Reactive power

This phenomenon arises in delivery points operating the appliances with inductive electricity consumption (such as electric motors, transformer welding machines, etc.) which are causing a phase shift between voltage and electric current. Voltage vectors precede electric current vectors, and the magnitude of this shift is expressed by the “power factor”. The power factor expresses the ratio between active and reactive energy measured at the delivery point. In an ideal case, the power factor value is equal to 1. Then only active energy flows and no reactive energy. If the power factor is lower than 1, reactive energy, which does not do work, flows through the customer's delivery point and the distribution system, unnecessarily loading electrical distribution systems. A tariff for non-compliance with the prescribed power factor value can be prevented by installing a compensation device.

Regulated energy consumer

A physical person or legal entity under contract to receive electricity from a supplier and maintaining the legal right to a fixed cost for gas or electricity supply as regulated by the Regulatory Office for Network Industries. This concerns households and small businesses with an annual consumption of up to 30 MWh of electricity or 100 MWh of gas. Also included are communities of apartment owners with private own boiler rooms, social service facilities, rental and social apartments.

Regulation electricity (RE)

Electricity procured in real time by the transmission system operator (TSO) to balance system deviations, ensuring the stability of the transmission system and the quality of electricity. Regulation electricity can be positive or negative. Positive regulation electricity balances positive system deviations (i.e. excess electricity in the power grid) and requires an increase in electricity production from energy sources or a decrease in consumption on the part of customers. Negative regulation electricity compensates for negative deviations in the system (i.e. a lack of electricity in the power grid), and necessitates a reduction by producers or an increase in consumption by consumers.

Regulation potential of the delivery point

This is the potential to manage and adjust the production and consumption of electricity at the delivery point for the provision of non-certified ancillary services to the power grid. The smart battery storage brAIn is then financially rewarded for such services. The greater the fluctuations are in the production and consumption of electricity at the delivery point, the more frequently we can charge and discharge the batteries in the brAIn system - which means financial rewards. In other words, it is best for regulation if the company does not maintain constant electricity consumption throughout the day. Regulation potential also affects the overall return on investment.

Renewable energy

Energy obtained from a sources that are not exhausted through their use. The main sources of renewable energy include water, wind power, solar power, geothermal energy, and biofuels. These sources are sustainable and contribute to reducing greenhouse gas emissions, thereby promoting environmental protection and combating climate change.
