Negative electricity price

A negative electricity price is a situation in the electricity market where producers pay consumers to take electricity instead of consumers paying for it. This phenomenon occurs when the supply of electricity significantly exceeds demand, resulting in a surplus of energy in the power grid.

Non-certified ancillary service

Non-certified ancillary service is the provision of regulation electricity (positive or negative) happens at the delivery or at the production point (i.e. behind the smart meter) without any contractual commitment to availability. An entity providing ancillary services does not have to meet the technical and business conditions determined by TSO regulations.

Regulation electricity is provided for a financial reward at a time when it is technically possible and financially advantageous. The provision of regulation electricity occurs by charging / discharging batteries and/or reducing / increasing the power output of energy-intensive technologies, also known as Flexibility. Regulation takes place in the direction of counter-deviation and is billed through the electricity supplier.
