BESS Anthura Bleiswijk

Anthura has installed a battery energy storage system (BESS) in its own 10kV network. This energy storage system consists of interconnected batteries that store or supply power to the grid. It acts as a kind of buffer that can exploit volatility in energy markets to generate revenue.

Technical specifications

• Supplier: ProfiNRG
• Type: Huawei Smart String LUNA2000
• Power: 4.472 MW
• Storage capacity: 8.994 MWh 

Components:

• 2 battery containers of 4.47 MWh each
• 24 inverters (Smart PCS, 200

Each container contains 12 battery racks. Each rack is connected to one inverter that converts direct current (DC) to alternating current (AC) of 800V. This current passes through the transformer to our 10 kV network.

Why a BESS?

A BESS (Battery Energy Storage System) makes our energy system more flexible by allowing us to store generated power from solar panels and CHP plants. This allows us to optimise our own energy consumption and use energy more flexibly. Moreover, the battery offers opportunities to participate in energy markets such as imbalance market, day-ahead market and intraday market. Anthura participates in balancing services both nationally for TenneT through the aFRR (regulating power) and locally for Stedin through the GOPACS. So this installation not only helps reduce costs but also relieves the electricity grid.

From idea to realisation

It started with a business case developed through simulation by Emmett Green. The project turned out to be a profitable investment. This was followed by an extensive tender and the choice of ProfiNRG to supply Anthura with a Huawei system. The installation required no permit, but a lot of preparation:

• Technical: Installation of the foundation, transformer, battery containers, inverters, cables and connection to existing installations.
• Attunements: DNO Energy (control box), Emmett Green (energy management system), fire brigade and insurer.
• Administrative: Submit ESMD forms to Stedin (grid operator), apply for EAI subsidy, sign up for aFRR via DNO, adjust grid configuration (battery separately at a secondary allocation point), enter into energy contracts and define strategy for deployment in electricity markets.

In total, the project took about 18 months from initial simulation to going live. The delivery time of the battery containers inverters about 5 months from order. From then on, another month before the system went live.

The next step

The hardware is in place, but the real challenge starts now: optimising strategy and control. How do we make the smartest use of the battery for storage, supply and emergency power in combination with all the different energy and balancing markets? This is something we will explore further in the coming period.
