Paramount resort developers have warned plans to build a £100 million renewable energy plant in Swanscombe could prejudice the planned £3.2 billion theme park, hotels and roads.

London Resort Company Holdings (LRCH) has called on Communities Secretary Greg Clark to reject a proposal by Teal Energy to build the plant in Manor Way.

Their intervention comes less than a week before the start of a public inquiry to determine the application, five years after it was first submitted.

The plant will produce renewable energy from non-recyclable commercial waste, enough to generate electricity to power 45,000 homes and London Paramount, although the resort is against the scheme.

Although approved by Kent County Council, the firm has received widespread opposition from both Gravesham and Dartford councils, businesses and neighbours.

Paramount developers are the latest to urge the government to throw out the plans.

This week, project managers announced the purchase of 18 acres of land as they continue to take control of the area needed to build the resort on the Swanscombe Peninsula in time for its planned opening in 2020.

Detailed plans unveiled at a public exhibition this year revealed a number of themed zones at the 288-acre site including Port Plaza, Paramount Port Bay, Adventure Isle and a Myths and Legends Castle, according to documents.

LRCH director David Testa said: “With emerging proposals for the Garden City and the London Paramount Entertainment Resort application to be submitted later this year, it is simply not the time for piecemeal decision-making.

“The planning position has changed considerably since the Teal application was submitted in June 2013.

“London Paramount, as the UK’s largest leisure regeneration project must be a serious consideration.

“The prejudice to the delivery of the massive regeneration benefits is real and significant – we sincerely hope the Secretary of State rejects this application.”

Politicians have admitted they are worried about the impact the energy firm could have on the development if it is given the green light.

Dartford MP Gareth Johnson said: “I still feel this is the wrong location for a waste to energy plant.

“I accept the need for diversity in energy production but I don’t believe it’s in the interest of Swanscombe to have a power plant situated there.

“With the right infrastructure the Paramount theme park could be a huge positive for the local area with the creation of thousands of jobs and leisure facilities.”

A Teal Energy spokesman said: “The Teal application is fully compliant with all the strategic plans for the regeneration if the local area.

“Kent have stated that even in light of the formation of the Ebbsfleet Garden City corporation and the proposals from LRCH they still recommend and support the Teal Energy proposals.

“It is nonsense to suggest that we would prejudice the redevelopment in the area. The scheme is design to be a key part of the infrastructure.

“Teal Energy invited LRCH to discuss their concerns at a very early stage in their planning. LRCH refused to enter into any meaningful discussions including ones sponsored by Kent County Council.

"To suggest that we are incompatible is simple not true but simple bluster on the part of LRCH.”

The application was called in by the then Secretary of State Eric Pickles and is due to be heard at the Mercure Maidstone Great Danes Hotel in Hollingbourne on Tuesday.
