Provision of Power Purchase Agreement

Provides central government and the wider public sector access to renewable electricity by securing long-term contracts with suppliers.

Description

RM6289 helps you buy renewable electricity directly from specific energy projects. Either ones that already exist or new ones built specifically through this scheme. Use RM6289 to meet your organisation’s carbon net zero targets.

It includes:

  • group buying power:
    • bring customer needs together (aggregation) by purchasing energy in bulk
    • secure more competitive price
  • long-term agreements:
    • known as power purchase agreements (PPAs)
    • typically last between 5 and 15 years
    • you can finalise the exact length for your contract during the sign-up process
  • flexible contract types: the framework is primarily set up for pay-as-produced (meaning you pay for the electricity as it is generated)

Watch our introduction to power purchasing agreements webinar for more information.

How to buy

  1. Complete the PPA customer user agreement form located in the documents section and send it to info@gca.gov.uk where the buyer will receive a unique reference number for your project.
  2. Invite the suppliers to a pre-market engagement session to provide an overview of your requirements and to understand the suppliers’ current renewable energy pipeline and availability to build a new asset. Use this time to develop your understanding of the current energy market and specific PPA pricing models.
  3. Develop your specification and assessment criteria. Use the call-ff schedule guidance within the documents section to support the completion of the tender pack.
  4. Issue your invitation to tender through the our eSourcing portal or your procurement portal using the supplier contact details provided. The agreement allows for a further competition route to market only.
  5. Allow time for suppliers to submit a bid based on your requirements. The buyer should allow time for new build generation asset tenders.
  6. Evaluate supplier responses and issue the award notice to the successful bidder. Allow time for a standstill period. Email us the award notification form found in the document section to info@gca.gov.uk, quoting your unique reference number.
  7. Finalise the call-off contract schedules with the awarded supplier and ensure you arrange a sleeving agreement with an appropriate energy supply provider. This can be done through the RM6251 Supply of Energy 2 agreement if the buyer organisation is signed up to this framework.

Agreement pricing request

GCA does not hold any live PPA pricing. Pricing will be bespoke to each individual call-off. Buyers will need to understand the current energy market, including the relevant renewable generation asset pricing.
