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 4 th 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 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 % 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 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

Renewables in Naperville Substation Battery Storage for Solar First house with solar 2 nd house with solar Solar thermal panels on washrooms at Springbrook Prairie Forrest Preserve Solar panels at substation

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 5 th 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
