Baseload Power
Key takeaways
- Baseload is the minimum level of electricity demand on the grid at any time — the ‘always-on’ floor.
- Baseload generation runs around the clock; historically nuclear, large gas, and some renewables fit this role.
- Baseload prices are usually lower than peakload prices because the demand is more predictable.
What is baseload power?
Baseload power refers to the continuous minimum level of electricity demand that exists at all hours of the day. It also describes the type of generation that runs continuously to meet that demand — historically large nuclear and gas plants, and increasingly low-carbon technologies.
On the trading side, ‘baseload’ contracts cover delivery across every half-hour of a period (a day, month, quarter, year). They contrast with peakload contracts, which cover only the higher-demand hours.
Why it matters for buyers
Most published wholesale price quotes are baseload contracts — the headline number traders refer to.
If your business runs round-the-clock (e.g. a 24/7 manufacturing or data site), baseload pricing maps reasonably well to your load profile.
If your usage is concentrated in business hours, you carry more peakload exposure than the baseload quote suggests.
