Romania produces a surplus of energy, but it lacks storage capacities, while Bulgaria is investing heavily in batteries to monetize cheap energy.

While Romania boasts an increase in energy production from renewable sources, Bulgaria has understood the importance of energy storage. Ilie Bolojan emphasized that Romania produces a surplus of energy, especially at noon, but lacks sufficient storage capacity, which leads to low prices. Bulgaria, on the other hand, has invested in battery systems, already having over 2 GW of total power and nearly 8 GWh of storage capacity.

These investments allow them to buy cheap energy from Romania and resell it in the evening when prices rise. For example, on April 29, Bulgaria stored the surplus energy while Romania sold it cheaply. Criticism of the management of Hidroelectrica highlights that, without storage, Romania is missing economic opportunities, and the Bulgarians are benefiting from this situation. Investments in storage are essential to avoid losses and ensure lower prices for consumers.
