In context: how this plant compares

At 26 MW, Maesgwyn is well above the median wind plant in United Kingdom (10 MW). Technically it is described as Onshore. Its current lifecycle status is “Pre Construction” — so it is not yet, or no longer, generating at full output. Wind turbines convert moving air into electricity; output is variable and site-dependent, and modern turbines deliver some of the lowest-cost new generation on many grids.
