Potato Stores: Managing solar export for an agricultural site
How Open Power coordinated solar export arrangements for Potato Stores at Chapelbridge Farms, bringing together metering, contracting and renewal planning.
Potato Stores at Chapelbridge Farms is an agricultural site in Cambridgeshire with a 57 kW solar PV system and 47 kW of export capacity.
Open Power established the commercial export arrangement and subsequently progressed renewal planning as the existing contract approached expiry.

The requirement
A commercial arrangement for surplus solar electricity
The site needed an export agreement supported by the relevant export MPAN, metering and data arrangements. These elements needed to be coordinated so electricity exported from the site could be accounted for under the contract.

What Open Power handled
Site information review: We brought together the site’s solar capacity, export capacity, export MPAN and metering information to support the export arrangement.
Export contracting: We arranged the commercial agreement for the sale of surplus electricity and coordinated the contracting process.
Metering and data coordination: We coordinated the meter operator (MOP) and data arrangements with the requirements of the export agreement.
Renewal planning: As the existing contract approached expiry, we reviewed and progressed the next export arrangement.

The value
Making surplus generation commercially useful
For Potato Stores, the export side of the solar installation is not a small administrative add-on. A substantial proportion of the site's generating capacity can flow back to the grid. Open Power connects that surplus generation to a managed commercial process, while handling the metering, contracting and renewal requirements behind it.

The outcome
An export agreement in place, with renewal progressed
Potato Stores had an established commercial arrangement for its surplus solar electricity. Open Power also progressed the next arrangement ahead of the existing contract’s expiry.
