The Energy Community power system with currently planned investments until 2030 can integrate as much as 30 GW of variable renewables without additional investments into flexibility sources, a study published on Wednesday showed.

The study, prepared by Artelys and Trinomics consultancies, assessed the flexibility needs and options to balance each Energy Community contracting party’s power system on different time-scales (daily, weekly and annually) until 2030 and 2040 under different assumptions mainly linked to the speed of renewables uptake and level of market integration.

While it demonstrated no need for additional investments into flexibility sources until 2030 if variable renewables reach 30 GW, it noted that higher levels of wind and solar will require a more flexible power system to balance supply with demand.

However, investments will be substantially lower if existing cross-border infrastructure is better utilized and short-term electricity markets are operational and coupled with the EU, said the Vienna based body in its press release about the study.

The calculations done by the consultancies showed that annualised investment needs or costs between 2030 and 2040 where this pertains to additional flexibility sources will drop by as much as EUR 150m if organised day-ahead and intraday and balancing markets are coupled between the contracting parties and with the EU.

Market integration will also allow the absorption of an additional 5 TWh of yearly variable renewable production from the EU that would otherwise be curtailed, added the study.

“The energy transition is irreversible and today’s study shows that nothing should stand in the way of more renewables. Against the background of the energy crisis, we must look for cost-effective solutions to unlock higher renewables potential. Further electricity market integration is the clear way forward,” the head of the Energy Community Secretariat Artur Lorkowski was cited as saying in the statement.

The study concluded by setting forth policy and regulatory recommendations to minimize overall system costs, including on energy sector governance, electricity market design, renewable energy development and carbon pricing.

It also recommended that the contracting parties define a flexibility strategy as part of their National Energy and Climate Plans (NECPs).

The Energy Community transposes EU energy market rules to countries aspiring to join the bloc. Its contracting parties are Serbia, Bosnia and Herzegovina, North Macedonia, Kosovo, Albania and Montenegro in the Western Balkans and Black Sea countries Ukraine, Moldova and Georgia.
