1 ERCOT PUBLIC 2/14/2014 1 2014 LTSA Scenario and Data Assumptions February 14, 2014

2 ERCOT PUBLIC 2/14/2014 2 Outline  Background  Scenario description – “Current Trends”  Capital cost projections  Fuel price projections  Emission price projections  Additional information

3 ERCOT PUBLIC 2/14/2014 3 Background  ERCOT initiated 2014 LTSA with facilitated stakeholder workshops to develop key drivers and scenarios for long-term transmission planning Jan 13 workshop with expert presentations on key industry and economic topics Jan 23 workshop with TSP presentations, identification of key drivers and initial scenarios Jan 24 workshop to develop detailed descriptions for 6 (of 10) of the identified initial scenarios Feb 14 workshop to develop the remaining initial scenarios, possibly consolidate some of them, and discuss input data options  The remainder of these slides presents input data options for the “Current Trends” scenario as a starting point for further stakeholder input and discussion See also Jan 23 handout

4 ERCOT PUBLIC 2/4/2014 4 Economic Growth Migration to TX along I-35 corridor Growth in south Texas Industrial growth in Houston, I-35, Midland/Odessa, Valley ~1.5% load growth – high growth in near term then tapering off in long-term LNG growth based on permits existing – needs review [What should we assume for future oil production rates?] Weather / Water [No drought situation, but water supply continues to be a concern to existing and new generators. No specific increase in electricity consumption due to drought conditions.] Transmission Regulation /Policy Policy set to reduce constraints Increased DC-tie capacity with neighboring region [has not yet been resolved] Higher reliability [standards are set by NERC] to avoid load shedding End-Use Increased need for ancillary services Increase penetration of demand response [need to specify how or why to be consistent with no reserve margin] Increasing distributed generation [Need to specify how much is added and why] Generation Resource Adequacy No reserve margin set for ERCOT Maintain energy-only market Economic retirements continues based on economics Environmental Regulation MATS and 316B are implemented [by 2016] CSAPR Hybrid [need more specificity to translate to costs for existing facilities] Greenhouse gas regulation set with flexibility No other major changes in environmental regulations Story: Same old, same old [The recent population and economic growth in Texas continues in the near future, fueled largely by the continued growth of the oil and gas sector and the relative robust Texas economy compared to the rest of the U.S. World oil prices high enough to keep increasing oil production in the short-term, keeping domestic natural gas prices relatively low. With low gas prices, several LNG export terminals are built between 2014 and 2024. Modest wind growth continues based on economics without production tax credits. Capital costs for solar continues to decline at a slower rate than recent history. No required reserve margin is set for ERCOT and the environmental regulations continues to be moderate, with no explicit federal carbon tax or required national cap and trade, but greenhouse gas emissions become regulated beyond 2016.] Implications for ERCOT: [Continued modest economic and therefore load growth in Texas.] [Growth in oil production and population across the state leads to new transmission needs [Continued] increased renewables leading to reliability (inertia) issues [No major generation retirements triggered by stringent environmental regulations.] Scenario: Current Trends Alternative Generation Solar: 1000 MW / year Wind capacity addition limit: 3,000 MW/yr Capacity factor wind – rely on historical data from ERCOT Capital cost wind ~$2,000/kW Capital cost solar ~4.4% reduction/year Overall renewable growth driven by economic entry No production tax credit beyond 2013 No change to existing investment tax policy Gas/Oil Prices EIA reference case or best available gas and oil price forecasts

19 ERCOT PUBLIC 2/14/2014 19 Additional Information

20 ERCOT PUBLIC 2/14/2014 20 Wind Installations by Year Average installations per year for all years is 801 MWs. Average installations per year for the years 2006 thru 2009 is 1,766 MWs

21 ERCOT PUBLIC 2/14/2014 21 Two DOE commissioned reports released in 2012 addressed LNG exports. Key conclusions: –Increased LNG Exports benefit the US Economy –Global Markets for LNG may limit natural gas demand growth and domestic price increases. –In no cases modeled did the U.S. wellhead price increase by more than $1.09/Mcf due to market-determined levels of exports.

In the Low Cost Renewable case, they decline to 1,500 2012$/kW by 2030.
