Capacity

The maximum amount of electricity a power plant or grid can produce or carry at a given time.

Demand Response

A system where consumers reduce or shift their energy use during peak times to help balance demand and supply on the grid.

Energy Efficiency

Using less energy to perform the same task, which helps reduce energy consumption and costs

Fossil Fuels

Energy sources like coal, oil, and natural gas that are derived from the remains of ancient plants and animals

Energy Grid

The network of wires, substations, and power plants that delivers electricity from producers to consumers.

Grid Modernisation

Upgrading the electrical grid to improve efficiency, reliability, and integration with renewable energy sources

Load Shedding

A deliberate shutdown of electric power in parts of a grid to prevent the entire system from failing when demand exceeds supply

Peak Load

The highest amount of electricity demand within a specific period, usually when everyone is using power at the same time

Procurement

The process of sourcing and purchasing goods and services needed by a company, including energy and utilities

Renewable Portfolio Standard

Regulations that require a certain percentage of energy sold by utilities to come from renewable sources

Tariff

Smart Metering

A digital device that automatically records and sends your energy usage data to your utility company, helping to track consumption more accurately

Renewable Energy

Power Purchase Agreement (PPA)

A contract between a power provider and a buyer, typically lasting several years, where the buyer agrees to purchase electricity at a fixed price

Off Peak

Times when electricity demand is lower, often leading to cheaper rates for energy use

Kilowatt-Hour (kWh)

A unit of energy representing the amount of electricity used over time. It’s what you see on your electricity bill, showing how much power you’ve used
