Net Metering and
Interconnection Definitions
These definitions were taken from "Rulemaking on Cogeneration
and Small Power Production," Federal Energy Regulatory
Commission, May 1981, page 2.
- Qualifying facility: In general, a qualifying facility
can only use biomass, waste, renewable resources (including
hydro from existing dams) or a combination thereof as a
primary energy source.
- Qualifying small power production facility: A power
production facility that is also a qualifying facility.
Together with other facilities at the same site, it cannot
have a capacity greater than 80 megawatts.
- Cogeneration facility: A facility that produces
both electricity and steam or some other useful form of
energy such as heat. The FERC rule has no size limit for
qualifying cogeneration facilities. Any cogeneration facility
is a qualifying cogeneration facility.
