Fire commander Mark Watson said: "After the area was cleared, fire service personnel, along with on-site safety personnel, inspected the area and we believed the cause of the ruptured steam main to be accidental.
"It's not 100% clear at this stage - there will be further investigations carried out by on-site safety personnel."
The heat, power and biomass power plant was built on a 10-acre green field site near Derry Port in 2014.
It houses boiler and turbine buildings, a 33kv substation and storage for a range of equipment, as well as stack, transformers, conveyors, fans and silencers.
