Bulgaria’s Ministry of Energy has launched two tenders to add 1,425MW of renewable power generation to the grid and 350MW of battery energy storage system (BESS) projects.

The ministry said the main objective of the investment, totalling BGN535.1 million (US$298.2 million), is to increase the share of clean energy in Bulgaria by supporting the construction and integration of renewables into the grid.

With a budget of BGN107.6 million, the first tender will finance the construction of solar and wind projects and co-located BESS with an installed capacity of 200kW to 2MW. In this tender, a minimum of 200MW of production capacity from renewables in combination with a minimum of 100MW of BESS will be built. The maximum amount of financing for a project is up to BGN35.9 million.

The financing will cover up to 50% of the eligible costs but not more than BGN1.08 million per 1MW of installed BESS capacity.
