Yn flaenorol, roedd busnesau ar Barc Ynni Baglan yn cael eu cyflenwad trydan drwy rwydwaith gwifrau preifat o orsaf bŵer nwy ar y safle. Ym mis Mawrth 2021, cafodd y cwmni a oedd yn berchen ar y rhwydwaith gwifrau preifat ei ddiddymu'n orfodol.
Businesses on Baglan Energy Park previously received their electricity supply via a private wire network from an on-site gas-fired power station. In March 2021, the company that owned the private wire network was placed into compulsory liquidation.
