This book was released on 1992 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is generally acknowledged that improvements to end-use load shape and peak demand forecasts for electricity are limited primarily by the absence of reliable end-use data. In this report we analyze recent end-use metered data collected by the Pacific Gas and Electric Company from more than 700 residential customers to develop new inputs for the load shape and peak demand electricity forecasting models used by the Pacific Gas and Electric Company and the California Energy Commission. Hourly load shapes are normalized to facilitate separate accounting (by the models) of annual energy use and the distribution of that energy use over the hours of the day. Cooling electricity consumption by central air-conditioning is represented analytically as a function of climate. Limited analysis of annual energy use, including unit energy consumption (UEC), and of the allocation of energy use to seasons and system peak days, is also presented.

This book was released on 1993 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes findings from a unique project to improve the end-use electricity load shape and peak demand forecasts made by the Pacific Gas and Electric Company (PG & E) and the California Energy Commission (CEC). First, the direct incorporation of end-use metered data into electricity demand forecasting models is a new approach that has only been made possible by recent end-use metering projects. Second, and perhaps more importantly, the joint-sponsorship of this analysis has led to the development of consistent sets of forecasting model inputs. That is, the ability to use a common data base and similar data treatment conventions for some of the forecasting inputs frees forecasters to concentrate on those differences (between their competing forecasts) that stem from real differences of opinion, rather than differences that can be readily resolved with better data. The focus of the analysis is residential space cooling, which represents a large and growing demand in the PG & E service territory. Using five years of end-use metered, central air conditioner data collected by PG & E from over 300 residences, we developed consistent sets of new inputs for both PG & E's and CEC's end-use load shape forecasting models. We compared the performance of the new inputs both to the inputs previously used by PG & E and CEC, and to a second set of new inputs developed to take advantage of a recently added modeling option to the forecasting model. The testing criteria included ability to forecast total daily energy use, daily peak demand, and demand at 4 P.M. (the most frequent hour of PG & E's system peak demand). We also tested the new inputs with the weather data used by PG & E and CEC in preparing their forecasts.

Download or read book Residential Sector End-use Forecasting with EPRI-Reeps 2.1 written by and published by . This book was released on 1995 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes current and projected future energy use by end-use and fuel for the U.S. residential sector, and assesses which end-uses are growing most rapidly over time. The inputs to this forecast are based on a multi-year data compilation effort funded by the U.S. Department of Energy. We use the Electric Power Research Institute's (EPRI's) REEPS model, as reconfigured to reflect the latest end-use technology data. Residential primary energy use is expected to grow 0.3% per year between 1995 and 2010, while electricity demand is projected to grow at about 0.7% per year over this period. The number of households is expected to grow at about 0.8% per year, which implies that the overall primary energy intensity per household of the residential sector is declining, and the electricity intensity per household is remaining roughly constant over the forecast period. These relatively low growth rates are dependent on the assumed growth rate for miscellaneous electricity, which is the single largest contributor to demand growth in many recent forecasts.
Book Synopsis Targeted Efficiency by : Samuel Dalton Borgeson
Download or read book Targeted Efficiency written by Samuel Dalton Borgeson and published by . This book was released on 2013 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy efficiency (EE) and demand response (DR) programs are designed to reduce energy consumption, mitigate grid capacity constraints, support intermittent renewable energy integration, and reduce pollution for less than the cost of additional generation. However, the savings and flexibility achieved by EE and DR programs are contingent on programs finding and enrolling customers well matched to program objectives. Many EE programs currently rely on broad but shallow savings from prescriptive measures, but growing interest in deeper and more reliable savings is leading to increased attention for program planning and targeting using empirical criteria. Through data gathered by smart meters and software designed to manage and analyze large data sets, the tools required to cost effectively characterize, target, and change patterns of energy demand are beginning to emerge. This dissertation consists of three chapters on the analysis of meter data and one on the policy implications of these new capabilities. Chapter 2 analyzes hourly electricity and daily natural gas smart meter readings from 30,000 residential customers of Pacific Gas and Electric (PG & E). Meter data is used to derive distributions of previously unobserved characteristics of the housing stock. We show that the targeting of EE and DR programs would be improved through selection of households based on their positions within these distributions. It follows that every utility (or public utility commission) with sufficient metering infrastructure could apply similar techniques to improve the targeting, implementation, and evaluation of their energy efficiency and demand response programs. Chapter 3 uses regression models of patterns in daily household electricity consumption to estimate the physical and operational characteristics of homes. We apply semi-physical regressors designed to capture patterns in the space-heating and cooling, scheduling, and occupancy of homes. When applied to data from approximately 160,000 PG & E customers, this approach supports an evaluation of competing regression model formulations and provides distributions of model coefficients used to evaluate patterns of domestic energy use, including annual and system peak coincident air conditioning loads, cooling set points, day of week scheduling, and lighting energy. Chapter 4 presents a method for estimating the hourly timing of occupant driven loads based on smart meter data. The residuals of a predictive regression model are assumed to include occupant activities because occupant controlled energy use is not fully determined by externally observable factors. Occupant activity timing is converted into empirical distributions of the probability of such events by hour-of-day or day-of-week. With estimates calculated for approximately 25,000 PG & E customers and grouped using K-means clustering, prevailing patterns are interpreted as the result of occupant lifestyles -- with applications in efficiency and demand response program targeting. Drawing upon the applications developed in the preceding chapters, Chapter 5 discusses the potential for using smart meter data to support public interest utility programs in the context of ongoing concerns over public disclosure and privacy concerns, including malicious use by bad actors and inappropriate commercial use. We propose differentiated levels of access to meter data, with access to data mediated by delegated analysis, which allows stakeholders to receive the outputs of approved algorithms without requiring direct access to sensitive data. Such a system would provide privacy protection and oversight without foreclosing on creative and innovative uses of meter data.

This book was released on 2010-06-10 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: America's economy and lifestyles have been shaped by the low prices and availability of energy. In the last decade, however, the prices of oil, natural gas, and coal have increased dramatically, leaving consumers and the industrial and service sectors looking for ways to reduce energy use. To achieve greater energy efficiency, we need technology, more informed consumers and producers, and investments in more energy-efficient industrial processes, businesses, residences, and transportation. As part of the America's Energy Future project, Real Prospects for Energy Efficiency in the United States examines the potential for reducing energy demand through improving efficiency by using existing technologies, technologies developed but not yet utilized widely, and prospective technologies. The book evaluates technologies based on their estimated times to initial commercial deployment, and provides an analysis of costs, barriers, and research needs. This quantitative characterization of technologies will guide policy makers toward planning the future of energy use in America. This book will also have much to offer to industry leaders, investors, environmentalists, and others looking for a practical diagnosis of energy efficiency possibilities.

This book was released on 1994 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report details the data, assumptions and methodology for end-use forecasting of appliance energy use in the US residential sector. Our analysis uses the modeling framework provided by the Appliance Model in the Residential End-Use Energy Planning System (REEPS), which was developed by the Electric Power Research Institute. In this modeling framework, appliances include essentially all residential end-uses other than space conditioning end-uses. We have defined a distinct appliance model for each end-use based on a common modeling framework provided in the REEPS software. This report details our development of the following appliance models: refrigerator, freezer, dryer, water heater, clothes washer, dishwasher, lighting, cooking and miscellaneous. Taken together, appliances account for approximately 70% of electricity consumption and 30% of natural gas consumption in the US residential sector. Appliances are thus important to those residential sector policies or programs aimed at improving the efficiency of electricity and natural gas consumption. This report is primarily methodological in nature, taking the reader through the entire process of developing the baseline for residential appliance end-uses. Analysis steps documented in this report include: gathering technology and market data for each appliance end-use and specific technologies within those end-uses, developing cost data for the various technologies, and specifying decision models to forecast future purchase decisions by households. Our implementation of the REEPS 2.1 modeling framework draws on the extensive technology, cost and market data assembled by LBL for the purpose of analyzing federal energy conservation standards. The resulting residential appliance forecasting model offers a flexible and accurate tool for analyzing the effect of policies at the national level.
