A proposal by RAE, the Regulatory Authority for Energy, for a revision of renewable energy production licenses on non-interconnected island units, the objective being to increase energy storage levels, has been been met favorably by HEDNO, the Hellenic Electricity Distribution Network Operator.

Such a development would increase RES penetration on the Greek islands but needs to be carefully designed, the operator noted in a public consultation procedure staged by RAE on the matter.

HEDNO also noted that a new study will need to be conducted to examine capacity limits for all RES technologies based on new market data.

In addition, the operator pointed out that adequate infrastructure to service monitoring and management issues, currently being developed, will need to be completed by 2020.
