percent year-on-year, confirming, most emphatically, the commencement of PPC’s decarbonization effort.

High costs for lignite-based generation severely reduced the operational time of PPC’s lignite-fired power plants, limiting lignite’s share of the electricity production mix to just 10 percent in April.

On the contrary, the production share of interconnected RES facilities, benefiting from favorable conditions, rose sharply by 33.9 percent, year-on-year, to capture a market-leading 36 percent share of overall electricity generation in April.

Natural gas-fired power plants followed with a 30 percent share following an 11 percent year-on-year rise in output.

Electricity imports (grid interconnections) contributed 18 percent, while hydropower facilities increased their output by 19.8 percent to capture a 6 percent share in April.

PPC provided 951 GWh, or 56.6 percent of the production, while independent producers covered 43.4 percent.

Among the independent producers, Mytilineos led the way with 228.1 GWh, followed by Elpedison (210.4 GWh), Korinthos Power (154.1 GWh) and Heron II (136.3 GWh).

The IPTO data on generation highlights an increasing shift towards cleaner energy sources.
