- 11. 11" ERCOT Reports Sufficient Power Expected For Summer 2014 • ERCOT released its Seasonal Assessment of Resource Adequacy (SARA) on May 1. • ERCOT found that ERCOT does not expect periods of limited capacity. – However, ERCOT notes in the SARA that “If an extreme system peak occurs… [condi)ons] could result in an Energy Emergency Alert (EEA), with corresponding public appeals for conserva)on. Depending on the severity of the situa)on and the amount of genera)on available during periods of highest demand, ERCOT could take other progressive steps necessary to protect overall system.” • According to ERCOT’s meteorologist, most of the state should not expect temperatures hoHer than last summer. – While not as hot as last summer, temperatures are likely to be above the long-‐ term historical average in Texas. – July is expected to be hoHest, especially affec)ng Aus)n, San Antonio and the Valley.
- 12. 12" Longer-‐Term Outlook for ERCOT Shows Genera)on Investment S)ll Needed Source: ERCOT, 2015 Report on the Capacity, Demand and Reserves in the ERCOT Region, May 2014 65000$ 70000$ 75000$ 80000$ 85000$ 2015% 2016% 2017% 2018% 2019% 2020% 2021% 2022% 2023% 2024% MW% ERCOT%Summer%Resources%and%Firm%Load%Forecast:%2015C2024% Resources% Load%Forecast% Reserve% Margin%14.3%% 14.1%% 13.8%% 12.3%% 9.8%% 8.4%% 3.5%% 6.1%% 7.4%% 4.8%%
- 13. 13" Opera)ng Reserve Demand Curve To Enhance Efficiency in Scarcity Pricing A Cri)cal Step to Any Future Market Design • The objec)ve of an ORDC (opera)ng reserve demand curve) is to improve the efficiency and accuracy of energy and reserves pricing as opera)ng reserves (that are immediately available to ERCOT to manage the grid in real-‐)me) are depleted and the risk of involuntary load curtailment increases. • ORDC accomplishes its objec)ve by administra)vely adjus)ng prices for energy and reserves to approximate the real cost of customers losing power.
- 14. 14" Drought Update and Available Water Resources For Power Plants • Most electric generators require the use of water for system cooling. • The vast majority of this water is returned to its source – typically a reservoir built by the power plant owner. • Drought condi)ons remain in much of Texas, but the electricity system has remained reliable. Source: United States Drought Monitor – April 29, 2014
- 15. 15" Water Usage In the Average Household • To put water use for electricity into perspec)ve, only about 3 percent of water use in the average household is for electric produc)on. Source: “Viability and Impacts of Implementing Various Power Plant Cooling Technologies in Texas,” Electric Power Research Institute, 2012
- 16. 16" Electric Generators Prepared for Summer Heat • Electric generators prepare facili)es for opera)ons during the summer through rou)ne maintenance, which typically occurs during March and April. – Maintenance includes assessment of physical components of the power plant to ensure con)nued opera)on whenever possible. – Given Texas’ hot climate, power plants are designed specifically for opera)on during the summer. • Summer readiness programs are focused on safety, evalua)on of problem areas, tes)ng, training and communica)ons. – The immediate goal is reliable opera)on of power plants, including “peaker” plants used during )mes of peak demand, such as the anernoon of a hot summer day. – Procedures are also in place to ensure the grid operator – such as ERCOT – is no)fied of offline power plants, to allow for procurement of needed genera)on.

- 18. 18" “Quiet” Hurricane Season Predicted • Hurricane season runs June 1 through the end of November. • Researchers at Colorado State University predict a “quiet” 2014 hurricane season, although the official forecast for the season from the Na)onal Oceanic and Atmospheric Administra)on (NOAA) will not be available un)l closer to June. • El Niño condi)ons over the Pacific Ocean and cooler water temperatures in the Atlan)c Ocean are two factors that are expected to result in fewer storms than normal. 2013 Tropical Storm AcOvity • Electric service providers monitor weather threats around the clock and remain in a state of readiness.
- 19. 19" U)li)es Prepared for Storm Response • Each u)lity maintains emergency preparedness plans to mi)gate impacts from the most common inclement weather, while maintaining crisis response teams to quickly respond to these emergencies and, if necessary, emergencies in other parts of the state or country. • U)li)es perform reviews aner actual ac)va)ons of their emergency plans and make revisions based on lessons learned in order to beHer prepare for future emergency events. • In addi)on to linemen and local contractors, an emergency plan typically includes virtually every company employee -‐ even those who do not tradi)onally work in the field. • Through electric u)lity mutual assistance programs, most u)li)es have access to thousands of linemen and tree trimmers from around the country. • The )meline for restora)on is heavily dependent on the severity of the weather event and the extent of the areas affected. An extremely severe storm can result in outages las)ng a number of weeks. • U)li)es are preparing for outages before they happen by inves)ng in technology to more quickly and accurately pinpoint problems.
- 21. 21" Con)nued Transmission and Distribu)on Investment Needed Throughout Texas • According to the Texas State Data Center, 10 million new residents are expected in Texas by 2040. • From October 2012 to September 2013, u)li)es completed $4.0 billion in transmission projects, including $3.04 billion related to the CREZ project. • The total includes the addi)on or upgrade of 4,156 miles of transmission circuits, among other projects. • Though not shown here, areas of Texas located outside the ERCOT grid are also growing, both in terms of popula)on and economic development. Source: ERCOT, “Report on Exis+ng and Poten+al Electric System Constraints and Needs,” January 2012 (map) and December 2013 (text)
- 22. 22" Distribu)on Investment Also Needed • The need to replace an aging distribu)on infrastructure to meet popula)on and demand growth will require con)nued investment. • It is becoming more evident that rising construc)on material costs are an increasingly important driver contribu)ng to the higher actual and planned u)lity industry infrastructure investments. • Na)onwide, distribu)on investment is expected to be almost triple the size of projected transmission spending, according to the Edison Electric Ins)tute. Distribu)on investment is likely to exceed genera)on and environmental capital spending, as well.
- 24. 24" Remember – no two storms are alike • Specific damage to electric system will be different. • It is not possible to forecast in advance what the exact damage to the electric system will be, so… • It is not possible to give precise outage duraOon esOmates for individual locaOons in advance.
- 25. 25" • Goal – restore power to the largest number of people in the shortest amount of )me quickly and efficiently • Approach: • All electric distribu)on facili)es that did not sustain damage are energized • Simultaneously assess damage • Damaged electric lines are repaired beginning at the substa)on and then proceeding outward toward the ends of the lines • Individual services lines that are damaged receive a lower priority for restora)on un)l the major parts of the distribu)on system are repaired Systema)c Power Restora)on
- 26. 26" Mutual Assistance • Mutual Assistance is a na)on-‐wide program of electric u)li)es willing to safely support other electric u)li)es during major events on a not for profit basis. • Groups of U)li)es have organized by Regions and have formed Regional Mutual Assistance Groups. • They voluntarily help each other restore electric service aner major events, such as ice storms, hurricanes, tornadoes, or floods. • They provide a rapid, scalable and effec)ve response of labor and equipment.
- 27. 27" Hurricane Ike Mutual Assistance
- 28. 28" • 8,500 out of more than 1 million wood distribu)on poles • 300,000 n. of wire & cable out of approximately 140 million n. • 4,000 transformers out of 400,000 • 860,000 meals Hurricane Ike Logis)cs Resources • More than 1 million gallons of fuel for 7,000 vehicles • 2 million lbs. of ice • 94,000 hotel room nights • 5,000 + cots system-‐wide • More than 11,000 mutual assistance crews from 35 states and Canada
- 29. 29" Pre-‐storm: Electric service )ps • Unplug sensi)ve electrical appliances, such as computers and TVs. • If you expect flooding, turn off electricity at the circuit breaker. • If someone depends on electricity for life-‐sustaining equipment, you need to make alternaOve arrangements for them in advance. MAIN
- 30. 30" Post-‐storm: Electric safety )ps • DO call your uOlity to report a downed power line or other electric emergencies • Always stay away from power lines! • Stay away from standing water; energized power lines could be submerged. • Treat all downed lines as if they are energized.
- 31. 31" Electric Weatherhead • Check your home’s weatherhead. • Any weatherhead problems will need to be repaired by an electrician prior to service being restored.
- 32. 32" In Summary • U)li)es plan year round for hurricanes. • Hurricanes present logis)cal challenges for the u)lity. • U)lity workers and mutual assistance crews work well together to restore service safely and efficiently. • U)lity customers should prepare for outages las)ng 2 to 4 weeks, or more, depending on the severity of the storm.
