California Has Excess Power Without Nuclear

No Rolling Blackouts with San Onofre Shut Down California has excess power available without California’s nuclear power plants. This includes power needed for peak load periods in the summer as well as for grid stability. The electricity grid operator, California Independent System Operator (ISO), has plans to avoid rolling blackout during the summer with San Onofre shut down. At the 3/22/2012 ISO Board of Governor’s meeting presentation on Summer 2012 Operations Preparedness, Neil Millar, Executive Director, Infrastructure Development presented this list of various actions that would mitigate the outage risk: Under mild conditions, the reserve margin is 107MW. Conservation and demand response will provide additional margin. Activating Huntington Beach [gas] units 3 & 4 also mitigates the Los Angeles area outage risk that arises under heavy load conditions. Without both SONGS [San Onofre reactor] units, the Los Angeles area is short approximately 240 MW [under heavy load conditions]. Huntington Beach units 3 & 4 add 450 MW, thus mitigating the shortage. These actions mitigate the outage risk. • Return Huntington Beach [gas plants] 3 & 4 to service • Accelerate Barre‐Ellis transmission upgrade • Accelerate completion of Sunrise and related outage planning • Fully fund Flex Alerts and restart CPUC 20/20 program • Fully utilize available demand response (e.g., as SCE air conditioner cycling) • Seek additional military and public agency demand response • Take longer‐term steps to increase available demand response system‐wide Source: http://www.caiso.com/Documents/BriefingSummer2012OperationsPreparedness-Presentation-Mar2012.pdf SanOnofreSafety.org .

Glossary of Energy and Smart Grid Terms ACCESS POINTS (Aps)
Glossary of Energy and Smart Grid Terms ACCESS POINTS (APs) – Specially configured nodes on wireless local area networks (WLANs). Access points act as a central transmitter and receiver of WLAN radio signals. ADVANCED METERING INFRASTRUCTURE (AMI) – Refers to the full measurement and collection system that includes meters at the customer site, communication networks between the customer and a service provider, such as an electric, gas, or water utility, and data reception and management systems that make the information available to the service provider. ANALOG METER – Analog meters also known as electromechanical are the most common, the simple meter spins forward when consuming electricity. If the analog meter is bidirectional it will spin backwards when your solar electric system is pushing extra electricity back into the grid. The number of times the disc spins forward or backwards determines how much electricity you are using or contributing to the electric grid. The utility company must dispatch a meter reader every month to figure out how much energy is consumed. AUTOMATIC METER READING (AMR) –The technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting, and analyzing. AVERAGE COST – The revenue requirement of a utility divided by the utility's sales. Average cost typically includes the costs of existing power plants, transmission, and distribution lines, and other facilities used by a utility to serve its customers. It also included operating and maintenance, tax, and fuel expenses. AVERAGE DEMAND – The energy demand in a given geographical area over a period of time.

Electric Power Market Summary SUMMER 2006
GOV FERC. Electric Power Market Summary SUMMER 2006 FERC.GOV/MARKET OVERSIGH T FEDERAL ENERGY REGULATORY COMMISSION @ NORTHWEST CALIFORNIA SOUTHWEST MIDWEST SPP TEXAS PJM SOUTHEAST NEW YORK NEW ENGLAND eak electrical demands in summer 2006 were much higher in Palmost all regions of the United States than in summer 2005. Every regional transmission operator (RTO), and most other regions, set demand records. The bulk power grid and wholesale power markets performed well under the stress. Ten percent more electricity was produced by natural gas-ﬁred generators in summer 2006 than in summer 2005. Lower-priced gas, newly installed gas-ﬁred generators, and more expensive fuel oil all contributed to this trend. Market Oversight | Reports & Analyses | Electric Power Market Summary 1 ELECTRIC POWER MARKET SUMMARY SUMMER 2006 Despite spells of record-breaking heat, U.S. consumption of electricity in summer 2006 grew only one percent from the previous summer. Milder weather in parts of June and August reduced consumption in most major power-consuming regions except in the West. Unprecedented generation availability and robust demand response1 helped grid operators maintain reliability during peak periods, but in almost every area they still needed emergency actions such as warnings, public conservation, emergency transactions, and curtailment of interruptible loads. Even areas considered vulnerable—southern California, southwest Connecticut, Long Island, and Ontario— had no load shedding2 or serious market problems. Compared to summer 2005, average wholesale prices for electricity declined in the Northeast and Midwest and rose in PJM (Mid Atlantic and portions of the Midwest) and California. Throughout summer 2006 prices were moderated by lower natural gas prices, greater supplies of nuclear and hydropower, and occasional moderate weather.

Evaluating Residential Consumers' Willingness to Pay to Avoid Power
sustainability Communication Evaluating Residential Consumers’ Willingness to Pay to Avoid Power Outages in South Korea Ju-Hee Kim, Kyung-Kyu Lim and Seung-Hoon Yoo * Department of Energy Policy, Graduate School of Energy & Environment, Seoul National University of Science & Technology, 232 Gongreung-Ro, Nowon-Gu, Seoul 01811, Korea; [email protected] (J.-H.K.); [email protected] (K.-K.L.) * Correspondence: [email protected]; Tel.: +82-2-970-6802 Received: 31 December 2018; Accepted: 22 February 2019; Published: 27 February 2019 Abstract: South Korea experienced a nationwide rolling blackout in 2011 due to a rapid increase in the power demand and a lack of power supply facilities. In particular, the residential sector suffered from considerable inconveniences due to power outages, such as the interruption of elevators’ operation and the stopping of all electronic appliances. Since then, ensuring a stable supply of electricity has emerged as an important task. This note aims to analyze residential consumers’ willingness to pay (WTP) to avoid power outages. For this purpose, 1000 households were surveyed, applying the contingent valuation (CV) method during May 2018. The respondents understood the CV question well and gave meaningful answers. The results show that the mean of households’ monthly WTP amounts to KRW 1522 (USD 1.41). This value is statistically signiﬁcant. Converting it into an annual value and then expanding the value to the country indicate that the annual national value amounts to KRW 360.7 billion (USD 335.3 million). Since a substantial amount of investments should be made by power suppliers to prevent power outages in the residential sector, this value may be accepted as the upper limit of the beneﬁts ensuing from those investments.

Demand-Side Integration in a Restructured Electric Power Industry
21, rue d’Artois, F-75008 PARIS C6-105 CIGRE 2008 http : //www.cigre.org Demand-side Integration in a Restructured Electric Power Industry A. S. CHUANG, C. W. GELLINGS Electric Power Research Institute USA SUMMARY Modern electric power systems are becoming over-stressed due to shrinking reserve margins, elevating electricity cost, permitting difficulties, and financial risks of bulk expansion. Demand-side integration (DSI) addresses these problems through programs that encourage the efficient and effective use of electricity in support of power systems and customer needs. A growing international community including CIGRE Working Group C6.9 has adopted DSI to refer to the underlying technical area encompassing all aspects of Demand Side Management (DSM) in today’s restructured electric power industry [1] [2]. Common drivers, challenges, and forms of demand-side integration are shared internationally [1]. However, lack of consistent use of demand-side terminology creates the need for a framework that defines the relationships between traditional and newly developed methods of demand-side integration. The paper identifies concepts and implementation methods of DSM that remain relevant in restructured environments. The authors analyze a broad range of demand-side implementations to develop a conceptual framework encompassing both vertically-integrated and restructured industry environments, including market environments where demand response programs coordinate customer usage with electricity market conditions. A comparison between load shape impact objectives of programs reveals noticeable terminology differences in regions where electricity markets exist. In these regions, the terms Demand Response and Energy Efficiency have increasingly replaced DSM. Terminology shifts and other industry trends validate the need to extend traditional DSM concepts and methods to formulate a generalized framework.
