The European Union Agency for the Cooperation of Energy Regulators (ACER) publishes today two decisions in line with the EU Regulation establishing a Guideline on Electricity Balancing, aiming to integrate the EU balancing markets.
The first decision regards the methodology establishing a list of standard products for balancing capacity for frequency restoration reserves and replacement reserves. The methodology provides the rules for an efficient exchange, sharing and procurement of reserves on a cross-border basis in Europe.
The second decision concerns the methodology establishing a co-optimised allocation process of cross-zonal capacity for the exchange of balancing capacity or sharing of reserves, which should lead to an optimised allocation of cross-zonal capacities to the day-ahead energy or balancing capacity markets and therefore to maximise possible welfare gains.
