Six European energy trade groups have come together to raise concerns over changes to the draft network code on requirements for grid connection.

The changes have been drawn up by the European transmission operators body ENTSO-E and were last week submitted to the EU’s energy regulatory agency ACER.

But the six trade associations believe the changes show a “lack of vision on how the power system will be operated” and have written a joint letter to ACER to ask for more time to review the proposed alterations.

ACER is due to publish its ‘reasoned opinion’ on the new code in October.

In their letter to ACER director Alberto Pototschnig, the six groups – Eurelectric, VGB Powertech, EWEA, EPIA, Geode and Cedec – state that the draft code is missing cost-benefit analysis and also puts forward an “unbalanced allocation of responsibilities and uncertainty surrounding possible retroactive application”.
