GTM Research Solar Analyst Cory Honeyman spoke this week at Solar Power International's Industry Trends booth where he honed in on five U.S. states with big upside in solar growth.

Growth in U.S. solar has been remarkable. As we've reported, 8.9 gigawatts of solar has been installed through the first half of 2013 and the 10-gigawatt threshold was crossed recently. What's more, three-quarters of U.S. solar installations have happened in the last 2.5 years.

Up until now, this demand had been clustered in 6 established state markets (California, New Jersey, Arizona, North Carolina, Massachussetts, and Hawaii). California alone deployed 846 megawatts in the first half of 2013

 

But this clustered growth is subject to change. Here are five states staged for growth through a combination of favorable market fundamentals, regulatory regimes and state incentives.

 

Georgia

Demand for solar in Georgia will be driven by an attractive feed-in-tariff and utility-scale RFPs for 20-year PPAs. The Georgia Advanced Solar Initiaitive offers 13 cents per kilowatt-hour for distributed generation and 12 cents per kilowatt-hour for utility-scale. Items that cloud the solar value proposition in Georgia are uncertain rate cases and potential fixed charges. Note that third-party ownership is illegal in Georgia.

 

Minnesota

Minnesota currently has only 12 to 14 megawatts of solar installed but that could change in the coming years. Despite low solar insolation and low retail rates -- the biggest driver will be the 1.5 percent solar carve-out. That should equate to 450 megawatt of demand along with a 10 percent small-scale DG carveout. The state has NEM certainty through 2017 and a VOST mthodology under review. Rate design will be finalized in early 2014.
 

 

Washington, DC

Although Washington, DC has limited rooftop potential, its 2.5 percent solar carve-out by 2023 along with an undersupplied SREC market make for a strong regulatory lanscape. One of the hidden growth opportunities in DC is the the community energy renewables law which leagalizes net-metering for "solar gardens" up to 5 megawatts. Owners of the shared solar installations retain the right to SRECS. The 2.5 percent solar carve-out equtes to about 250 megawatts of demand through 2023.

 

Louisiana

Honeymon called Louisiana "almost unexplored" with its current 10 megawatts. The state has above-average insolation but weak market fundamentals with no RPS or PUC mandates. The NEM is due to remain in its current format. Act 428 revises the state tax credit for TPO systems but guarantees the credit's existence through 2017.

Virginia

Virginia's Dominion Energy has a 50-megawatt pilot PPA program legislated by HB 2334 which trumps low retail rates, low insolation, and weak market fundamentals.The lawand pilot focus on TPO for medium- and large-scale commercial installations.
 

 

Honeymon concluded that Georgia might had most potential demand; the most attractive market might be Washington DC with its aggresive SREC prices; but the "best value proposition" is the Minnesota small-scale DG market with its guaranteed demand and known PBI.

Here's the punchline: There could be more than 1 gigawatt of demand from these 5 states over the next 5 years.
