GreenBattery storage developed, built and operated in-house
Stand-alone on the grid or directly at the data centre: Bright & Green is responsible for battery storage from securing the land and the grid connection through to day-to-day operation – in Germany and the Netherlands.
Development, construction and operation under one responsibility
Bright & Green does not hand a storage system over to a third-party operator. Those who secure the land and negotiate the grid connection subsequently run the plant as well.
- 01
Development
Securing the land, the grid connection, permits and a sizing derived from the intended use cases.
- 02
Construction
Procurement from the technology partners, installation, safety concept, commissioning and grid energisation.
- 03
Operation
Dispatch on market signals, monitoring, maintenance and market access for the whole service life.
What a storage system on the grid does
A stand-alone battery storage system is connected directly to a substation or to the grid connection of an industrial site. Its revenues derive from three applications that complement each other.
Grid services
Balancing power stabilises the grid within seconds. A storage system prequalified for that service is remunerated by the transmission system operator.
Arbitrage
The storage system charges during low-price hours and discharges during high-price hours. Dispatch follows the quotations on the day-ahead and intraday markets.
Peak load for industry
At the grid connection of an industrial site, the storage system caps load peaks and thereby reduces grid fees. The plant stands on the company premises and is operated by Bright & Green.
What a storage system at the data centre does
A data centre requires power in a quantity and steadiness that a grid connection alone does not assure. A battery storage system on site fulfils four functions at once.
Peak load
The storage system covers load peaks that would otherwise overload the grid connection or increase grid fees.
Grid services
When the data centre is not running at full load, the storage system provides flexibility to the grid and generates additional revenue.
Bridging
In the event of a fault, the storage system bridges the gap until the emergency power supply takes over or grid supply is restored.
Connection optimisation
With a storage system, a lower connection capacity is sufficient, which makes sites viable that would otherwise be ruled out.
From the site to commissioning
Six steps, all of them the responsibility of Bright & Green. The grid connection comes first, because without a connection agreement even the most suitable land cannot be built on.
Site and grid connection
Securing land near a substation, applying for the grid connection and obtaining the connection agreement from the grid operator.
Sizing
Deriving power, capacity and cycle life from the use cases the storage system will later serve.
Permits and safety
Building application, fire-protection and safety concept, and coordination with the municipality and the fire brigade.
Procurement and construction
Battery systems, inverters and transformers from the technology partners, installation by Bright & Green.
Commissioning
Functional testing, prequalification for grid services, grid energisation.
Operation and market access
Dispatch on market signals, continuous monitoring, maintenance and market access for the whole service life.
What keeps a storage system safe and profitable for years
The way a battery storage system is operated determines its safety and its profitability. Four tasks govern that across the whole service life.
Fire protection and safety concept
Distances, extinguishing concept, climate control and battery management are planned together rather than added afterwards.
Dispatch on market signals
The plant charges and discharges according to the configured use cases and the prices on the power markets.
Monitoring
Cell condition, temperatures and availability are monitored continuously. Deviations trigger maintenance before they reduce revenue.
Market access
Bright & Green is responsible for the connection to the balancing and intraday markets. The storage system serves several revenue streams at once.
Technology partners and certifications
Components and systems come from Siemens, KACO new energy, Gotion High-tech, BYD, and Kenter. Bright & Green is certified to ISO 9001, ISO 14001, VCA**, and SEI.
Three routes to a battery storage system
A plot of land, an investment or a data centre – each of these routes begins with a conversation about the grid connection.
You own land
Given proximity to a substation or high-voltage line and commercial zoning, Bright & Green will assess whether your land is suitable for storage – to lease or to buy.
You want to invest
Storage projects that businesses can invest in using the investment deduction under Section 7g of the German Income Tax Act. Not tax advice.
You are planning a data centre
Storage as a component of the energy concept – from connection optimisation to bridging.
What operators, investors and landowners ask us
The answers apply equally to stand-alone storage and to storage at the data centre.
