Restack Energy
Solar repowering · Battery storage · Flexibility

More value from every grid connection you already have.

We assess ageing solar parks, repower them and add battery storage behind the existing connection. We bring the screening, the storage know-how, the commercial model and the financing structure, working alongside capital and trading partners.

Why now

The first generation of solar parks is due for its second life.

Ageing assets

Inverters reach end of life, modules degrade and subsidy periods run out. Many parks earn less every year.

Scarce connections

New grid capacity is hard to get. An existing connection is often the most valuable part of a park.

Midday prices under pressure

Solar output peaks when prices are lowest. Storage moves that energy to the hours when it is worth more.

Approach

Three layers of upgrade on one connection.

Each layer stacks on the one below. We screen every park for all three and only propose what the numbers support.

Site sheet · existing PV park MWp · MWh · kVA
Layer 3 · Flex

Battery storage and trading

A BESS behind the meter shifts output, captures trading revenue and makes full use of the connection.

Layer 2 · Repower

More generation, same connection

New, higher-yield equipment raises output within the existing grid capacity.

Layer 1 · Revamp

Restore performance

Replace failing inverters and components to bring the park back to spec.

How we work

From screening to a financed upgrade.

  1. Screen

    Fast assessment of solar and storage potential per asset: technical state, grid position, permits and revenue.

  2. Structure

    A business case per park and a portfolio structure that capital providers and trading partners can commit to.

  3. Deliver

    Procurement, repower, revamp, BESS integration and handover to operations and trading, with one party accountable.
