The Welsh Government has spent millions maintaining and reconnecting power to Baglan Energy Park since the collapse of its power station.
The total cost to the Welsh Government has reached £6m to maintain supply and set up a new electricity network at the 180-acre park based in Port Talbot after businesses faced having their power supply cut off.
Baglan Operations, which was the park's sole electricity supplier via a private wire network, went into compulsory liquidation in March last year.
