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.

Electric Power Contracts
J Aron & Goldman Sachs4-year contract will expire in 2011Wholesale, bulk power market
Joining IMEA: IL Municipal Electric AgencyWill become co-owners of generation Includes a low-pollution coal plant in Southern ILShould stabilize prices for customers IMEA tracks where electricity comes from15% 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 CityOnly community in IL to receive, 100 communities
overallProject 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

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
