How battery storages reduce costs and increase energy independence of companies

In order to choose the operating mode of the battery storage and optimize its use, it is necessary to have experience in optimizing these systems. For example, Conseko doo uses Fronius inverters in smaller commercial systems, to enable precision settings with different charging and discharging options for batteries

Key factors for decision makers, when considering inclusion in the new model of active buyer, are generated savings and additional revenues from the sale of surplus electricity, as well as the period of return on investment in new energy equipment. Active customers have the possibility of simultaneously generating more income with the savings they achieve, when in addition to the solar power plant, they own an electricity storage facility. Instead of just taking power from the grid, active customers can be almost independent for hours. Active customers sell their excess electricity to the aggregator, or an electricity trader. In addition, they can sell energy from battery storage on several markets: for arbitration and for support services. Auxiliary services from which they can additionally generate income can be achieved through capacity reservation, voltage control or frequency control. How much, for example these revenues can amount to, can be calculated for each individual contract and case.

For the realization of a technical solution which enables the battery storage in the company to connect with the electricity market in a technical sense, you can contact Conseko doo Belgrade. In particular, we analyze integration with the day-ahead and intraday markets through daily price differences, i.e. arbitrage, as well as for revenues in the market of auxiliary services.

A large influx of variable renewable energy sources, sun and wind, that have a variable energy production during the day, affects the stability and reliability of the power grid. On-line battery storages are used to balance the system, using the operating frequency of the network, or on the other hand, for revenues from the difference in the price of electricity on the grid during the day. In this regard, electricity storages which meet the standards of connection to the power grid, with their quick response, help stabilize the operation of the electric power system. For this reason, when connecting new solar and wind farms to the transmission and distribution system, battery storages are a mandatory resource for electricity production.

Battery electric energy storage projects (BESS) make the energy network not only more flexible and stable, but make investments in such projects bankable, with an acceptable investment return period, typically between 6 and 8 years.

When designing battery systems, attention is paid to safety of these systems, efficiency of the energy conversion cycle, operating temperature range, number of battery cycles, energy density, recycling possibilities, but also prices.

For large battery systems on the grid, Conseko doo provides consulting services regarding the selection of batteries and system sizing, through designing to commissioning of large battery systems.
