Baseload
The minimum amount of electric power delivered or required over a given period at a constant rate. Historically provided by coal and nuclear plants that run continuously.
Why It Matters
The concept of baseload is evolving as renewables + storage can now provide reliable around-the-clock power. Solar + battery "firms" variable generation into something resembling traditional baseload.

Capacity Factor
The ratio of actual energy produced by a system to its maximum potential output. Solar typically has a 15-25% capacity factor.
Grid Parity
The point at which the cost of solar electricity equals or falls below the cost of grid-purchased electricity, making solar economically competitive without subsidies.
