Campaigners battling against plans to install a controversial incinerator in Harlesden could soon claim a hard-fought victory following speculation that the proposals could be shelved.

A four chimney “energy recovery centre” planned by Clean Power Properties in Channel Gate Road is facing the axe because the site has now been earmarked for HS2.

The Times has seen an email from the Greater London Authority, which oversees transport, policing, economic development, and fire and emergency planning, the land would serve as a main tunnel bore site for the controversial £43billion railway project, which will deliver a high-speed railway between London, the Midlands and the North of England.

Residents from Brent and Ealing had united to oppose the plans, claiming it would increase air pollution and traffic volume.

They held a number of peaceful protests on the site and made a short film arguing why the incinerator should not be given the green light.

Ealing Council had initially recommended the plans were approved, subject to conditions, even though a report for planning officers by their own regulatory services stated the application should be refused.

However the decision was deferred in August and was due to be made on November 6.

The decision was shelved for a second time after the application was removed at the 11th hour, pending further reports.

Cllr Zaffar Van Kalwala, of Stonebridge ward, who lobbied against the controversial incinerator on behalf of local residents, said he was “absolutely delighted” with the development.

He added: “The incinerator would have had a terrible impact on our air quality and the health of local people.

“I hope now that we can move forward and make sure that we never face such a threat again.

“This decision is good for local residents, good for the economy and good for Brent.”

A GLA spokesman has confirmed that the site was being acquired for HS2.
