## Description
The procurement proposes appointing Wattserve Itchen Limited ("Supplier") to provide electricity to Portsmouth Water Limited ("PW"), integrating both new renewable generation and existing solar assets on PW's premises at River Itchen Water Treatment Works (the "PW Premises"). The Supplier will install, operate and own new solar PV and battery storage assets to supplement the electricity supplied to PW from the existing solar assets.
Brockhampton Solutions Limited ("BSL") currently owns existing solar assets on PW's Premises and supplies electricity to PW under a power purchase agreement. In order to ensure the new arrangements align with BSL's existing supply arrangement, PW and the Supplier will coordinate with BSL to continue the supply of electricity from BSL's existing assets to PW under the existing power purchase agreement. The Supplier will supplement any shortfall of electricity needed by PW on the PW Premises.
PW, as the occupier of the PW Premises, will consume the electricity supplied under this integrated arrangement and provide access for the installation and operation of the Supplier's assets. The combined approach ensures PW's electricity needs are met through a mix of the Supplier's new generation, BSL's existing solar assets, and grid supply where required.
This arrangement establishes the roles and interactions between PW, BSL, and the Supplier, supporting an efficient, coordinated electricity supply while maintaining continuity with existing solar infrastructure.
