Since electrical energy is a form of energy that cannot be effectively stored in bulk, it must be generated, distributed, and consumed immediately. When the load on a system approaches the maximum generating capacity, network operators must either find additional supplies of energy or find ways to curtail the load, hence load management.
Load balancing, load matching, or daily peak demand reserve refers to the use of various techniques by electrical power stations to store excess electrical power during low demand periods for release as demand rises. [1] The aim is for the power supply system to have a load factor of 1.
A balancing authority (BA) is an entity in the US electric system (as well as in parts of Canada and Mexico) that is responsible for grid balancing: resource planning and unit commitment ahead of time, maintenance of the load-interchange-generation balance within a balancing authority area (also known as a control area) and support for real-time load-frequency control.

The need for ancillary services increases with higher renewable penetration, and the supply can be co-optimized with energy and balancing requirements and provided by balancing technologies. Establish bankable revenue models for low-running-hour balancing power plants, including mechanisms like flexibility-linked capacity payments and scarcity ...
Energy from wind, sunlight or other renewable energy is converted to potential energy for storage in devices such as electric batteries or higher-elevation water reservoirs. The stored potential energy is later converted to electricity that is added to the power grid, even when the original energy source is not available.
Short-Term Operating Reserve is a contracted Balancing Service, whereby the service provider delivers a contracted level of power when instructed by National Grid, within pre-agreed parameters. The main, minimum capability requirements for the service are as follows: Minimum Contracted MW capability = 3MW.
Balancing is the methodical regulation of system fluid flows (air or water) through the use of acceptable procedures to achieve the desired or specified design airflow or water flow. When beginning the balance of a system, you must locate the terminal with the least amount of flow in regards to the engineer's drawing.
A similar term to balance of system is “balance of plant (BOP)” which is generally used in the context of power engineering and applies to all the supporting components and systems of the power plant which are needed to produce the energy. These may include suitable transformers, inverters, cabling, switching and control equipment ...
