Utility-scale battery storage: Building the resilient grid of tomorrow, today

Storing renewable energy brings reliability, flexibility and resilience for today’s grid – and for the grid of the future. 

Electricity grid operators need to match supply with demand – nonstop. Battery energy storage is a technology that helps deliver on that critical responsibility by allowing electricity to be stored and delivered whenever and wherever customers need power most.

When paired with energy generated from renewable energy sources, battery storage can save consumers money, help increase the efficiency of the electric grid, reduce carbon emissions and air pollution and support good paying American jobs. Now, even during cloudy periods, day or night, energy providers can help manage the power supply by delivering stored, low-cost clean energy.


What are the advantages of energy storage?

Energy storage is key to unlocking our clean, reliable, and affordable energy future. With grid scale battery energy storage systems (BESS), we can increase renewable energy adoption, support decarbonization, boost our resilience against extreme weather events, and enhance grid reliability. Another key benefit of energy storage is its ability to reduce electricity costs by balancing supply and demand – storing energy when prices are low, and discharging it during peak periods when rates are higher.

Electricity cost reduction

Storing energy when electricity prices are low and then discharging when demand is high increases supply during peak periods as well as helps lower overall costs

Protection of productivity and critical services

During brief outages, storage helps businesses avoid costly disruptions and continue normal operations

Minimization of power outages

Storage increases grid flexibility and helps provide uninterrupted power for consumers, businesses, and other users

High energy density

Battery energy storage systems take up minimal space for the amount of power they release

A more reliable, resilient grid

Energy storage enhances reliability, ensuring the seamless delivery of electricity to consumers and businesses especially when they need it most

Increased viability of renewable energy

Energy storage enables powering the grid using low-cost renewables, even when the sun is down

Our policies and commitment to excellence

We are dedicated to making sure our energy storage projects are designed, constructed and operated to the highest possible standards.  

  • We monitor our energy storage systems 24/7

    We closely monitor our sites, 24/7, and are constantly running analytics and reporting to make sure that all our sites are performing optimally. 

  • We adhere to all relevant national and international standards

    Every Lightsource bp energy storage project is designed according to applicable local codes and standards such as International Fire Code (IFC), International Building Code (IBC), International Electrotechnical Commission (IEC), and National Fire Protection Association (NFPA).

  • We integrate extensive safety measures

    Typical safety features included in Lightsource bp energy storage projects include:

    • 24/7 monitoring including continuous monitoring of battery modules
    • Visual and audio alarm systems
    • Robust non-combustible enclosure design, including ability to withstand seismic activity, heavy weather and high winds
    • UL-rated battery enclosures that have completed rigorous safety testing
    • Emergency shutoff
    • Site level protection and monitoring including on-site personnel and command centers that continuously monitor the condition of every energy storage system enclosure
  • We are committed to recycling

    Lightsource bp is committed to reusing and recycling as much of our materials as possible, at the end of our projects and throughout their lifespan, as part of our global commitment to sustainability, reducing waste and creating a true circular economy. We were the first solar farm owner/operator to commit to reusing or recycling all end-of-life solar panels. Likewise, we are committed to recycling all end-of-life batteries.

  • We have a community-first approach

    Our dedicated Community Relations team engages with host communities throughout the entire project lifecycle – from the time we start planning a solar or energy storage project, through to construction and operations. Our community ambassadors are here to ensure they answer questions that community members may have, but more importantly to listen and afford the ability for communities to provide input.
