Case Study: Southampton City Council Clean Growth Fund

Southampton City Council building

The Energy Hub team supported Southampton City Council as it developed a business case for a Clean Growth Fund to finance the retrofit its non-residential properties. The project will save money for the Council to reinvest in local services as well as reducing carbon emissions.

Background

In June 2019 Southampton City Council launched its Green City Charter with the goal that the Council would be carbon neutral by 2030.

To help achieve this, the Council developed plans for a Clean Growth Fund to provide funding to make all its non-residential buildings and street lighting carbon neutral.

The programme has the potential to deliver cost savings and annual CO2 savings of around 7,000 tonnes across the 130 buildings involved.

Our role

The South West Energy Hub supported the Council to develop a business case for the first phase of the Clean Growth Fund to retrofit three of its buildings. This included researching and advising on the commercial opportunities for generating electricity and income from PV panels and batteries mounted on the buildings. This project identified innovative models for supplying electricity building to building.

Location

This project includes all the Council’s non-domestic properties, such as offices, depots, car parks and schools across the City of Southampton.

Technology

This project is being delivered through a mix of energy efficiency improvements, onsite renewable energy generation and battery storage.

Financing and ownership 

The improvements and installations are being funded by a £20M Clean Growth Fund operated by Southampton City Council.

The Clean Growth Fund draws together funding from a range of financing sources including Council funds, Salix Finance, grants and other sources.
