Geothermal Energy: Renewable energy that harnesses the natural heat of the Earth's interior for heating, frost prevention and electricity generation in geothermal power plants.
Hydroelectric power: Energy that harnesses the kinetic force of water in rivers and reservoirs to generate electricity through generators.
Intake: Part of the electrical installation that connects the distribution network of the supplying company with the general box of the supply points.
Indexed Price: Rates where the price of energyvaries according to its cost in the wholesale market.
kWh (Kilowatt-hour): Unit of measurement of the energy consumed by a supply per hour.
Light marketers: Company that buys energyon the wholesale market and delivers it to users, taking advantage of the electricity distribution networks and billing its customers for the supply. Discover the difference between a marketer and a distributor.
Maximeter: Electric meter that calculates the maximum power demanded during a period of time.
National Energy Commission (CNE): Institution in charge of outlining state policy in the field of energy.
Nuclear Energy: Energy produced in nuclear power plants from nuclear or atomic reactions.
Peak Period: Hours when electricity is more expensive in tariffs with hourly discrimination. From June 1, 2021, in the 2.0TD tariff for supplies up to 15kW, the peak period is from Monday to Friday from 10h to 14h and from 18h to 22h.
Pool: wholesale market where energyis bought and sold.
Photovoltaic Self-consumption: Private production of solar energy by means of photovoltaic panels for own consumption.
PVPC Tariff (Voluntary Price for Small Consumers): Tariff regulated by the government for supplies up to 10 kW, managed by reference marketers and necessary to access the Social Bonus.
