City of Naperville Overview • 144,000+ residents • Population grew by 86,000 residents in 1980s and 1990s • 39 square miles • Located in DuPage and Will Counties • 4th Largest City in Illinois • Municipal-Owned Utility (MUNI)
MUNI Regulations • Federal and State governments share in the regulation of electricity. • Public Utilities Regulatory Policy Act (PURPA 1978) allowed wholesale markets to be opened to nonutility generators. • FERC implements the Federal Power Act and regulates transmission and wholesale sales in IL. The Energy Policy Act of 1992 allowed FERC to order transmission access for wholesale power. • Transmission access allowed municipal utilities to become independent and build generation. • FERC 888 (1996) allows electric utilities to buy power on the open market. • State regulation of electricity is done by the Illinois Commerce Commission. • However, ICC does not regulate municipal utilities in IL.
History of the MUNI in Naperville • MUNI started in 1899 • Purchased from IOU • Not-for-Profit Entity • Power is purchased wholesale and then distributed • Triple Function Utility • Electricity • Water Service • Wastewater Treatment
Benefits of the MUNI vs. ComEd • Customers are dealing with a smaller organization • Lower electric rates for customers • The MUNI is a non-for-profit entity • Reduced outage times • SAIDI Index (annual) • 1992: 120 minutes • 2010: 18 minutes • Transparency Galvinpower.org
Electric Facts & Figures • 57,000 electric meters • Peak demand of 388 MW • Annual usage of 1,550,000 MWh • Transmission Lines • 138 KV: 19 miles • 34.5 KV: 33 miles • 12.47 KV: 72 miles overhead and 800 miles underground • 9 Metering Points of Entry Naperville Substation
Electric Power Contracts • J Aron & Goldman Sachs • 4-year contract will expire in 2011 • Wholesale, bulk power market • Joining IMEA: IL Municipal Electric Agency • Will become co-owners of generation • Includes a low-pollution coal plant in Southern IL • Should stabilize prices for customers • IMEA tracks where electricity comes from • 15% of power still purchased wholesale each month IMEA Participants
Infrastructure Planning • 1960s: prior to growth, city decided that all future distribution lines should be underground • 1992: decision to invest more to counteract outages and started burying existing lines • 2008: $8M allocated for 5-year plan of improvements • 2009: Received ARRA/DOE grant funding for Smart Grid • $11M Grant • $11M match by City • Only community in IL to receive, 100 communities overall • Project completion in 3 years (instead of 10-15)
Naperville Smart Grid Initiative • 57,000 smart meters will be installed- ALL customers • Residents with renewables with get meters first • Time of use rates being developed, though customers can choose if they prefer to keep existing rate structure • Utility expects a 3:1 ratio between peak and off-peak rates • Secure wireless access to data • Automation of entire system; software • Safeguards against hackers and theft • Project completion by April 2013 Naperville resident with smart meter at her house
Smart Grid Customer Bill of Rights • A proactive measure for customer peace-of-mind • Right to be Informed • Right to Options • Right to Privacy • Right to Data Security
Smart Grid Anticipated Benefits • 5% reduction in total energy usage • totaling 819,000 MWh over the period from 2012-2023 • 6.5% reduction in peak demand • from 400 MWh (projected) to 374 MWh by 2023 • $22.3 million in customer electricity cost savings. • This is in addition to $450 million in savings compared to the projected cost of using Commonwealth Edison to supply Naperville’s electricity over the past 15 years. • 180,000 tons of carbon emission reductions • Increased business opportunities • 139 new jobs related to implementation of the smart grid
More Smart Grid Benefits • Customers will save “significant amount” on monthly bills. • 5-15% projected savings • City expects to save $2-3M per year for the next 10-11 years • Greater efficiency of transmission • Faster outage response time • Smoothed out demand • Ability to absorb more intermittent sources such as wind and solar • Paves the way for Electric Vehicle integration • Streamlined billing

Renewable Policies • Naperville does allow solar panels on roofs. • Wind turbines are being debated. • Naperville Plan Commission is currently working on guidelines for placement, maintenance of equipment and appearance for future solar and wind installations. • Homeowners who are net metering can sell electricity back to the city for same rate the customers purchase energy. • City has installed Solar PV panels at substation.
Green Energy Options • Residents have option to purchase “green power” • According to Dept of Energy, Naperville ranks 5th in the country for participation • 10% participation • $5 per month for 200 kwh • City buys RECs through Community Energy • 70% IL wind • 1% IL solar • 29% hydro
