This model can be enacted by local authorities as follows:

• Local authority designs, builds and commissions solar, storage and EV charging assets at a site.
• Solar energy may be used to provide renewable electricity to the site (if there is existing demand such as a building), to charge batteries and/or to provide EV charging services
• If EV charging points are made available to the public, a billing solution will be required (this is discussed further in Section 6. Feasibility).
• The local authority may generate additional revenue from exported energy from battery storage

This will require an additional commercial arrangement.

This model can be operationalised using two approaches:

1. Utilising public car parking and putting solar over the top
2. Providing EV charging services, integrated with solar and storage at the site

• Requires an off-taker of sufficient size to make business case stack up
• A solution will be required to bill EV users, most likely through a partner
• An export connection required for any power not used on site and where storage is being used for flexibility services
• More ambitious “charging hub” projects being explored by Dundee, Oxford and West Midlands Combined Authority

Key Benefits

Financial and CO2

• Value is dependent on utilisation of EV chargers and battery
• More EVs and reduced costs of storage will increase value in future

Other Benefits

• Accelerating roll out of Net Zero by integrating solar and EV charging
• Improved access to EV charging
• Local skills and jobs
• Improved air quality and impact on health

Risks and Considerations

• Financial uncertainty – not a lot of real world data available
• Requires a number of partners to maximise value (aggregator, charge point operator)
• More technically complex to design and manage • Could be combined with business case to electrify public sector fleets
• Very scalable – site capacity could be increased in future and business case will improve over time
