How do I estimate the true cost of wind and solar energy?

To estimate the true cost of wind and solar energy when redundancy requirements are included, we must consider the following additional costs: Overbuild of Capacity: Since solar and wind have lower capacity factors, more generation capacity must be installed to match the output of coal or natural gas plants.

How does redundancy affect wind & solar power?

Redundancy Adds Significant Costs: Wind and solar require substantial overbuild, storage, and backup to provide the same reliability as coal or natural gas plants, drastically increasing their effective costs.

How much does wind energy cost?

It finds that those prices range from as low as $71 per MWh for unsubsidized wind in the Midwest to as high as $164 for solar-plus-storage in the mid-Atlantic. This story also appears in Energywire. Reprinted from E&E News with permission from POLITICO, LLC.

How much does offshore wind cost without redundancy?

Onshore Wind LCOE Without Redundancy: $30–$60 per MWh ($0.03–$0.06 per kWh). Overbuild Factor: Wind has a capacity factor of 30–50%, meaning 2–3 times more capacity is needed to match the annual output of a baseload plant. This increases the effective cost to $60–$180 per MWh ($0.06–$0.18 per kWh).

What happens if a national grid does not have an energy storage system?

Without having an energy storage system (ESS), the national grid will rely on conventional power sources in absence of enough renewable generation to meet the system load. These conventional power generation resources also have some fixed operational and variable maintenance costs.

Is LCOE an inadequate tool for measuring renewables and dispatchable technologies?

They argue that LCOE is an inadequate tool for measuring renewables and dispatchable technologies, like nuclear or gas, because it does not account for the systemwide costs of providing backup to wind and solar.
