The Agency has recently published two opinions on electricity network development plans, one on the draft Union-wide Ten-Year Network Development Plan (TYNDP 2016) and another one regarding its consistency with the national network development plans. ACER finds the draft TYNDP 2016 prepared by ENTSO-E has improved when compared with previous plans, but it also identifies some shortcomings. Among them, insufficient alignment with the national network development plans.
ACER Opinion on draft Union-wide Ten-Year Network Development Plan 2016
The ACER Opinion on the draft TYNDP 2016 considers that the plan has improved in identifying the economic-efficient target capacities at 10 boundaries of the European system where power exchange bottlenecks were identified, corresponding to more than 30 individual borders. ACER also finds the scenario development included in the plan better prepared and explained. It also praises the classification of projects into “mid-term”, “long-term” or “future projects” categories, reflecting different advancement level and implementation dates, and the analysis of a mid-term study horizon for 2020 in addition to the one for 2030.
Suggested improvements for the plan at EU level include:
ACER opinion on the consistency of the Union-wide and the national network development plans
ACER has also published an Opinion on electricity projects in the national network development plans (NDPs) and their consistency with the project clusters in the TYNDP 2016.
The Agency notes that 33% of the national parts of the TYNDP 2016 clusters are not included in the respective NDPs, while an additional 4% are included only partially. Further, the Agency identified a few projects which are deemed by the relevant NRA as having cross-border relevance, but do not appear in the TYNDP 2016. This mismatch between the plans has significantly increased compared to previous years. The most frequent reason for this mismatch is that the commissioning date of the cluster or part of it is beyond the time horizon of the NDP, followed by reasons of non-sufficient advancement and lack of confirmation of the necessity of the project.
The Agency raises concerns about the credibility and feasibility of many clusters included in the “future project” category (projects which are still “under consideration” and/or expected to be commissioned beyond more than 10 years). This category constitutes the vast majority (71%) of the absent national parts and corresponds to about 40% of TYNDP clusters and more than half of the TYNDP expected investment costs (78 billion Euro out of a total around 150 billion Euro).
