In a wide area synchronous grid the short-term balancing is coupled with frequency control: as long as the balance is maintained, the frequency stays constant [4] (at the scheduled frequency), whenever a small mismatch between aggregate demand and aggregate supply occurs, it is restored due to both supply and demand being frequency-sensitive ...
The energy transfer on Pole 1 was strictly limited to the northbound direction, to reduce the stress and strain on the aging converter system. In May 2009, Transpower placed the remaining capacity of Pole 1 back into service for a short period, at a limited capacity of 200 MW, in response to a temporary loss of capacity on Pole 2.
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.
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.

Vehicle-to-grid is a system under development allowing electric cars to provide power to the grid at times of high demand, low supply from e.g. wind and solar power and therefore high prices, and charge the car again when the price is lower, based on the energy need the car owner has defined in the car settings (such as need for long distance ...
According to the New York Times, here's exactly how to play Strands: Find theme words to fill the board. Theme words stay highlighted in blue when found.
Utilities, meanwhile, are the best defensive sector amid strong energy demand from AI and electric vehicles, the analysts said. Utilities have outperformed in recent months, with the MSCI ACWI ...
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 ...
