In addition to producing the grid development plans for 2024, in 2014 the four transmission system operators (TSOs) also carried out analyses of factors influencing grid development in order to investigate other aspects that may also have an effect on developing the grid. The first part of the report on factors influencing grid development, containing two of three factors, was published at the same time as the first drafts of the Grid Development Plan (GDP) and the Offshore Grid Development Plan (O-GDP) 2024. The second part of the analysis of factors influencing grid development was published on 14 July 2014.
Whilst preparing the second drafts of the GDP and the O-GDP, fundamental framework conditions for the energy industry were redefined by German legislative authorities as part of an amendment to the German Renewable Energy Act (Erneuerbare-Energien-Gesetz or EEG). The amended Renewable Energy Act came into effect on 1 August 2014. It contained a range of outline data that was relevant to the GDP 2024 in terms of the assumed levels of energy generation and consumption. As a result of this, the transmission system operators carried out a full recalculation of Scenario B 2024 within the approved scenario framework for the second draft of the GDP, which included appropriate adjustments to the regionalisation of renewable sources of energy. This scenario is thus referred to as Scenario B 2024* in the second draft of the GDP.
On 16 April 2014, the transmission system operators published the first drafts of the Grid Development Plan Electricity 2024, the Offshore Grid Development Plan 2024 and the first section of their analysis of factors influencing grid development. All stakeholders were able to submit responses to these drafts between 16 April and 28 May 2014. The TSOs published the second drafts on 4 November 2014 and presented these to the Federal Network Agency. The Federal Network Agency approved both the GDP and the O-GDP 2024 on 4 September 2015.
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.
