The latter will be done through a government home upgrade scheme, from which the council received £2.8m last month.
It means residents can get cheaper or free energy-saving upgrades, such as insulation, heat pumps and solar panels.
These will be delivered by E.ON and people who qualify can apply until March 2025, the council said.
An update on the partnership is set out in a report for a council meeting on 11 March.
Moving forward with retrofitting homes and electric vehicle charging services are two of its key focuses for 2024-25, the report said.
Solar panels in schools and cutting carbon emissions from council-owned buildings are other areas where it will aim to make progress.
The venture will last for 15 years and will bring up to £2 billion of private investment to the city, according to the council.
