SOLAR IN THESOUTHEAST2018 Annual ReportSouthern Alliance for Clean EnergyP.O. Box 1842 Knoxville, TN 37901 865.637.6055

INTRODUCTIONSolar in the Southeast illuminates the critical role ofutilities in the growing southeastern solar market.Southeastern states, particularly Alabama, Florida,Georgia, Mississippi, North Carolina, South Carolina,and Tennessee, grant monopoly utilities, rather thana competitive marketplace, the responsibility andcontrol over power supplies. Consequently, thelocation of a home or business is the primarydeterminant not only of which utility will supply theelectricity, but also the amount of solar within thatportfolio.To provide an equitable, unbiased comparison ofvarious-sized utilities throughout the Southeast,SACE has ranked utilities on the basis of watts percustomer (W/C) of solar power sourced to thecustomer. SACE has also calculated and forecasttotal installed capacity of solar power (inmegawatts, MW) particularly for state comparisons.The purpose of this report is to document currentprogress and trends at both utility and state levels,as well as identify policies and practices to drivecontinued solar growth in the Southeast.ABOUT SACEThe Southern Alliance for Clean Energy (SACE) is anonprofit organization that promotes responsible energychoices to ensure clean, safe, and healthy communitiesthroughout the Southeast. As a leading voice for energypolicy in our region, SACE is a regional organizationfocused on transforming the way we produce andconsume energy in the Southeast.Proper citation for this report: “Southern Alliance for Clean Energy (2019).

EXECUTIVE SUMMARYU T ILIT IE S- South Carolina Electric & Gas (SCE&G)emerged as a solar power player in 2018,joining Duke Energy Progress, Duke EnergyCarolinas, and Georgia Power at the top of ourleaderboard. Each of these utilities offers morethan 400 watts of solar per customer (W/C).- Fellow Palmetto State utility, Santee Cooper,resides at the bottom of the board for both2018 and our 2022 forecast.- Florida Power & Light (FPL) announced a boldcommitment in 2019 that will propel it to solarleadership for the next decade.ST A T E S- Florida is beginning to live up to its reputationas the Sunshine State, surpassing Georgia oninstalled capacity (MW) in 2018. By 2022, wealso forecast solar capacity in Florida toexceed that of North Carolina.- Even with major announcements fromFacebook and Google, Tennessee andAlabama exhibit less than half the regionalaverage throughout our forecast period (2022).CO NT INUED GR O WT HSolar growth continues in the Southeast (adding 65% in 2018). The region willsurpass 10,000 MW in 2019. SACE now anticipates 19,000 MW by 2022, up fromour prior projection of 15,000 by 2021.CUR R ENT AND F UT UR E LEADER SDuke Energy Progress, SCE&G, Duke Energy Carolinas and Georgia Power arethe current utility leaders ranked by watts per customer (W/C) offering unbiasedidentification of leaders in the southeast solar market. Walton EMC, FPL andOrlando Utilities Commission (OUC) join four returning "SunRisers" demonstratingleading levels of planned solar growth.CO R PO R AT E LEADER SHIP2018 was a banner year for corporate leadership on solar (nationwide 2.8gigawatts, GW according to Rocky Mountain Institute)1 and the Southeast wasno exception. Facebook drove major solar commitments in Georgia (203 MW),Alabama (227 MW) and Tennessee (150 MW). Google announced projects forTennessee and Alabama (150 MW each) and also joined with Target, Walmart,and Johnson & Johnson, to contract with Georgia Power for 177 MW of solar.“SUNBLO CKER S”Santee Cooper, North Carolina Electric Cooperatives, and Seminole ElectricCooperative are sticking with outdated plans for low levels of solar. Despite beinghome to several of the corporate projects above, TVA falls into this category, aswell. We project that solar W/C for these four utilities will remain below today'sregional average W/C through at least 2022.1.Solar in the Southeast2018 Annual Report4PV Magazine, December 18, 2018Corporate solar procurement knocks it out of the park in 2018

Currently the top three utilities(DEP, SCE&G, DEC) all hail from the Carolinas – NorthCarolina with a renewable energy and energy efficiencyportfolio standard and South Carolina where major solarlegislation is poised to pass for the second time in five years.SCE&G leapt from below the Southeast regional average in2017 to nearly double the regional average in 2018.Georgia Power has continued deployment of its RenewableEnergy Development Initiative (REDI). The Georgia PublicService Commission (PSC) has an opportunity to reinforcethat legacy of leadership with comparable ambition in the2019 Integrated Resource Plan (IRP).A four-year forecast to 2022 showcases three Florida utilitiesmaking great strides. FPL embarks on the boldest 10-yearsolar commitment of any utility in the country; Tampa Electricincreases solar penetration almost six-fold; and the portfolioof Duke Energy Florida (DEF) starts to resemble that of itsCarolina brethren.Some southeastern utilities, however, fail to exhibit significantsolar ambition. Of these largest utility systems (each serving 500,000 customers), the bottom four (Santee Cooper, theNorth Carolina Electric Cooperatives, Seminole Electric, andthe Tennessee Valley Authority, TVA) are each forecast in2022 to remain below the 2018 regional average.6SYSTEMS WITH 500,000CUSTOMERSFORECASTDUKE ENERGY PROGRESSS2,618SC ELECTRIC & GAS1,706TAMPA ELECTRIC934DUKE ENERGY CAROLINAS903GEORGIA POWER809FLORIDA POWER & LIGHT734DUKE ENERGY FLORIDA676SOUTHEAST AVERAGE631ALABAMA POWER335OGLETHORPE POWER286TENNESSEE VALLEY AUTHORITY251SEMINOLE ELECTRIC CO-OP120NC ELECTRIC COOPERATIVES71SANTEE COOPER422022The 13 largest utility systems in the Southeast each serve more than 500k customers.
