Overview of SEARUC Energy Market: Trends in Electricity and Natural Gas Utilization

SEARUC encompasses a diverse region from North Carolina to Florida, including Puerto Rico, focusing on the electricity market, which has a 62% average home-heating fuel share. Natural gas usage for home heating has declined from 2000 to 2010. The region’s electricity generation varies by state with growing gas-fired generation capacity, encouraged by the North Carolina Utilities Commission's new policies and safety mandates. This overview provides insights into energy production metrics and market trends, emphasizing natural gas and electricity's interdependability.

  2. SEARUCOVERVIEW OF THE REGION SEARUC is a large, diverse area -- Runs from NC south to FL; Puerto Rico west to AR & TX Electricity is the main home-heating fuel in SEARUC -- 62% average market share -58% excluding FL & Puerto Rico -- 23% market share in the rest of the US Gas home-heating share fell from 2000 to 2010 Use of gas for electric generation varied by state -- 62% in FL, 2% in KY in 2011 Gas production varied by state -- 6.3 TCF in Texas in 2010, none in 3 states and Puerto Rico

  7. NORTH CAROLINAGAS-ELECTRIC INTERDEPENDABILITY & RELIABILITY Opened a docket in response to the FERC/NERC Southwest Report No NC gas production - no well freeze-off / processing plant issues in-state Limited issues with electric compression -- One LDC electric compressor station serves a power plant -- 16% of Transco’s mainline compression is electric Gas-fired generation capacity is growing from small base NC generators take steps to firm up fuel supply -- NCUC requires some fuel-oil backup at gas-fired generators  -- NC generators are signing up for firm interstate pipeline capacity

  8. NORTH CAROLINAEFFICIENCY EFFORTS NC General Assembly passed a law allowing decoupling - G.S. 62-133.7 “Decouples” margin recovery from average customer usage -- LDC not punished for promoting efficiency & conservation Major LDCs have decoupling mechanisms in rates LDCs have programs to promote efficiency -- weatherization, energy audits -- efficient appliances

  9. NORTH CAROLINAESCALATING CAPITAL EXPENDITURES Major LDC transmission lines needed to serve generating plants New customer additions -- industrial plants are requesting lines -- low gas prices should encourage residential & commercial additions No cast iron or bare steel main left in NC -- a steady, long-term effort Other safety-mandated expenditures (e.g.: remote, automatic valves) -- a bill has been drafted to allow for pass-through of safety CAPEX - has not been introduced - NCUC has allowed special recovery of safety expenses
