Term	Description
Capture Price	Capture prices represent the average price per megawatt-hour (MWh) received by a renewable energy producer for electricity sold in the market.
Congestion	A situation where the demand for electricity transmission exceeds the available capacity of the transmission network or distribution network, creating two subsystems with different marginal cost.
Curtailment	The reduction of generation from renewable energy sources due to grid constraints or oversupply.
Curtailment Rate	The percentage of potential energy generation that is not utilized due to grid constraints or oversupply.
Decarbonization	The process of decommissioning of coal power plants.
Dispatch	The process of where a power plant generate in order to meet demand. In Chile this is regulated and coordinate by the CEN.
Fossil Fuel Generation	Electricity generated from fossil fuels such as coal, gas, and oil.
Hydro Generation	Electricity generated from hydropower plants, including dams and run-of-river technologies
Injection	The process of supplying electricity to the power grid.
Marginal Costs	In Chile, the system operates on a marginalist model, where generators are dispatched based on their variable costs. The marginal cost is determined by the variable cost of the most expensive generation unit required to meet the current demand.
Node	Node refers to a specific point within the power grid, typically at a substation, where electricity is injected by generators or withdrawn by consumers.
Outage	A period when a power plant or transmission line is not operational due to failures.
Peak Price	The highest price of electricity observed during a specific period.
Plant Factor	The ratio of the actual output of a power plant over a period of time to its potential output if it had operated at full capacity the entire time.
Reference Node	A designated node used as a reference point for pricing and other calculations in the power grid. In DNV’s case the reference node is Polpaico 220 kV.
Renewable generation	Electricity generated from renewable power plants, including PV solar, Wind, Run-of-River, Dam and BESS.
Renewable Share	The proportion of electricity generated from renewable energy sources in the total energy mix.
Technical Minimum	The lowest level of operation at which a thermal power plant can safely and reliably operate
Transmission Constraints	Limitations in the transmission network that restrict the flow of electricity.
Variable Cost	The variable cost of a generator refers to the costs it makes for electricity generation and includes Fuel Costs, Maintenance Costs and Operational Costs.
