2、h 17th Street, Suite 900 Rosslyn, VA 22209 March 2016 2016 National Electrical Manufacturers Association ii Executive Summary The National Electrical Manufacturers Association (NEMA) represents electrical equipment and medical imaging manufacturers and is headquartered in Rosslyn, Virginia. Nearly 4
3、00 Members strong, its companies manufacture a diverse set of products including power transmission and distribution equipment, lighting systems, factory automation and control systems, and medical diagnostic imaging systems. Total U.S. shipments for electro-industry products exceed $100 billion ann
4、ually. NEMA funded a Strategic Initiative related to the relationship of electricity and water in urban water systems. It sought to: quantify the effectiveness and electrical efficiency of equipment in facilities representative of the U.S. urban water supplys delivery and treatment systems analyze t
5、he market potential to improve performance by using NEMA Member products. reevaluate the viability of applying energy savings performance contract (ESPC) practices to finance modernization upgrades This report presents the analysis and conclusions. Notable Findings of the Study During interviews wit
6、h NEMA Members, the study team learned that product manufacturers have little to no interaction with end users; products are bought on spec and installation quality/accuracy varies in the field. Likewise, specifier and end-user knowledge on new products, systems, software, and additional options (e.
7、g., metering) is highly variable. Survey and analytical outreach revealed that end users want training and education, for reasons such as aging/new workforce and desire to gain knowledge about the full range of potential new solutions. The survey taught us that most utilities have convoluted design/
8、permitting/ purchasing/installation practices and policies, making “selling modernization” to them difficult. While data about energy savings potential from modern equipment is very interesting, having more NEMA productrelated energy savings data may not impact utility purchasing. Future NEMA/Member
9、 resource allocations should be optimized in training and education of utilities and their associations. 2016 National Electrical Manufacturers Association iii 2015 Studys Summary1 Conclusions/Recommendations NEMA should: Develop programs and tools to assist agency and facility staff, because water
10、agencies lack the analytic capacity and/or staff resources to perform certain energy-related evaluations. Establish a water sector-focus group of water-related associations, facility officials and managers/operators to assist in targeting the most important water-related topics and infrastructure ne
11、eds. Get more involved and maintain a consistent presence in water-related associations, non-governmental organizations, and advocacy groups to increase awareness of NEMA member products, solutions, and services. Facilitate the identification and organization of innovative funding approaches into mo
12、re holistic portfolios for agencies that leverage energy services companies (ESCOs), public and private dollars, and energy utility incentives. Continue to fund, independently or in collaboration with other water-related organizations, the demonstration of technologies, best practices, and other typ
13、es of energy-savings strategies, disseminating the results at water conferences, industry publications, and webinars. 1 Detailed conclusions and recommendations are in the full written report 2016 National Electrical Manufacturers Association iv Abstract Urban water systems throughout the country re
14、ly on energy-consuming technologies to develop, transport, treat, and deliver billions of gallons of water to end users. Over the years, the energy efficiency and performance of these technologies has improved significantly, potentially reducing costs, improving reliability, and providing operationa
15、l flexibility for system managers. Despite these potential benefits, the water sector has been slow to adopt these new and innovative devices. In response, the National Electrical Manufacturers Association (NEMA) selected GEI Consultants, Inc. (GEI) and its partners (the Alliance for Water Efficienc
16、y and M.Cubed) to assess and identify new strategies and approaches to support the advancement of energy efficiency in urban water supply systems. The study team accomplished this by analyzing available information regarding the application of energy-efficient technologies in water systems and the f
17、inancing mechanisms used to fund these improvements. The team also engaged industry and water agency representatives through interviews and surveys to obtain more agency-specific information. Responses and available literature were analyzed to determine the extent of the current market penetration a
18、nd the potential for further adoption. GEIs team also evaluated the viability of energy savings performance contract (ESPC) practices, government grants, and other financing mechanisms to finance modernization and system upgrades. The literature review resulted in the compilation of a significant am
19、ount of information and data produced from numerous studies and projects over more than 20 years of efforts. The studies identified how systems operate, where energy is used most, and where opportunity exists to apply the best management strategies to improve the energy performance of these systems.
20、 The survey was distributed to more than 3,000 water agency representatives nationwide. These respondents represented a regionally diverse set of water agencies and provided meaningful insights into the level of interest in energy efficiency, institutional and financial challenges to advancing effic
21、iency in these water systems, and possible steps that can be taken to overcome them. The study team determined that significant energy-efficiency savings potential exists within the urban water systems and that ESPCs are a viable business model to secure available funds to implement improvement proj
22、ects. Results from this study will inform future collaborations between NEMA members and water utilities as well as the development of plans with measurable outcomes that advance the energy efficiency of urban water supply systems. 2016 National Electrical Manufacturers Association v Table of Conten
