What are solar energy cost benchmarks?
These benchmarks help measure progress toward goals for reducing solar electricity costs and guide SETO research and development programs. Read more to find out how these cost benchmarks are modeled and download the data and cost modeling program below.
How much does a solar PPA cost?
Solar PPA prices have fallen even more drastically than wind: between 2006 and 2013, levelized PPA prices for ground-mounted solar photovoltaic arrays larger than 5 MWAC in capacity fell by an average of $20-$30/MWh annually and by $11/MWh from 2015 to 2016 to $35/MWh 3.
Why is cost favorability important for wind and solar PV?
For wind and solar PV, in particular, the cost favorability of the lowest-cost regions compound the underlying variability in regional cost and create a significant differential between the unadjusted costs and the capacity-weighted average national costs as observed from recent market experience.
How much does a solar Rec cost?
Compliance-eligible RECs (excluding solar RECs) have reached $60 per megawatt-hour (MWh) in some states in the last few years. Some states have solar carve-out policies. A solar carve-out policy is a special requirement of an RPS that mandates utilities procure solar RECs (SRECs) generated in the state or pay an alternative compliance fee.
