UCA
Utility Communications Architecture - The Utility Communications Architecture (UCA) is a set of standardized guidelines for use by utilities and equipment manufacturers in developing interoperable information systems used for utility business and operations applications. UCA was developed by the Electric Power Research Institute (EPRI) for the electric utility industry and adapted by GRI for use by gas utilities. This effort culminated in an evaluation of UCA in a gas utility environment at Pacific Gas and Electric Company, San Francisco. Source: SCC-Online.de
UCAIug
UCA International Users Group - The UCA® International Users Group is a not-for-profit corporation consisting of utility user and supplier companies that is dedicated to promoting the integration and interoperability of electric/gas/water utility systems through the use of international standards-based technology. It is a User Group for IEC 61850, the Common Information Model – Generic Interface Definition (CIM/GID as per IEC 61970/61968), advanced metering and demand response via OpenDR. Source: UCAIUG.org
UCLA WIN SmartGrid
University of California Los Angeles Wireless Internet SmartGrid - UCLA WINSmartGridTM Connection is a collaborative research program between Universities, Industry and Government whose objective is to advance novel Wireless / Communications Internet Smart Grid technologies in university labs, perform testing in the labs, transition technologies into the field for scaled testing, and work with partners in industry and government for demonstrations and eventual roll out and deployment.

UID
User ID or User Interface Device or Unique Identification Device
UL
Underwriters Laboratories® - Underwriters Laboratories® is an independent product safety certification organization that has been testing products and writing standards for safety for more than a century. UL evaluates more than 19,000 types of products, components, materials and systems annually with 20 billion UL Marks appearing on 66,000 manufacturers' products each year. UL's worldwide family of companies and network of service providers includes 68 laboratory, testing and certification facilities serving customers in 102 countries. Source: www.ul.com
UML
Unified Modeling Language - The Unified Modeling Language (UML) is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems, as well as for business modeling and other non-software systems. The UML represents a collection of best engineering practices that have proven successful in the modeling of large and complex systems.1 The UML is a very important part of developing object oriented software and the software development process. The UML uses mostly graphical notations to express the design of software projects. Using the UML helps project teams communicate, explore potential designs, and validate the architectural design of the software. Source: www.atlas.kennesaw.edu
UMTS
Universal Mobile Telecommunications System - UMTS (Universal Mobile Telecommunications Service) is a third-generation (3G) broadband, packet-based transmission of text, digitized voice, video, and multimedia at data rates up to 2 megabits per second (Mbps). UMTS offers a consistent set of services to mobile computer and phone users, no matter where they are located in the world. UMTS is based on the Global System for Mobile (GSM) communication standard. It is also endorsed by major standards bodies and manufacturers as the planned standard for mobile users around the world. Once UMTS is fully available, computer and phone users can be constantly attached to the Internet wherever they travel and, as they roam, will have the same set of capabilities. Users will have access through a combination of terrestrial wireless and satellite transmissions. Source: www.searchmobilecomputing.com
UPLC
United Power Line Council - The United Power Line Council is an alliance of utilities and their technology partners working together to drive the development of broadband power line solutions in North America. The UPLC is structured by committees that act on business, regulatory and technical issues. It hosts industry events and coordinates with other industry organizations to promote the worldwide development of broadband power line systems. The UPLC is an independent operating entity under the auspices of the United Telecom Council, which is the international association for the telecom and information technology interests of utilities; and which has advocated policies to encourage the development of broadband power line since 1998.

UPN
Utility Planning Network - UPN operates five membership-based peer groups devoted to networking, educating and advocacy: one for utilities involved with advanced metering and smartgrid; one for large energy users; one for leaders in utility energy efficiency programs; one for leaders in utility renewable energy initiatives; and one for utility professionals involved with CIS/CRM and customer care.

UPS
Uninterruptible Power Supply - A device that provides battery backup when the electrical power fails or drops to an unacceptable voltage level. Small UPS systems provide power for a few minutes; enough to power down the computer in an orderly manner, while larger systems have enough battery for several hours. In mission critical datacenters, UPS systems are used for just a few minutes until electrical generators take over. UPS systems can be set up to alert file servers to shut down in an orderly manner when an outage has occurred, and the batteries are running out. Source: PCMAG
USB
Utilities Standards Board - The Utility Standards Board (USB) is a utility industry leader in developing open standards and promoting data interoperability in support of Smart Grid and Advanced Meter Infrastructure (AMI) programs.The USB is a consortium of six large utilities working collectively and openly to accelerate efforts to standardize Smart Grid system functionality and communications interfaces. These utilities control the research agenda, vote on standards proposals, and govern the USB’s collaboration with vendors, industry groups and other Smart Grid partners.
Formed in 2007, the USB was launched on the belief that system interoperability is essential for their companies-and the industry globally-to achieve the societal and business objectives of Smart Grid and AMI programs. Serving twenty U.S. states and Canadian provinces, the USB members are planning and deploying extensive AMI and Smart Grid systems. Source: USB
USCHPA
United States Clean Heat & Power Association - The U.S. Clean Heat and Power Association (USCHPA) brings together diverse market interests to promote the growth of clean, efficient local energy generation in the United States. It is a private, non-profit 501(c)6 trade association, originally formed in 1999 to promote the merits of combined heat and power (CHP) and to achieve public policy support for CHP. In 2007, the association expanded its focus to include advocacy not only for combined heat and power, but also for recycled energy, bioenergy, and other local generation sources that lead to a demonstrable reduction in global greenhouse gas emissions. USCHPA is working to achieve the goal of a cleaner, more affordable, and more reliable national energy system. The USCHPA documents the benefits of clean heat and power to the public and decision-makers. The assocation sponsors conferences, workshops, and advocacy events for the benefit of its members and prepares reports and releases to educate the public about clean heat and power. We create opportunities for our members to network with each other and key government officials. Source: USCHPA
USEA
United States Energy Association - The United States Energy Association (USEA) is the U.S. Member Committee of the World Energy Council (WEC). USEA is an association of public and private energy-related organizations, corporations, and government agencies. USEA represents the broad interests of the U.S. energy sector by increasing the understanding of energy issues, both domestically and internationally.
USEA coordinates participation of the United States in the WEC by nominating representatives to WEC activities and organizing the U.S. delegation to the triennial WEC Congress, WEC Executive Assembly Meetings, and Regional Energy Forums. USEA members serve on WEC technical and study committees. Source: USEA
USGBC
US Green Building Council - The U.S. Green Building Council (USGBC) is a Washington, D.C.-based 501(c)(3) nonprofit organization committed to a prosperous and sustainable future for our nation through cost-efficient and energy-saving green buildings.
