Battery Storage for the Public Sector

How can battery storage help my organisation?

If you have solar panels, battery storage allows you to capture more of your solar electricity.

The advantages of public sector battery storage include:

  • Capture and use more of your zero-cost solar electricity
  • Discharge stored solar electricity after the sun has gone down
  • Use to power buildings during the night and provide a reliable source of energy to EV charging ports
  • Top up your batteries with cheap, off-peak grid power
  • Emergency power in a power-cut
  • Generate revenue by supporting the grid
  • Benefit from a lower carbon footprint and support public sector decarbonisation goals

What are the benefits of installing battery storage in the public sector?

Installing battery storage brings about many benefits, enhancing the value and utility of renewable energy installations and ensuring the resilience and reliability of power supply. Here are some of the main benefits:

Energy Resilience and Reliability

Certain models of battery storage allow public sector buildings to have a backup energy source during grid outages.

Peak Shaving

Batteries can be charged during periods of low energy demand and discharged during peak demand, reducing peak energy consumption from the grid. This can lower electricity bills, especially in areas with demand-based or time-of-use pricing.

Integrating Renewable Energy

Batteries can store excess energy generated from renewable sources, like solar or wind, and release it when the sun isn’t shining or the wind isn’t blowing, ensuring a continuous power supply and maximising the utilisation of renewable resources.

Grid Stabilisation

Battery storage can provide frequency regulation, voltage support, and other grid services, helping to maintain the stability and reliability of the power grid.

Reduction in Carbon Emissions

By promoting the use of renewable energy and reducing reliance on fossil-fuel-based power during peak times, battery storage can help in significantly reducing carbon emissions.

Cost Savings

By utilising stored energy during peak pricing periods, public sector organisations can achieve significant savings on their energy bills. Additionally, some utilities may offer incentives or rebates for battery storage installations that provide grid services.

Load Shifting

Batteries can be used to shift energy consumption from one period to another. For instance, solar energy generated during the day can be stored and used during the night or on cloudy days.

Potential Revenue Streams

In some regions, public sector organisations can participate in demand response programs or energy markets, using their battery systems to sell stored energy or grid services.

Leading by Example

By adopting advanced technologies like battery storage, the public sector can set a precedent for sustainable and resilient energy practices, encouraging other sectors and the general public to follow suit.
