According to the latest monthly data for the interconnected electricity network from ADMIE (August 2021):
After the dominance of renewables (RES) over fossil fuels during the colder months of 2021 in the Greek electricity mix, fossil fuels take over during the summer producing higher share of the electricity demand. This shift is mainly caused by the major increase in electricity demand compared both to the winter period and the same period in 2020. More specifically, electricity demand during the summer months of 2021 increased by 13% compared to same period in 2020.
The result of the summer months is reflected also in the last 8 months of 2021, where fossil fuels are leading in production over renewables and large hydro, by a gap that has decreased significantly compared to 2020.
Electricity production from renewables (excluding large hydro) in August (1386 GWh) remained in relatively high levels, reduced compared to July, but marginally higher compared to the average of the previous months of 2021 (1384 GWh).
In August, lignite use increased achieving the second highest monthly production for 2021 after that of March. Thus, after 7 consecutive months where the lignite production was cumulatively lower than that of 2020, lignite contribution during the first 8 months of 2021 showed a slight increase compared to the corresponding period in 2020.
Overall, for the first 8 months of 2021, renewables and large hydro had a share of 42%, compared to 37% of fossil gas, 11% of lignite and 10% of net imports.
Compared to the first 8 months of 2020, RES (excluding large hydro) still have a higher percentage increase compared to fossil fuels, despite the significant increase of fossil gas and the smaller increase of lignite.
Finally, the changes compared to the first 8 months of 2020 were as follows:
Fossil Gas: +14.4
Large Hydro: +83.6%
Net imports: -50.4%
