Management of battery storage systems
With the growing share of renewable energies in electricity generation, battery storage systems are becoming increasingly important to the stability of energy networks.
As an operator of a battery storage system, you can contribute to the success of the energy revolution and at the same time benefit from lucrative revenues through trading. As an experienced player in flexibility markets, we ensure your investment is ideally managed.
Trading battery storage systems in solar parks as part of the EEG innovation tender
Supply and demand determine the electricity price on the electricity exchange every hour. Take advantage of the flexibility of your solar park with battery storage and benefit from feeding in the electricity produced at times of higher market prices. Our 24/7 trading desk forecasts your solar power production and takes over the trading management of your system. Both solar parks under direct marketing as part of the market premium and parks with fixed power purchase agreements (PPA) benefit from this optimised trading.
Trading stand-alone storage – a lucrative contribution to network stability
Stand-alone storage systems offer extremely good flexibility and significantly contribute to the stability of the energy networks: With market-oriented charging and discharging, they regulate, for example, network fluctuations and at the same time generate attractive revenues in flexibility markets. As part of the system-specific restrictions, our experienced 24/7 trading team will perform optimised trades across all relevant markets (spot markets and balancing energy markets), thereby, generating maximum revenues for the storage system.
Our services at a glance:
- Maximum revenues through optimised use across all relevant markets (spot markets and balanced energy markets)
- Trading at optimised energy prices through the use of our modelling and optimisation software, algorithm trading and automated trading strategies
- Market-specific management by our 24/7 trading desk
- Attractive, individual remuneration structures
- Simple connection of the storage via modern hardware and software to our virtual power plant
- Remote control unit as per the specifications of transmission system operators
FAQ for BESS
- What is the minimum-sized system that BayWa r.e. will take over for trading storage facilities?
We market battery storage systems from 2 MW / 2 MWh.
- What technical requirements must my BESS meet?
The operator of the BESS must ensure that the technical restrictions, such as a minimum or maximum state of charge (min. or max. SOC), can be met by the battery system. In addition, precautions must be taken to ensure that the storage system is always monitored by the operator’s technical management team and that we are notified of any abnormalities which have an influence on performance and availability at the earliest possible opportunity.
- How is the connection to the virtual power plant of BayWa r.e. made?
The operator of the BESS must ensure that the technical restrictions, such as a minimum or maximum state of charge (min. or max. SOC), can be met by the battery system. In addition, precautions must be taken to ensure that the storage system is always monitored by the operator’s technical management team and that we are notified of any abnormalities which have an influence on performance and availability at the earliest possible opportunity.
- How is the connection to the virtual power plant of BayWa r.e. made?
The BESS is connected via a control box provided by BayWa r.e. The interface for the connection is a Modbus RTU or Profibus DP. The control box is connected to the battery control unit or overall park management control system.
- How does the management and trading of the BESS and the generating plant work for innovative systems?
The photovoltaic system is connected separately via the solar power trading interface and must be implemented by the operator. The BESS is connected as described via the BayWa r.e. control box.
- How can we ensure that no electricity can be obtained from the public grid for the BESS, which is marketed as part of the innovation tender?
The ban on network procurement must be ensured by the operator’s park management control system. The restrictions within the scope of the innovation tender are taken into account for an optimised trading process by our experienced trading team.
- Does BayWa r.e. also trade storage that is exclusively used to optimise in-house consumption?
The current trading focus is on in-front-of-the-meter applications, i.e. we only trade systems that serve the stability of the public network.
- How is the use of flexibility markets remunerated?
The following remuneration models can be agreed for trading battery storage:
- A fixed storage premium in EUR/MWh
- Floor price/base price (EUR/MWh) with profit sharing from revenues on the balancing energy and spot market
- Profit sharing from revenues on the balancing energy and spot market
- Are the systems also traded on the balancing energy markets?
After prequalification by the transmission system operators, balancing energy can be traded in all control zones. This allows the BESS to generate both attractive additional revenues and at the same time contribute to network stability.
- What services does BayWa r.e. offer in addition to trading battery storage systems?
BayWa r.e. offers a comprehensive range of services for battery storage systems. These include project development, turnkey construction of BESS and technical operational management.
