Announcing Groundbreaking Solar Power Generation and Battery Storage Project at Lakeside North Harbor

The groundbreaking project will include roof-mounted solar photovoltaic panels in five buildings, one of the largest parking canopy solar panels in the UK and a large battery storage system. Work is expected to begin in the fall of 2022.

Across the UK, businesses and residents are seeing a steep rise in energy bills. However, this project will protect the commercial tenants of the Lakeside North Harbor offices from rising electricity costs.

Packages include:

  • 1,900 roof-mounted solar photovoltaic panels will be installed across the five buildings in Lakeside North Harbor
  • 8,000 additional photovoltaic solar panels will be installed above the existing car parks, forming solar canopies. These combined projects will have a total renewable electricity generation capacity of 4.5 megawatts (MW) and are expected to avoid the emission of 992 tonnes of carbon dioxide each year.
  • Installation of a number of electric vehicle (EV) charging points alongside the solar PV and battery project, as well as the infrastructure to install additional charging points as demand on site increases.
  • Installation of 2 MW batteries to allow storage and use of excess electricity during peak demand periods.

In order to maximize the electricity consumption generated by the photovoltaic solar panels, the 2 MW battery will have the capacity to store any excess electricity and instantly power approximately 2,000 homes. This means increased carbon emissions savings and further reductions in on-site electricity costs. The battery will also be used for “grid services”, which allow electricity to be stored or offloaded as needed by the national grid, to help balance other renewable generation sources and peak demand periods. demand for electricity.

The solar PV and battery installation is expected to begin in the fall of 2022 and be completed by the summer of 2023. When complete, the electricity produced by the solar PV system will total approximately 4.1 gigawatt hours (GWh) each year and will supply up to 38% of the site’s electricity needs, equivalent to the typical annual electricity consumption of more than 1,000 homes.

Commenting on the project, Cllr Kimberly Barrett, Cabinet Member for Climate Change and Environment, said:

“It’s great to see that we continue to build a portfolio of energy-saving projects across the city with the addition of this solar PV and battery in Lakeside. This will help support our tenants, businesses communities and residents at a time of rising energy bills The inclusion of new electric vehicle charging points will encourage and support more people to switch to electric vehicles as a reliable mode of transport, reducing their carbon footprint in times of climate emergency.

“Adding this project to our city-wide energy-saving initiatives and working alongside our major employers is a big step in the right direction toward our city-wide net-zero goal. city ​​by 2030.”

Simon Bateman, Lakeside Asset Manager, said:

“This is an incredible opportunity for Lakeside and its occupants to demonstrate their corporate social responsibility and environmental credentials. Not only will most of the running electricity used on site be generated on site, but occupants will also be able to save on spiraling electricity costs and reduce their carbon emissions while benefiting from Lakeside’s wellness offerings. . »

The work is the latest in a series of solar PV and battery projects managed by Portsmouth City Council’s in-house energy services team. The team also manages a major ongoing solar photovoltaic and battery project at Portsmouth International Port. The energy services team has installed more solar power in the council’s building portfolio than any other UK local authority, in schools, leisure centers and housing. The Lakeside project, when completed, will be the largest solar project ever undertaken by the council.
