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.
