The North London Waste Authority (NLWA) has backed an application to the Planning Inspectorate for a Development Consent Order for a replacement energy recovery facility at the Edmonton EcoPark.
The replacement facility would manage up to 700,000 tonnes of waste a year and could provide enough power for around 127,000 homes.
NLWA is also looking at diverting some of the energy to local homes and businesses via heat networks.
The Lee Valley Heat Network, which is a separate project that will be managed by Enfield Council, is aiming to use the available heat from the existing facility as soon as next year.
Members of the authority reviewed responses received during two phases of consultation between November 2014 and June 2015.
The authority says some suggestions received during the consultation have been accommodated, but others were rejected for a variety of reasons, including restrictions relating to the site and the site location.
The project will have an air-cooled system. The alternative of water, the current arrangement, was offered with the NLWA advising that the plume from the plant would be less obtrusive with air-cooled.
The viewing platform has been relocated to the south eastern edge of the facility and reduced in height by about seven metres to five or six metres.
