Electricity – Reliability, Availability & Redundancy

Blog, Energy, Les Routledge

Intermittent sources of power production such as wind, solar, and bio-gas are frequently criticized as being too intermittent and unreliable to be of value to the electrical grid.  The argument is often put forward that every megawatt or wind energy capacity has to be backed up with another megawatt of production capacity somewhere else on the grid so power is available 7-24.

On one level, that criticism ignores that the direct variable operating cost of wind and solar energy is nearly zero unlike thermal energy plants like gas, coal or nuclear which must pay for fuel to produce energy.
