ONCOR INFRASTRUCTURE DEVELOPMENT Ellen Buck Presentation to Leadership North Texas March 27, 2015
ONCOR: 100 YEARS AND COUNTING Largest Texas regulated utility More than 3,000 employees 10 million living in service area 401 cities and 91 counties Over 119,000 miles of transmission and distribution lines 1
OUR ERCOT REGION 75% of Texas land; 85% of Texas load 38,000 miles of transmission lines 550+ generation units 68,305 MW peak demand (set 8/3/2011) Opened to retail competition in 2002 2
OUR ROLE IN THE MARKET Customer centric Market centric Oncor s role in the Market Provide reliable delivery of electricity on a 24 x 7 basis to our customers Invest in and build infrastructure to support growing economy Provide regulated transmission and distribution service to facilitate operations of the wholesale and retail entities is Regulated by the PUC Ensure that rates charged to the customers: are reasonable and nondiscriminatory, enough to ensure reliable service Ensure reasonable earnings so the regulated utility can: develop and expand in accordance with growth; replace aging infrastructure 3
TEXAS CHALLENGE: POWERING OUR FUTURE GROWTH 4
ONCOR RECENT HIGHLIGHTS CREZ Transmission Helps meet increasing electric demand; reduces costly congestion Links wind & other generation sources; saves 17B gals. of water; reduces emissions by 13% Constructed over 1,000 miles of transmission lines; completed Q4 2013 Advanced Meters Easier outage detection by utility ensures faster restoration Enables customers to better manage energy consumption PUC approved deployment plan in 2008; completed in Q4 2012 Smart Grid Leverage advanced technology to keep pace with 21 st century demands Devices sense trouble & reroute power; maximize utilization of assets Improved demand response, wind integration, line rating capabilities 5
DFW AREA NEW CUSTOMER GROWTH 6
LOAD FORECASTING PROCESS Earlier this month, ERCOT released estimates of summer peak demand at about 69,000 MW, based on 12-year average weather. Currently, ERCOT estimates nearly 77,000 MW of available generation resources for this summer s peak. Data Accumulation Collect seasonal peak load data Data Validation Establish peak for each system component Establish Base for Projections Perform weather corrections (up or down) to design temperature on collected peak load data Establish base for future load additions Incorporate Future Load Additions Non-identified load growth Customer specific load growth Develop Load Forecast Ten year forecast Submitted to ERCOT for long term transmission planning Develop capacity expansion plans as needed 7

PROJECTING LOAD ADDITIONS: ECONOMIC DATA 9
CHALLENGES TO FORECASTING AND PLANNING Where? Location, Location, Location ROW becoming more difficult to obtain What? Solutions for large remote loads are limited or non-standard At what load levels are distribution solutions less practical? Iterative design requests impact resources/lead times When? Lead times can vary greatly for similar load additions due to existing infrastructure Substation or transmission line construction can add to lead time 10
EXAMPLE: URBAN AND INFIELD DEVELOPMENT 3100 Carlisle: Original structures Approximately 25,000 Square Feet and 200 KW New Multi-Family Structure 330,375 Square Feet and 2643 KW 11
EXAMPLE: URBAN AND INFIELD DEVELOPMENT Older structures replaced with much larger and higher density structures, increasing power requirements, resulting in need to expand and add electric substations and power lines New structures designed to maximize utilization of land Space for traditional electric utility equipment seldom available on-site, resulting in costly specialized equipment Cities have relaxed or minimized building set-back requirements, causing conflicts with new buildings and aerial power lines in ROW, resulting in utility line relocations 12
NEXT STEPS: CONTINUING TO LEVERAGE TECHNOLOGY TO MEET THE CHANGING NEEDS OF OUR CUSTOMERS Maximizing resources to deliver higher quality, reliable power in cost-effective ways Enhancing the ability to manage diverse energy resources Meeting electric needs for Texas growing population and industry Enabling new consumer technologies such as plugin electric vehicles Providing consumers better information and more tools to enable them to be smarter about their energy use 13
