Electricity: a growing expense
Since the end of 2021, many countries have faced an explosion in electricity prices. This is partly the result of ageing nuclear plants and consequently the lack of supply required to meet growing demand. The tariff shields put in place by certain countries are unfortunately not sufficient to limit industry losses and, therefore, other solutions must be considered in order to reduce grid consumptions, thus reducing energy bills.
Energy storage: a solution to minimise costs while maximising revenues
Energy storage is a real advantage to your overall energy bill thanks to the multiple services it offers:
- Peak-shaving of consumption from the grid: depending on your energy supply contract, it may be necessary to limit the power demands made on the network so as not to incur any additional costs. The storage is then used to provide the necessary additional power.
- Time-of-use bill management: with a storage system, you can limit your consumption from the network during peak hours.
- Self-consumption of renewable energies: by coupling a photovoltaic installation, for example, to a storage system, it is possible to store the surplus energy produced locally in order to consume it later, especially during peak hours.
That's not all: the energy stored can also be a source of additional income. Thanks to grid services, often contracted with aggregators(1), the storage system can be made available to the network for a certain time during the year. It can therefore be used for voltage or frequency regulation, for example. The system owner is then paid in exchange for the availability of its system.
(1) The electricity aggregator is an intermediary between producers, electricity consumers and the energy market. Its role is to balance supply and demand on the electricity grid. The aggregator identifies the flexibilities of electricity consumption and manages them by using the assets of various players in return for a financial valuation.

In industry, the storage system installed behind the meter makes it possible to promote many services to grid operators.
The energy storage system discharges the battery to limit power peaks and reduce the cost of your subscription.
In the event of high energy prices, the storage system discharges the battery to remove or reduce the energy drawn from the grid.

The SUNSYS HES L energy storage system
The SUNSYS HES L energy storage system consists of a bidirectional storage converter and batteries. This native outdoor energy storage solution contributes to the flexibility of the electricity grid as well as to the reduction of costs.
Its operation can be managed by the storage system's built-in automation or may be controlled remotely via third-party software interfaced with SUNSYS HES L.
