Energy Storage Project Development
for Third Parties

Back to Grid develops energy storage projects on behalf of third parties: investors, developers, industrials, local authorities. Our starting point is not the land. It's the grid connection. We work back from the network to the site, not the other way round.

Grid Connection Is
the New Bottleneck

Grid connection has become the bottleneck of project development in France. Queues keep growing, S3REnR capacity is running out, and connection costs can make or break a business plan. We develop projects where the grid can actually accommodate them.

Three Ways to
Work With Us

01
Delegated Development

We carry the project on your behalf, from site identification through to ready-to-build. This is delegated project ownership: you remain the project owner, we run the day-to-day.

02
Owner's Engineering Support

You stay in control of the project. We bring the technical expertise and manage the studies, working alongside your teams.

03
Co-development

We bring the project, you bring the capital. A partnership model for investors who want access to an already qualified pipeline.

What We Actually Do

  • Identification and scoring of grid connection points (HV substations, DSO HV/MV transformer capacity (Enedis & ELDs), S3REnR capacity, connection queues)
  • Technical and economic feasibility studies
  • Sizing and electrical architecture (BESS, PV, wind, data centers)
  • Connection requests, PTF, connection agreements, dialogue with RTE and Enedis
  • Management of external studies and coordination of engineering firms
  • Drafting of regulatory files and follow-up of the review process
  • Technical specifications, EPC tender management, offer analysis
  • EMS, PPC and PCS design reviews against grid operator requirements

Owner's Engineers
Before Developers

We are Owner's Engineers before we are developers. We know what breaks a project during construction and commissioning, so we anticipate it during development. Our projects reach construction with an electrical architecture and control logic already validated against the grid code.
