Marchwood Power Station is located on the site of a former oil-fired power station within Marchwood Industrial Park, adjacent to the River Test and overlooking the Port of Southampton. Since the late 1980s, the site had remained largely unused, apart from some vehicle storage. The site was selected primarily because of its previous use as a power station. The site is ideal as it offered:

- Efficient re-use of brownfield land rather than development of a greenfield site
- A location already designated for power station use in the local development plan
- Access to existing infrastructure from the previous power station
- Source of local, skilled labour during construction and operation

Combined cycle power plants are smaller in overall size than conventional thermal power plants and therefore require less space. Marchwood Power Station has been designed to minimize the visual impact on its surroundings. Physically, the plant comprises two elements: the main power station buildings and two 80m chimney stacks. There are no visible plumes from the plant’s chimney stacks under normal operations.

Particular attention has been paid to the visual appearance of all buildings and discreet colour schemes have been chosen to blend in with the surroundings. Appropriate landscaping helps to further reduce the visual impact.
