Battery Tenders

See open battery storage tenders and awarded contracts for the UK public sector.

Battery work covers standalone battery energy storage systems (BESS), battery packs paired with solar PV, and grid-connected storage sites, bought by councils, universities, sports clubs and energy authorities pursuing net zero targets.

There are 337 battery storage notices tracked to date, and 136 of those have reached award. Most projects bundle the battery with a solar PV installation rather than standing alone, so a single notice often covers design, supply and integration together.

Frequently asked questions

Frequently asked questions about battery storage system, bess, battery energy storage in the UK public sector.

  • How do I find battery storage tenders in the UK public sector?

    Search live procurement portals for BESS and battery energy storage notices, or work earlier: on Stotles you can see which buyers have flagged decarbonisation or net zero programmes and read the strategy documents behind a project before it reaches tender. Battery storage work is often bundled into a wider solar PV or energy programme, so a buyer's broader net zero plan is often a stronger signal than the notice itself.

  • How are battery storage contracts procured in the UK public sector?

    Mostly as design-and-build contracts that bundle the battery with a solar PV installation, rather than a standalone battery purchase. A single tender typically covers design, supply, installation, commissioning and sometimes ongoing maintenance. Larger grid-scale sites and multi-site framework programmes do appear, but most notices are project-specific rather than framework call-offs.

  • How many battery storage contracts have been awarded to date?

    136 of the 337 battery storage notices tracked to date have reached award. The rest are a mix of closed competitions and pre-tender activity, which reflects how many of these projects are still working through market engagement or design stages rather than being routine repeat purchases.

  • What CPV codes cover battery storage contracts?

    CPV 31422000 (Battery packs) is the code most specific to the physical battery, while 09330000 (Solar energy) appears widely because most battery storage projects are bundled with a solar PV installation. Neither code is unique to battery storage on its own, so the keyword filter, not the CPV code, does the real work of finding these notices.
