The City of Edinburgh Council is seeking projects that combine onsite generation of renewable energy, battery storage and smart meters with innovative software systems to control everything.
It aims to have financially self-sustaining, closed-loop vehicle charging systems, with smart grid and vehicle-to-grid capabilities.
Projects are expected to range in size up to total costs of £20,000 per application and last up to six months.
A further £200,000 could also be available to prototype the best ideas in the second phase of the competition, according to Innovate UK.
Funding for the competition is being offered under the Small Business Research Initiative (SBRI) programme.
The deadline for registrations is 7th February 2018.
