Municipally-Owned Electric/Gas System (Munis)
Owned & operated by local government. May include Water/Sewer/Telecom. Serves 15% of nation’s electric load – fairly dense
population areas. Often regulated by state PUCs (PSCs). Size of Muni’s varies :
{Class AB - Rev $4M+; C >$200K-$4M; D < $200K}.
May offer generation to distribution. May purchase all or portion of power from others.

Cooperative Energy Utilities (Coops) *
* Also referred to as “Rural Electric Cooperatives”.
Member-owned utilities. Generally not-for-profit / no fed taxes / sometimes
not even state regulated (e.g. PSCW). 1935 FDR’s Rural Electrification – now Rural Utilities
Service. Primarily rural customers over a wide area. 841 Distribution and 65 Gen. & Trans. Coops in US Economies of Scale – as buyer or seller of power.

Investor Owned Utilities (IOUs)
Owned by shareholders – operated for profit.
IOUs serve 72% of nation’s electric needs.
Retail services regulated by state PUC’s (PSCs).
Partially vertically integrated OR structurally separated, by state.
Wholesale services regulated at federal level (FERC).
Other federal regulation by: 1. Nuclear Regulatory Commission (nuclear plants), 2. FCC (joint use of poles w/ cable companies and telecoms), & 3. Securities & Exchange Commission (financial).
Industry trends: de-regulation and market-based pricing VS. re-regulation (e.g. California) Smart meters – advantages v. cost to install

IOUs relationship to the MISO Midwest Independent System Operator
We Energies (Generation & Distribution utility)
All Generation is sold to the MISO at the marginal market-clearing price.
All load to serve retail customers is purchased from the MISO at Locational Market Prices or LMPs. *
LMPs = System-wide Generation price + local transmission losses + local transmission congestion costs
Generation-only IOUs buy all load from the MISO.
* Wholesale customers of the utility are also served at MISO-based pricing.
