2 History & Background

3 History Regulated public utility that purchases, sells and transports natural gas Established in 1938 by Gastonia businessman Charlie Zeigler In 1951, became the first distribution company in North Carolina to tie into the Williams Transcontinental Gas Pipeline as it crossed Gaston County Merger with SCANA Corporation in 2000

4 Service Territory 560,000 customers 851 employees 29 offices 557 miles of transmission pipeline 11,588 miles of distribution pipeline

7 Product Offerings

8 Compressed Natural Gas (CNG) CNG is a readily available alternative to gasoline that s made by compressing natural gas to less than 1% of its volume at standard atmospheric pressure PSNC CNG - 10 CNG fueling stations available to the public across our service territory 4 million gallons sold system wide last year Over 200 company fleet vehicles powered by CNG

9 Liquefied Natural Gas (LNG) Natural gas is condensed to a liquid by cooling it to about -260 F (-162 C) This process reduces its volume by a factor of more than 600 similar to reducing the natural gas filling a beach ball into liquid filling a ping-pong ball

12 T-01 Pipeline Replacement Project Completed Phase 1 replaced a 25-mile-long section of natural gas transmission pipeline that runs through Polk, Henderson, and Buncombe Counties. Replaced a 1950 s vintage 8-inch pipeline with a new 20-inch pipeline. Completed Phase II installed 48 miles of new 24-inch transmission pipeline through Cleveland, Rutherford and Polk counties. Plans are to complete by year-end Phase III involves installing three miles of new 20-inch transmission pipeline from the end of Phase I in Asheville to Duke Energy s Skyland electric generation facility. Completion scheduled for April Construction of new compressor stations in Cleveland and Polk counties in NC is scheduled to take place in 2018.

17 T-030 Pipeline Extension Project As a result of the strong residential, commercial and industrial growth in both Franklin and Wake counties, there is an increasing demand for natural gas. We are extending a transmission pipeline from Franklinton, NC south to Clayton, NC to meet that growing demand. The new transmission pipeline will consist of 37 miles of 20- inch pipeline through Franklin, Johnston, and Wake counties in NC. The new pipeline will terminate at the Clayton supply interchange facility which will also serve as a future supply interchange with the Atlantic Coast Pipeline project.

18 T-030 Route

19 Atlantic Coast Pipeline A 600-mile interstate natural gas transmission pipeline, expected to bring 1.5 billion cubic feet of natural gas per day to North Carolina and Virginia. The pipeline will begin in Harrison County, WV, and extend southeast through Virginia and then run south to its terminus in Robeson County, NC. The pipeline will be 42 inches in diameter through WV and VA and will transition to 36 inches in diameter in NC. Pending regulatory approvals, the projected in-service date is second half of 2019, and PSNC plans to be a customer of the pipeline under a 20-year contract.

22 Inspections and Maintenance We operate every valve on our system annually to ensure that it is ready for operation in case of an emergency We monitor our systems 24x7 with a state of the art SCADA and control room Monitoring system flows and pressures across the transmission and select pressures across distribution system We patrol and monitor our system every day driving parts, walking parts, and even flying sections

23 We induce an electrical voltage on steel pipe to prevent it from corroding This works in tandem with the coating on the steel pipe Natural gas is naturally odorless, colorless, noncorrosive & nontoxic We add an odorant to ensure that leaks can be detected at very small concentrations We get thousands of notifications every day that someone will be digging around our lines Every day we mark our facilities in the field so that excavators can avoid damaging our facilities We conduct a leakage survey of our system each and every year We inspect certain areas more frequently transmission lines, high pressure lines, & business districts Most leaks are repaired when found but we monitor even all leaks until repaired
