Grid De­vel­op­ment Plans
2030 (2017)

Amended in 2015, the German Energy Management Act stipulates that, starting with the 2017 version of the grid development plans for 2030, the transmission system operators no longer have to produce grid development plans every year, but a joint plan is to be produced on a biennial basis instead. In future, the Offshore Grid Development Plan (O-GDP) is to be replaced by the Offshore Area Development Plan, which will be produced by the Federal Maritime and Hydrographic Agency. By switching to a two-year cycle, the German legislative authorities have thus satisfied demands made by both the TSOs and numerous stakeholders, eliminating overlaps in time schedules between various different processes.

Another change to the grid development plans 2025 can also be seen in the number of scenarios. In contrast to the previous scenario framework, the 2017 version of the scenario framework 2030 contains four scenarios instead of six. Furthermore, for the first time, the scenarios no longer refer to a fixed time period of ten or twenty years. The specifications for the time frames used have also been adjusted in the German Energy Management Act and made more flexible in order to improve synchronisation between the grid development plans and the planning periods for European energy policy. In future, three scenarios are to cover a time period of between ten and a maximum of fifteen years. One scenario is to show developments for a time period of between fifteen and a maximum of twenty years.

On 31 January 2017, the transmission system operators published the first drafts of the plans and submitted these to the German Federal Network Agency. The public consultation period for both drafts was between 31 January and 28 February 2017. Following a content review of all responses received, the TSOs revised the first drafts accordingly. The resulting second drafts of the GDP and the O-GDP were published on 2 May and submitted to the Federal Network Agency.
