JV Portfolio: Dev-to-Sell

We co-develop BESS projects in JV structure with IPPs, funds and utilities,
delivering ready-to-build assets for resell or joint operations

A local partner you can trust

Our JV pipeline spans projects from early stages to RTB, developed for JV partners looking to enter the Polish BESS market.

Two ways to develop with us

JV Co-development

We co-develop projects from initial screening to ready-to-build, leading the development process while our partner provides capital and participates at agreed decision points.

RtB Acquisition

We acquire Ready-to-Build projects, fully permitted and grid-connected.

How We Develop

How We Develop
  • Land Selection
  • Grid Analysis
  • Permitting and Grid Connections
  • EPC Selection
  • Technical Design
  • Project Financing
  • Route to Market
  • Construction
  • Certification with Operators

We screen land for the right site conditions

We combine geospatial and infrastructure data to screen land parcels, assess grid capacity, and map permitting pathways before a site enters development.

From Investment Decision to Construction Start

From Ready to Build, the project advances through EPC selection, technical design, financing, and route to market — leading directly to Notice to Proceed.

From Construction Start to Full Operation

Following Notice to Proceed, the project moves into its build-out phase — construction is completed and the plant undergoes certification with grid operators, marking the final step before reaching Commercial Operation.

The process behind the asset

Data-driven development

The same engine we use for our own portfolio

Proprietary screening and AI-driven pipelines identify and develop the strongest opportunities — the same process behind every project we run ourselves.

  • Data-heavy screening across the whole market
  • Proprietary AI pipelines, not manual sourcing
  • Same process behind our own portfolio

Local market expertise

Our DSO/DNO relationships and Polish market knowledge

Established relationships and on-the-ground knowledge move projects efficiently towards ready-to-build, with a faster, cleaner path than sourcing cold.

  • Established DSO/DNO relationships
  • On-the-ground knowledge of the Polish market
  • Faster, cleaner path to ready-to-build

One process. Sharedat the right moments

  1. Develop

    We lead the development process. Our team screens, secures and de-risks each project end to end.

  2. Decide together

    At each key stage, both sides review the project and decide whether to continue, move towards ready-to-build, or pursue another path.

  3. Transfer

    Once the agreed stage is reached, the partner takes over the de-risked asset — or continues developing it with us.
