Polskie Sieci Elektroenergetyczne (PSE), as Poland’s transmission system operator, was the counterparty to the project’s grid connection agreement for Bałtyk 1. Electricity from Bałtyk 1 was planned to be delivered to the Krzemienica substation (under development by PSE) in the Redzikowo municipality, and the developers submitted an application to PSE to change the connection conditions to direct current (HVDC) technology.
