What You Need To Know About Energy
What do you know about energy?
What are ways that electricity system operators match power needs to generation on a day-to-day basis?
- Turning on or off adjustable, load-following generators
- Turning on or off short-term "peaker" plants
- Initiating demand-response actions, such as adjusting thermostats for customers who have agreed to it.
- Initiating energy storage, such as pumped hydro or battery storage.
