Developer Northacre Renewable Energy is now waiting for a decision this month from Wiltshire Council for revised plans for the energy-from-waste facility after first gaining approval last year.
Revised planning was needed after NREL decided to drop use of a gasification technology at the proposed plant in favour of conventional grate technology for incinerating waste.
NREL, which is owned by UK power producer Bioenergy Infrastructure Group and Wiltshire-based waste management company The Hills Group, blamed Brexit and a lack of supply chain commitment for a fixed-price project using the system.
