Unlike in the previous three years, for the grid development plans 2025, the four transmission system operators were asked to calculate six scenarios instead of four, comprising four scenarios using a ten year time frame and two scenarios projected to 2035. At the same time, the Renewable Energy Act, which had been amended in August 2014 was fully incorporated into the network calculations as a fundamental change to the basic framework conditions.
The TSOs presented the first drafts of the GDP and the O-GDP for public consultation on 30 October 2015; the second drafts were published at the end of February 2016.
On 8 June 2016, the German federal government reached an agreement on a draft law to amend the German Renewable Energy; this was passed by the upper and lower houses of the federal parliament on 8 July. In this context, as a result of the significant changes made to the parameters concerning energy policy, German legislative authorities decided not to proceed with the process of producing the Grid Development Plan Electricity 2025. The second draft of the Grid Development Plan 2025 was thus neither presented for public consultation nor was it approved by the German Federal Network Agency. In contrast, the second draft of the Offshore Grid Development Plan (O-GDP) 2025 was presented for public consultation between 14 June and 9 August 2016 along with the Federal Network Agency’s environmental report. The Federal Network Agency approved the O-GDP 2025 on 25 November 2016.
From the O-GDP 2030 (2017) onwards, the Offshore Grid Development Plan is to be replaced by the Offshore Area Development Plan, which will be produced by the Federal Maritime and Hydrographic Agency.
