BESS Technical Due Diligence & Advisory

KRD Renewables provides independent BESS Technical Due Diligence in Poland and Central and Eastern Europe.

Our due diligence process combines technical, grid, permitting and environmental review to identify material project risks, test key assumptions and assess alignment with applicable project requirements.

A TDD service for standalone BESS projects is structured in two independent phases, which may be contracted separately or sequentially depending on transaction needs.
