July 18 (Renewables Now) - Wind and solar power generation within the control area of transmission system operator (TSO) 50Hertz Transmission GmbH in northeastern Germany increased to almost 28,000 GWh in the first half of 2019 as capacity grew.
Wind power alone was responsible for 21,591 GWh of the total, up from 16,562 GWh a year earlier, 50Hertz said on Wednesday, citing preliminary estimates. The increase in the eastern German states as well as in Berlin and Hamburg was registered thanks to newly-added capacity in the offshore sector.
The installed onshore and offshore wind capacity in the TSO’s area rose to 19,571 MW by the middle of this year from 18,856 MW a year before.
On the solar front, 50Hertz calculates that photovoltaic (PV) parks supplied 6,045 GWh, or 170 GWh more than in the first half of 2018. The installed solar capacity has expanded to 11,066 MW from 10,566 MW.
50Hertz said it managed to keep the costs for congestion management in the grid stable, even as renewables capacity and output grew.
50Hertz spent about EUR 13 million (USD 14.6m) for redispatch costs in the six months, made through interventions in the operation of conventional power plants. Costs for temporary curtailment of renewable energy sources, another congestion management measure, came at EUR 48 million.
