Why invest in battery energy storage project BESS Remscheid Luckhausen?

Strategic energy transition enabler: Germany’s energy transition requires flexible storage to stabilize the grid and maximize the use of solar and wind power. Battery Energy Storage Systems (BESS) like Remscheid Luckhausen play a central role in this transition. Located in North Rhine-Westphalia, the project helps integrating clean energy into the grid by storing surplus electricity and releasing it when needed - improving grid stability, reducing curtailment losses, and enabling higher renewable energy penetration.

Attractive returns with multiple revenue sources: The 5.15 MW / 12.2 MWh system will generate income through energy trading on Germany’s most relevant power markets, including the intraday, day-ahead, and balancing power markets (FCR, aFRR). These multiple streams of income are managed by one of Germany’s leading route-to-market providers for large-scale storage systems. Investors benefit from this active trading strategy and optimization, which allows for robust revenue generation and long-term resilience.

Backed by experienced partners: The project is being developed by Purpel Energy, a leading BESS developer and operator in Germany, and partly owned by Green FOX Energy. Purpel Energy oversees all stages of the project - from development and construction to asset management. The EPC and O&M services are handled by Intilion AG, a specialized German provider with more than 200 installed BESS units. Battery cells are supplied by CATL, a Tier 1 global manufacturer. The senior lender is one of Germany’s most established renewable energy banks.

Ready-to-build: All permits are in place, land has been purchased, and a binding grid connection agreement is secured. The project is ready for construction, with key suppliers and partners already in final contractual stages. With a construction duration of approximately 9 months, the system is expected to be operational in 2026.

Concrete environmental and economic impact: BESS Remscheid Luckhausen directly supports the decarbonization of Germany’s electricity system by reducing dependence on fossil fuels and lowering CO₂ emissions. It also contributes to price stability in electricity markets and provides local grid relief. The project aligns with the UN Sustainable Development Goals - specifically SDG 7 (Affordable and Clean Energy) and SDG 13 (Climate Action).

Overview

Introduction to the project

The problem

Germany’s energy grid faces a growing challenge: renewable energy sources like wind and solar generate electricity intermittently - only when the sun shines or the wind blows. This leads to frequent imbalances between supply and demand. When too much renewable energy is produced, the grid must curtail it - wasting clean electricity. When too little is available, fossil-fuel backup is still required. These fluctuations threaten both climate goals and grid stability.

The solution

BESS Remscheid Luckhausen is a standalone battery energy storage system (BESS) that solves this problem. Located in Remscheid, North Rhine-Westphalia, the system will store surplus energy and release it during peak demand or when the grid requires stabilization. It uses proven lithium iron phosphate battery technology and will be actively traded across Germany’s wholesale electricity and balancing power markets pursuing a multi-market strategy.

The project is designed to:

  • Store excess renewable energy instead of wasting it
  • Deliver power when demand peaks or supply drops
  • Support grid reliability and avoid blackouts
  • Reduce CO₂ emissions by replacing fossil-based reserve power
  • Generate income from day-ahead, intraday, FCR, and aFRR markets

Why North Rhine-Westphalia?

This state is one of Germany’s industrial powerhouses and energy transition focus areas. With strong grid connectivity and growing renewable generation, North Rhine-Westphalia is a prime location for grid-supportive battery storage. The project connects to the local grid via EWR GmbH, the municipal utility of Remscheid, under a secured grid connection agreement.

Icon project status

Status of the project: 

Ready-to-Build

All necessary permits and contracts are in place, the land has been purchased, and the grid connection is secured. Construction is expected to begin shortly after financing and to be completed within 9 to 12 months.

Electricity production:

5.15 MW of power and 12.2 MWh of usable storage capacity

The system enables real-time energy trading, frequency control, and grid balancing - ensuring high efficiency, market flexibility, and maximum impact.

How does energy storage work?

BESS Remscheid Luckhausen generates revenues by applying a multi-market strategy for settling generation and demand imbalances.

  1. Generating revenue and stability through balancing markets: The electricity grid needs to be balanced at all times, which means supply and demand have to be equal. Otherwise, in extreme scenarios, there will be a grid black-out. When one of the two (supply or demand) is larger than the other, a battery can solve this issue and will be paid for this by the Transmission System Operator. BESS Remscheid Luckhausen therefore participates in the so-called frequency control reserve (FCR) and automated frequency restoration reserve (aFRR), earning revenue by providing grid stability services.
  2. Generating revenue and balance through wholesale markets: When renewable power generation exceeds demand, prices for energy drop and the excess electricity can be stored in lithium iron phosphate batteries at low costs instead of being wasted. Later during the day, when renewable energy production is low, prices rise again and energy can be delivered when it is needed, sold at a higher price due to higher demand.

UPDATE 16.07.2025: Investor FAQ

Question:
Is the Invesdor bond subordinated or not?

Answer:
The Invesdor bond will be provided as a senior bond to Purpel Energy Projekt 1 Holding GmbH & Co. KG, which in turn lends the funds in form of a subordinated loan to the project SPV Purpel Energy Projekt 1 GmbH & Co. KG. Hence, the Invesdor funds will be subordinated (to the bank financing) in the project SPV and fully senior in the financed entity Purpel Energy Projekt 1 Holding GmbH & Co. KG. Furthermore, until the Invesdor bond is fully repaid including interest payments, there is a dividend lockup in place that prohibits Purpel Energy Projekt 1 Holding GmbH & Co. KG to pay dividends to its shareholders.
