February Outages ! 5

February 2:!Controlled Outages Throughout Texas!•  On February 2, a day when each major city in Texas faced morning temperatures below 25 degrees, 82 generation units either went offline or were unable to start.•  At the height of the outages, over 8,000 MW of generation was unavailable.•  ERCOT, the electric grid operator that covers most of the state, and each utility have procedures governing emergencies like this, and as the problem rapidly worsened, Texans faced a series of controlled outages.•  As designed, the controlled outages prevented much more widespread and long-lasting blackouts. 6!

More than 8,000 MW of Generation Dropped Off Overnight! February 2, 2011 7!Source: ERCOT Presentation to Joint Senate Committees, February 15, 2011

Learning from the Power Outages!Severe Weather Was the Cause•  February 2-4 saw the coldest sustained temperatures in Texas in 20 years.•  From mechanical failures to pressure drops in natural gas supply lines to inoperable equipment, each reported cause of a generation outage or reduction in output was related to the severe cold.Different Types of Power Plants Were Affected•  Coal and natural gas power plants were among the units affected.Plants Were Affected Throughout the State•  Power plants were affected throughout the state, and the power supply was constrained to the Rio Grande Valley all the way to El Paso.•  Plants affected were operated by both competitive and regulated owners. 8!

The generation loss was system-wide and covered units of all ages and multiple types of fuel! Generation Range 0 – 99 MW 100 – 199 MW 200 – 399 MW 400 – 799 MW ≥ 800 MW 9!Source: ERCOT Presentation to Joint Senate Committees, February 15, 2011

Learning from the Power Outages!Rolling Outage Protocols Successfully Protected the Grid•  The ERCOT and utility rolling outage protocols are designed to prevent the entire grid from failing. –  ERCOT directs the utility to shed load; the utility then select customer areas (feeders) to perform rolling outages.•  The protocols attempt to minimize the impact on individual consumers while ensuring the electric grid remains stable, resulting in no further harm.There Are Lessons to Be Learned•  Winterization procedures, communications protocol and regulatory oversight of natural gas for power generation have all been discussed at recent hearings. 10!

Prices in the Competitive Electric Market in ERCOT ! 11

Potentially High Winter !Electric Bills!•  Typically, the largest portion of customers’ electric bills are calculated based on the price of electricity and the amount consumed.•  So even though electric prices have declined substantially in recent years, residents may still see increased electric bills due to higher consumption. 12!

Lower Bills Through!Choice and Energy Efﬁciency!•  Customers in the competitive retail electric market can visit www.powertochoose.org to learn more about available options.•  All customers can contact their electric utility to find out what programs are available, or to find a contractor or vendor who participates in the state energy efficiency programs.•  Customers can also call 2-1-1, the Texas Health and Human Service Commissions information and referral network to learn about programs available in the area.•  Additional resources –  Texas Department of Housing and Community Affairs: www.tdhca.state.tx.us/assist_repair.htm –  Texas Is Hot: www.texasishot.org –  U.S. Department of Energy: www.energy.gov/energyefficiency –  Get Energy Active: www.getenergyactive.org 13!

Natural Gas Prices Have Been VolatileSince 2000!•  Through 1999, natural gas prices were relatively stable, but the cost of this key commodity has fluctuated greatly since 2000, with three exceptionally large peaks during the past decade.’•  While prices have fallen over the past 18 months, natural gas prices today are still double the price of gas in 1999.•  Despite this volatility, consumers have offers available in the market lower than before competition began. 14!
