The contribution of renewable energy sources (RES) capacity to the interconnected system registered a rising trend in December, according to data provided by LAGIE, the Electricity Market Operator.

Wind-energy park capacity rose to 1,661.72 MW in December from 1,623.52 MW in November, a 38.2 MW increase, LAGIE figures showed.

Other RES sectors posted marginal changes. Small-scale hydropower plant capacity slipped slightly to 219.75 MW from 219.84 MW. On the contrary, biomass-biogass units increased their capacity to 47.44 MW from 47.19 MW in November. Combined heat and power (CHP) capacity remained steady at 99.07 MW.

Roof-mounted photovoltaic facilities, both interconnected and non-interconnected, registered slight capacity changes. Contracted photovoltaic capacity for interconnected systems was unchanged at 3,082 MW. Installed photovoltaic capacity in December increased to 2,085.31 MW from 2,079.70 MW in the previous month.

Interconnected roof-mounted photovoltaic systems registered a capacity increase to 350.36 MW in December from 350.32 MW in November. Non-interconnected roof-mounted photovoltaic capacity reached 24.24 MW in December from 24.20 MW in November.
