Purchase of electricity based on a well-prepared strategy, investments in own energy generation sources, optimization of distribution parameters or implementation of solutions increasing energy efficiency of enterprises are gaining popularity in the face of breaking new records in energy prices. Entrepreneurs are also more and more willing to use the DSR service, under which companies receive remuneration for their readiness to voluntary and temporary power reduction. This is a good solution as for most companies it does not involve any additional investment outlays, and also does not require significant organizational changes.
The essence of the DSR (Demand Side Response) service is the reduction of electricity demand by consumers during peak demand hours, at the request of the transmission system operator, which in Poland is Polskie Sieci Elektroenergetyczne. DSR is one of many remedial measures used by the grid operator to maintain the stability of the National Energy System.
The service can be used by any positively verified entity with the ability to reduce power consumption. In practice, however, aggregators (companies involved in the acquisition of entities that can reduce power consumption) are interested in cooperation with customers with a reduction capacity of at least 0.3MW.
Energy consumers who use the service participate in system tests (this way their real readiness to lower the power in a critical situation is verified). Currently, on average, once a quarter, they receive a call to reduce power for one hour. Information about the planned test is provided electronically (and sometimes by phone) at least 8 hours in advance. Consumers therefore have time to prepare for the power reduction. It happens that not everyone will manage to reduce the declared level, and the possible consequences are agreed individually with aggregators. The undoubted incentive to use the service, however, is that in the case of well-negotiated contracts, these consequences may be minimal (such recipients will not receive remuneration at most or may be removed from the list of service beneficiaries without financial penalties).
