The energy transition needs storage

Germany is expanding wind and solar at record pace — but without storage, their energy is lost. Grid-connected battery storage closes exactly this gap.

150+ MWh portfolio in Germany

Selected projects

Co-Location Potential

One grid connection, twice the value.

Co-location combines battery storage and photovoltaics or wind at the shared grid connection point. The storage system buffers generation peaks that would otherwise be curtailed and markets them with a time shift. This lowers the proportional grid costs and maximizes the yield per site.

1

Share infrastructure

Grid connection, transformer station and connection point are used jointly — one connection instead of two.

2

Avoid curtailment

Surplus PV power is stored instead of discarded and marketed when prices are high.

3

Stack revenues

PV direct marketing plus storage arbitrage and ancillary services — multiple revenue streams per site.

Frequently asked questions

Answers for landowners, municipalities, utilities and investors.

What is a grid-connected battery storage system?
A grid-connected battery storage system (BESS) is a stationary facility that draws power from the public grid, stores it and feeds it back when needed. Unlike home storage, these systems operate at the megawatt scale and contribute to grid stability by balancing generation and consumption peaks.
What does co-location mean?
Co-location refers to the joint operation of a battery storage system and a renewable energy installation (wind and photovoltaics) at the same grid connection point. Surplus power is stored instead of curtailed and marketed with a time shift — lowering proportional grid costs and maximizing yield per site.
I own land — how does the collaboration work?
We assess location, grid connection and building rights free of charge and without obligation. If the site fits, we develop the project, secure the permits and build it. KW Ventures bears all costs for planning, construction and operation; you keep ownership and receive a long-term lease over 20+ years. Full decommissioning is contractually guaranteed.
What sites are suitable for battery storage?
Sites from approx. 1,000 sqm near substations or existing renewable energy installations are suitable. Since December 2025, battery storage above 1 MWh has been planning-privileged in non-urban areas (Section 35 BauGB), significantly accelerating permitting. We focus on Saxony, Saxony-Anhalt and Brandenburg.
What benefits does battery storage offer the local grid operator?
A storage system in the distribution grid absorbs feed-in peaks locally, reducing grid expansion and redispatch needs — Germany spent over EUR 3 billion on redispatch in 2025. The storage system also provides ancillary services such as primary (FCR) and secondary (aFRR) control reserve directly from the grid area.
How large is the demand for storage in Germany?
The Grid Development Plan estimates the need at 40 to 90 GW. As of May 2026, around 4.3 GWh of large-scale battery storage is installed — about 5 percent of demand. Deployment is accelerating: 842 MW were added in 2025, and in March 2026 more than 1 GWh was added in a single month.
What does the grid fee exemption mean for battery storage?
Under Section 118(6) EnWG, battery storage commissioned before August 2029 is exempt from grid fees for 20 years. In May 2026 the Federal Network Agency confirmed that grandfathering protection remains in place with no retroactive charges. After 2029 a moderate capacity charge of EUR 4 to 7 per kilowatt per year applies.
How does the new capacity market work?
The German Capacity Market Act (StromVKG), enacted in May 2026, introduces a capacity market in Germany for the first time. Battery storage can participate from the generation-capacity auction in May 2027 and receives payment for maintaining available capacity — independent of electricity trading revenues.
What is the maturity-based grid connection process?
Since April 2026, the four transmission system operators allocate grid connection capacity based on project maturity rather than first-come-first-served. Site security, permitting status, technical feasibility and system benefit are assessed — mature projects get priority. Over 9,700 projects are currently waiting for a grid connection.
What are flexible connection agreements (FCA)?
Flexible connection agreements are bilateral contracts between plant operators and grid operators that enable faster grid connection in exchange for accepting temporary feed-in curtailment. The Fachagentur Wind und Solar published a model contract in 2026; for battery storage, FCAs can shorten connection times by one to two years.
