Energy Glossary

Energy Terms Glossary

You can read the terms more easily with the glossary we created for the descriptions and use areas of energy terms, as well as the calculation methods.

Transmission

It is the process of transmitting electrical energy through lines with a voltage level above 36 kV.

Transmission Capacity

It is the electrical energy in megawatts (MW) that can be sent/received at any point of the transmission system.

Transmission System Configuration

It is the general term used for the electricity transmission facilities and the grid.

Transmission System Configuration

It covers the calculation rules that contain details such as the meters to be considered to calculate the electrical energy given to or received from the transmission system, position of the meters in terms of giving or receiving energy, and the coefficients of loss to be applied to the meters.

Inverter

Inverter is a device that converts direct current (DC) into alternating current (AC). It is especially used in solar and wind power systems to convert the generated DC power into usable AC power.

Nominal Connection Point

It is the nominal point used to calculate losses in the Procedures and Principles for the Methodology to Calculate Coefficients of Loss, which was drawn up by the Authority and approved by its Board of Directors to come into effect.

Insulation

Insulation refers to the coating applied in settings with specific materials to minimize energy loss. The insulation materials used in buildings save energy and prevent heat loss.

Geothermal Resource

Natural resource where energy is obtained from the heat underground.

Geothermal Energy

Geothermal energy is the thermal energy originating from the depths of the earth’s crust. This energy is utilized for generating power and providing heat, and serves as a sustainable energy source. For more information, please refer to our article “What is Geothermal Energy?”.

Joule

Energy unit representing an object’s kinetic energy.

Capacity Factor

Ratio of the actual production capacity of a power plant.

Carbon Tax

The tax imposed on carbon emissions to reduce carbon emissions.

Final Day-Ahead Production / Consumption Program

It is the production or consumption values, which the balancing party (to which a reconciliation-based giving-receiving unit is attached) expects to realize the next day depending on their liabilities and the result of the day-ahead balancing, and which the said balancing party reports to the system operator at the beginning of the balancing energy market.

Restriction Management

It refers to the methods to eliminate the restrictions that exist or are expected to exist in the transmission system.

Unrestricted Market Clearing Price

It is the hourly electrical energy purchase-sales price determined by matching the purchase-sales proposals offered for all proposal areas in the day-ahead market for a certain hour.
