Cost of balance of system will include the cost of the hardware (and software, if applicable), labor, permitting Interconnection and Inspection (PII) fees, and any other fees that may apply. For large commercial solar systems, the cost of BOS may include the cost of land and building, etc. The cost of BOS can be about two thirds of the total cost.
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 ...
For cost-based decisions, the units in the merit order are sorted by the increasing marginal cost. The graph on the right describes an extremely simplified system, with three committed generator units (fully dispatchable, with constant per-MWh cost): [7] unit A can deliver up to 120 MW at the cost of $30 per MWh (from 0 to 120 MW of system power);
As of the beginning of 2020s, the actual balancing service was provided primarily by the conventional power stations: [1] frequently, the only quick-response safety margin is the inertial response provided by the kinetic energy of the physically rotating machinery (synchronous generators and turbines).
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.

Devon Energy (NYSE: DVN) Q3 2024 Earnings Call ... The great work that the team is doing in balancing the near-term performance with the long-term inventory considerations confirms our confidence ...
A clothes dryer using a load control switch to reduce peak demand. In principle, any appliance that operates to a duty cycle (such as industrial or domestic air conditioners, water heaters, heat pumps and refrigeration) could be used to provide a constant and reliable grid balancing service by timing their duty cycles in response to system load.
