MG&E: Commercial & Residential Programs on Energy Conservation, Renewables, and Green Buildings Lynn Hobbie, MG&E MGE BUSINESS Energy Efficiency Programs and ServicesMGE delivers gas and electric service to more than 10,000 business locations. This includes small retail shops to major manufactures. Large or small, we work with companies of all sizes to improve their energy efficiency. Last year we helped businesses save 410,000 therms of natural gas, 8,700,000 kWh and 1,190 kW of electricity. For comparison, that’s double the amount of electricity used annually by Monona Terrace Community and Convention Center. There are five core services that help businesses control their energy costs: Energy Efficiency Education, Account Management, Business Efficiency Consultation Services, Business Efficiency Project Financing and Technology Training. Energy Efficiency Education MGE offers businesses tools to control their energy use and identify energy conservation measures that fit their business. We answer thousands of questions annually about saving energy, technology, power quality, alternative energy, and equipment operation. Some of the services we offer include: · Free energy audits help customers recognize their biggest energy end-uses and understand how they are billed for service. We identify conservation opportunities and calculate the energy paybacks for recommended actions. · New construction design assistance including green and sustainable building practices and facility planning. · “MGE Talks Business” newsletters published three times annually; highlights energy conservation projects by local companies. · Fact sheets describe technology applications that can help businesses save energy, such as “super T-8” lamps or adjustable speed drives (also available on our web site). · Major Customer Council meetings keep businesses up-to-date on national and local energy issues, utility infrastructure improvements and energy price forecasts. Facility tours showcase practical applications of new technologies or best practices in facility management. · “Energy Events with MGE,” are customized, energy efficiency workshops by MGE staff that companies can present to their employees. Topics include energy conservation at home and in the workplace, and alternative energy choices, such as solar or wind power. Account Management MGE Account Managers call on approximately 500 businesses annually to discuss energy issues. Experienced account managers offer a single point of contact for energy-related issues and advice. They link businesses to state and national energy resources, conservation incentives, and help customers secure financing for energy efficiency improvements. Account Management services include: · Large customer Account Manger: Each large customer has an assigned Account Manger that they rely on to keep them up to date on energy issues and changes in the gas and electric industry. Their Account Manager is their one stop shop for utility issues. We can help them to improve their energy efficiency, expedite construction projects or answer questions concerning their energy bill. · Small Business Efficiency Initiative. After an energy audit with an MGE account manager, customers receive an energy profile and customized energy recommendations, with follow up contacts. · Presentations to local associations, service clubs, and chambers of commerce. We offer energy conservation advice at trade shows, local chapter meetings, business forums, and community events. · Business interruption planning assistance and electrical outage response. In the event of an electrical service disruption, we maintain around-the-clock communications with major employers, government, schools, hospitals and other vital services. · Outdoor Security Lighting program. We lease energy-efficient outdoor lighting fixtures for parking and building security. Approximately 2,100 fixtures are currently leased. ESS EFFICIENCY CONSULTATION SERVICESMGE BUSINESS EFFICIENCY CONSULTATION SERVICESWhether they are planning a new facility, replacing equipment, or just concerned about better managing energy costs, MGE’s engineering staff can save our business customers money. We can provide analyses of specific equipment or entire facilities. Services may include: · Energy use analysis and benchmarking · Help with specifying energy efficient equipment · Equipment use monitoring · Facility operations recommendations, including maintenance schedules · Reliable savings estimates · Payback calculations · Information about new technologies · Design review and recommendations Our staff is certified in the Leadership in Energy & Environmental Design Green Building Rating System (LEED). LEED is a voluntary, consensus-based national green building rating standard for developing high-performance, sustainable buildings. It provides a complete framework for assessing building performance and meeting sustainability goals. LEED emphasizes state of the art strategies for sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality. LEED recognizes achievements and promotes expertise in green building through a comprehensive system offering project certification, professional accreditation, training and practical resources. We are also partnering with the Energy Center of Wisconsin to deliver E-Benchmark™ locally. This is a nationally recognized tool to deliver best-in-class energy efficiency and indoor environmental quality in high-performance commercial buildings. It contains over 30 criteria defining high performance in building envelope, lighting, HVAC, power systems and controls. It provides building design and construction professionals with quantitative and descriptive specifications for exceeding state and national minimum standards such as ASHRAE/IESNA Standard 90.1-2001. MGE BUSINESS EFFICIENCY PROJECT FINANCING Businesses can turn to MGE for three different financing options. Participants must satisfy a credit review and provide project information. Projects can include equipment replacements, facility improvements or new construction. Shared Savings Financing We provide a financing program to help business customers fund energy-related projects that save energy dollars or otherwise improve the productivity or efficiency of their businesses. Shared Savings pays the up-front project costs. The money saved from these improvements generally offsets the cost of repaying the money provided by MGE. Customers avoid out-of-pocket expenses. After MGE funds are repaid, they receive the entire savings benefit generated by the improvements. Using this financing option can improve cash flow, reduce maintenance costs, increase property value, preserve capital for other projects and save time. Equipment Leasing MGE can tailor an equipment lease to the needs of a customer. Leasing from MGE offers a company some important financial benefits: · Low initial cash outlay · Monthly payments may be tax deductible · Improved cash flow · Flexible terms that can include maintenance costs in the lease · MGE dependability and service · Rapid response to emergency replacement needs Technology Training MGE offers energy conservation training for business customers. We typically host a half dozen events annually in addition to co-sponsoring training events with the Energy Center of Wisconsin. We also train contractors, equipment suppliers & other trade allies so they can promote energy efficient equipment to their customers. Technology training sustains demand for energy-efficient products, moves equipment manufacturers to develop new lines, and insures local distributors offer energy-efficient options. Recent training topics have included: · Motor & pump performance · Air handling unit operation · Building Operator Certification (nationally accredited) · Practical Energy Management · Lighting system design MGE RESIDENTIAL AND MULTIFAMILY ENERGY EFFICEINCY SERVICESCustomers turn to Madison Gas and Electric for energy efficiency information before purchasing appliances/products, when building or remodeling, and during times they to need to address a problem or find ways to lower their energy costs. We are committed to providing advice and materials to meet the energy efficiency needs of our diverse community. Last year residential and multifamily customers saved over 16 million kWh of electricity and 2 million therms of gas through the full range of information services provided by MGE. · MGE Library of Educational Materials A wide range of topics is covered in brochures and fact sheets that provide practical information that encourages homeowners, tenants, and property managers to implement energy saving measures. The topics include purchasing high efficiency appliances and products, do-it-yourself energy improvements, and low and no cost tips to save energy. Materials are available to customers 24 hours per day, 7 days per week through our website at mge.com. According to recent surveys MGE’s website is most visited website by customers who take action to save energy. · Home Energy Line Highly trained residential energy experts staff a dedicated telephone line. They provide individual consultation to customers about improving the efficiency of their homes, energy considerations for new purchases, and addressing specific energy problems. · Information for Spanish speaking customers Full range of written materials is translated into Spanish and distributed through community organizations and to individual customers upon request. Spanish speaking customers call our Spanish line to get the information they need to cut their energy costs, learn about billing options, as well as, sign up for MGE services. In addition to our materials being translated into Spanish, we are currently working to make them cultural sensitive. · Welcome Packets Since most home improvements are implemented within the first two years of owning a home we send energy efficiency and energy saving information to 16,000 to 20,000 new customers each year. · Community Newsletters and Events/Shows We offer articles on seasonal energy efficiency topics for neighborhood and grassroots organization newsletters. We participate in over 50 community shows and events annually and promote energy efficiency brochures and handouts, advise customers face-to-face about energy topics, and highlight energy topics and technologies. · Environmental Action Teams We are a major sponsor of the Environmental Action Teams. Neighbors work together to make lasting behavioral changes to reduce their household impact on the environment. Last year we worked with Madison Environmental Group to provide extra financial support to recruit volunteers for the program, offer incentives to participants, and to promote participation in the program. · Community Energy Projects MGE offers resources and funding for neighborhood association and community center initiatives that educate their communities about energy conservation and result in energy savings. · Library Partnership We contribute energy-related resources to the Dane County Library System for circulation throughout the county. In addition to a wide selection of books, the energy meters we provide are very popular. Customers can check out a meter to find out how much individual appliances in their home cost to operate. A toolbox is also available to provide the tools needed to implement simple energy improvements. Energy displays and workshops are regular features in Dane County libraries. · First Product Loan Owners and managers of multifamily buildings are often reluctant to invest in energy efficiency technologies and products that they are not familiar with. To overcome this obstacle to the implementation of new technologies, MGE provides energy products that are new in the market to owners/managers on a trial basis. If the product works to the owner’s/manager’s satisfaction they reimburse MGE for the product, otherwise MGE takes the product back and finds an application for it in another property. · Green Building Reflecting the interest of our customers MGE has been a long-time supporter of green building. Energy efficiency and green building practices go hand-in-hand to reduce the environmental impacts of our built environment. Working with the Madison Area Builder’s Association, UW-Extension, and Wisconsin Environmental Initiative (WEI) we promote green building practices to local builders and consumers. We display recycled building materials and distribute information at home shows and the Parade of Homes. As one of two Green Built Industry Leaders with WEI our goal is to increase the number of homes and builders in Dane participating in the Green Built Homes program. To develop the next generation of builders as energy-efficient, green builders MGE provides education and funding to the LaFollette High School building trades class to build a certified Green Built Home. A certified LEED Engineer is available at MGE. The LEED Engineer assists customers and Architects in LEED selection (not design). · Wisconsin Energy Star Homes This is a statewide program that MGE helped to develop. As an Energy Star Partner, we promote the program to local builders, remodelers, and homeowners. · New Home Planning Book This well-researched resource developed by MGE provides practical information for consumers and builders that want to build an energy efficient new home. · Community Housing Projects MGE promotes energy-efficiency in affordable housing. We provide design assistance, energy advice, and funding to non-profit organizations constructing homes with 1- 4 units. We conduct training for agency staff and the new residents about conservation practices that will make the homes more affordable to live in. Harbor View Apartments. · Consultation Services MGE energy experts review plans and provide advice to developers, architects, and property owners to promote energy efficiency into new construction and remodeling projects. · Neighborhood Revitalization Projects We provide developers with custom advice on technologies and practices to increase the energy efficiency of large multifamily projects, assist with writing efficient technologies and products into project specifications, and fund energy-efficient products and technologies. The program is designed to encourage energy efficiency in multifamily projects with 50 or more units, with 25% or more of the units dedicated to low-income households, and where the development is located in blighted neighborhoods. MGE staff conducts training for management staff and new residents about conservation practices that will make the homes more affordable to live in. MGE customizes testing on an as needed basis for any customer, not limited to low income. Benchmarking for Energy Star is not available. This is an item that MGE wants to pursue. Geo- thermal has been investigated for small and large projects. Cogen plants are used for large facilities. Equipment leasing is primarily for hot water systems. MGE RENEWABLE ENERGY Our customers are interested in and support renewable energy options. MGE is committed to providing green energy options for our customers. The following projects are offsetting the use of non-renewable sources of electricity and are giving us a better understanding of the available technologies and their viability as reliable energy options. The following table summarizes the renewable electricity generated and sold to MGE customers in 2003.
Solar Electric Systems MGE invests in these systems to: · Evaluate performance of various technologies · Determine economics of photovoltaic systems in our communities · Find cost-effective, clean energy options for customers · Become an objective resource for customers about photovoltaic systems · Help develop the market for photovoltaic systems Much more information about the following installations is available at: http://www.mge.com/environment/solar/index.htm. · Solar in Schools Partnership Students are the energy consumers and producers of the future. They will make the hard decisions about which energy resources to use and develop, with the associated impacts on our local and national economy and environment. We can help our community prepare for the future through this program which is helping to educate our children and raise the visibility of energy issues and renewable technologies within our community. MGE’s Foundation has funded solar photovoltaic (PV) array installations on all ten high schools in our electric service area. We have also installed monitoring equipment to allow students and others to keep track of energy output and weather information on MGE's Web site at: http://www.mge.com/community/schools/PV/index.htm Teachers, school district staff, MGE and the Wisconsin K-12 Energy Education Program (KEEP) staff are creating educational materials and teacher training to make the most out of this learning opportunity. These ten systems combine for a total capacity of 19.2 kW AC and generate 27,600 kWh each year (enough to provide for the annual energy needs of 4 average homes). · Dane County Arena PV Project – This is a 16-panel array manufactured by ASE America. The 4.8 kW AC system generates 5,213 kWh each year (enough to provide 9 months of energy for an average home). · Society of Friends Meeting House PV Project – This project is a building integrated system manufactured by Uni-Solar consisting of 30 metal standing-seam, integrated roof panels. The 3.0-kW AC array generates 3,470 kWh each year (enough to provide 6 months of energy for an average home). · UW-Madison Arboretum McKay Center PV Project – This 860 square foot, 6.4-kW AC Atlantis Sunslate concrete/fiber slate roof building integrated PV system generates 6,000 kWh each year (enough to provide 10 months of energy for an average home). · Lussier Family Heritage Center PV Project – Located at Lake Farm Park, this is a two-panel array with dual-axis tracking, manufactured by Sharp USA. This 1.32-kW DC system generates 2,150 kWh per year. MGE also installed a data monitoring system providing Internet-based live system data and graphs, and historical data. · Dane County Henry Vilas Zoo PV Project – This dual-axis tracking array manufactured by ASE America can be found in the flamingo enclosure. The 1.2-kW DC system generates 1,950 kWh per year. MGE also installed a data monitoring system providing Internet-based live system data and graphs and historical data. This summer we will complete installation of an educational kiosk in the Discovery Center. · City of Madison Solar Parking Canopy Project – This building-integrated PV project, located behind the Madison Municipal Building, is scheduled for completion this spring. The 8-kW DC system manufactured by UniSolar is expected to generate roughly 9,300 kWh per year. It also will include a data monitoring system providing Internet-based live system data and graphs and historical data. · MATC PV Project – MGE operates and maintains two arrays—a fixed mount and a dual-axis tracking array. Combined, the 3.36-kW DC system manufactured by Kyocera generates 4,900 kWh per year. Wind Energy MGE owns and operates an 11.22 MW wind farm in Kewaunee County. This is the largest Wisconsin wind farm owned and operated by a Wisconsin company. Each year MGE’s wind farm produces around 23,000,000 kWh of electricity. This is enough to serve the annual energy needs of 3,300 average residential customers. This investment is roughly three times the statutory requirement for providing renewable energy to our customers. Three-quarters of the energy produced is sold through MGE’s successful green pricing program. Through this program, residential and business customers choose to pay a little more for electricity every month to cover the higher costs to produce clean, renewable wind energy. A greater percent of MGE’s customers are supporting green pricing than those of any other investor-owned utility in the nation. MGE’s investment in renewable energy for our wind power program is the most significant in Wisconsin. It represents the most renewable energy generated per customer; is the “greenest” energy—100% wind power; and has the highest participation rate as a percentage of customers overall. Now, MGE is about to announce our next wind energy project. Working together with Wisconsin Public Power Inc., we are reviewing 16 proposals from wind developers to add significant new wind capacity in Wisconsin. We expect to select winning proposals within the next few weeks and begin producing wind power by 2005. Landfill Gas MGE purchases electricity from the Dane County Rodefeld Landfill where generators run on methane gas. Dane County taps into the methane gas produced naturally in the landfill. The generators export the energy to MGE's distribution system. In 2003, the methane gas produced 12,766,000 kilowatt-hours, enough to power about 1,725 homes annually. Alternative Fuels at Blount Station Using a variety of alternative fuels at Blount Station is not a new concept. MGE has been testing and using various kinds of pre- and post-consumer wastes for electricity production for over 20 years. Blount was one of the first electric generating stations in the country to use its steam boilers to burn alternate fuels such as waste paper and plastic. In 2003, MGE generated 15,688,000 kilowatt-hours using alternative biomass fuels. · Pre-consumer waste – MGE burns a variety of pre-consumer wastes. We focused on clean, separated and non-recyclable waste paper products or other comparable sources. We were interested in helping reduce the quantity of wastes going to landfills and reducing sulfur dioxide air emissions, providing more positive environmental contributions. Madison General Fuels Corp. (MGF) supplies us with these fuels and operates our on-site alternate fuel facility. MGF provided us with various paper and non-PVC poly/fiber products. · Poly-derived fuels (PDF) – These alternate fuels have a high-energy content and cost less than coal. They also produce less ash and lower emissions than coal. The Blount Station continues to burn PDF, and through the Environmental Cooperative Agreement signed September 26, 2002, has gained approval to burn more PDF as long as all air emissions guidelines and regulations are maintained. · Switchgrass – We embraced the opportunity to test burn switchgrass in a pilot project jointly funded by MGE, the Electric Power Research Institute and the Council of Great Lakes Governors in 1995 and 1996. Switchgrass is an easy-to-grow prairie grass that could potentially be produced locally. Conversely, it can be dusty and hard to handle and store—not insurmountable problems if it can be regularly burned, cost-effectively.
MGE has continued interest in pursuing this fuel, currently funding three years of switchgrass research by the University of Wisconsin Center for Sustainability and the Global Environment through the MGE Foundation. MGE works with local companies to develop solar collector projects. The solar collector project at Madison Municipal Building is scheduled to be producing energy on or before April 22, 2004. MGE is currently working on purchasing additional wind farm energy. MGE reports that consumption per customer of natural gas is declining.

Kelley Simonds Energy Efficiency Improvements CDA/Housing Operations, City of Madison High efficiency refrigerators are installed at:
High efficiency refrigerators are scheduled for installation at:
The replacement refrigerators use high efficiency scroll compressors and have added cabinet insulation. The replacements use from 20 to 35% less energy than the units removed. MGE shared savings has financed the program. 7% of the units are in single family. High efficiency boilers (non condensing) have been installed at:
Cast iron, standing pilot, gravity vent, 70% efficient boilers have been replaced with 80%, copper tube heat exchanger, power vented units. The total replaced capacity is 9.75 million BTU’s. Condensing boilers will be used in future replacements. High efficiency furnaces have been installed at:
The replaced units were 75% efficient, gravity vent, standing pilot furnaces. The replacement units are 91%, power vented and use exterior air for combustion. High efficiency furnaces are scheduled for installation at: 1. Parkside Townhouses – 12 units The old units are 75% efficient, gravity vent, standing pilot furnaces. The replacement units will be 92% percent, power vented and will use exterior air for combustion. Required underground piping was installed by MGE. Upgraded thermal envelopes have been installed at:
Primary-Secondary loops w/outside temp reset controllers and WW shutdown added at:
Due to a design oversight, the boilers at these addresses were installed without the proper reset controllers and no primary / secondary loop separation. These are now in place allowing for much lower water temperature in buildings and also allowing boilers to operate at optimum settings. Secondary (building) loops are automatically adjusted to match heat loss of building as outside temperature changes. MGE financed with the shared savings program. Torchiere replacement program, all CDA Housing units: In 1998 CDA/Housing partnered with MG+E to eliminate all 500-watt Halogen torchieres. We offered free replacement for any of the Halogen units brought to our site offices with units using 22-watt fluorescent bulbs. Several hundred units were exchanged. Automatic Primary controls added to Romnes Hot Water system. These allow the system to go offline when the storage tank is satisfied. The past system called for primary circulating pumps to run continuously. This has resulted in the pumps cycling off roughly 18 hours daily, a 75% reduction. Automatic secondary controls added at: 1. Truax Park Apartments 2. Romnes Heat and Hot water 3. Brittingham 4. Parkside These added controls allow us to run equipment only as needed. In severe weather the practice had been to run back-up equipment concurrently with primary equipment to ensure heating in case of a failure. The added controls allow us to keep the secondary equipment on stand-by, reducing electrical load and stand-by losses. Auto-relight modules have been added to water heaters throughout housing properties.
Where we have tandem water heaters that serve multiple apartments, the practice had been to raise the operating temperature of all units to help supply Hot Water in the event that one of the units failed. This not only created excessive stand-by losses but also created a scald hazard. The Auto-relight modules allow us to keep domestic Hot Water temperatures at optimum levels for efficiency and safety. Temperature reset controllers have been repaired on all boilers and thermostatic zone valves have been added to all (approximately 600) radiators at Truax Park Apartments. Non-functional boiler temperature controls have been repaired and zone valves have been added. This has allowed reduced operating costs and significantly increased tenant comfort. Partnering with Project Home: All housing units. We have recently begun to work with Project Home on weatherization of our buildings. We expect to reap significant gains in tenant comfort while reducing utility usage. Fresh air intake furnace: Brittingham We have contracted with Affiliated Engineering to design a fresh air intake system, which will use the hot water from our high efficiency, hydronic boilers. This will reduce utility costs compared the current 500,000 BTU rooftop furnace unit. Additional Comments:
