The Slough Heat and Power Plant, located on the Slough Trading Estate in Berkshire, was acquired by SSE in January 2008.

In August 2018, decommissioning and demolition works began to facilitate the development of a new ~50MW energy-from-waste facility, known as Slough Multifuel, at the site.

Part of the existing Slough Heat and Power Plant remains operational and continues to supply energy, water and heat to local customers.

In April 2020, SSE Thermal entered into an agreement with Copenhagen Infrastructure Partners (CIP) to develop the new Slough Multifuel facility as a 50:50 joint venture.

The facility will produce electricity and heat through burning waste-derived fuels made from various sources of municipal solid waste, commercial and industrial waste, and waste wood.

Construction of Slough Multifuel, which commenced in May 2021, is being undertaken by specialist EPC contractor HZI. Construction is expected to take approximately three and a half years.

See below for latest construction update and Stage 2 Consultation.

Slough Multifuel Extension Project

The existing planning permission for the Project, granted by Slough Borough Council in May 2017, allows the Multifuel Plant to generate up to 50 megawatts (MW) of electricity. We are now seeking to increase the efficiency of the Plant so that it can generate up to 60 MW of electricity. Because we want to increase the generating capacity of the Multifuel Plant to more than 50 MW, we need to obtain development consent from the Secretary of State for Business, Energy and Industrial Strategy. Development consent is granted in the form of a Development Consent Order (DCO).

The application for development consent will be submitted to the Planning Inspectorate who will administer the process on behalf of the Secretary of State. Before an application for development consent can be submitted it is necessary to engage and consult with the local community, the local council and neighbouring councils and bodies such as the Environment Agency. The application needs to include a Consultation Report setting out how the comments received have been taken into account. The final decision on whether to grant a DCO is made by the Secretary of State. You can find out more about the DCO process on the Planning Inspectorate website.
