MAJOR NSR/PSD PERMITTING:
In attainment areas, 250 tons of any criteria pollutant triggers PSD.
TREATMENT OF EMERGENCY ENGINES:
There is an exemption for emergency units powered by internal combustion engines which are fueled by gaseous fuels, gasoline, or distillate fuel oil
with an electrical output of less than 3,000 kW and are limited to operating 200 hrs/year.
RECENT REGULATIONS:
Wisconsin officials have revised their hazardous air pollutants rule.
The first comprehensive revision to Wisconsin's hazardous air pollution rules added 148 hazardous air pollutants
to those currently listed and revised the emission standards for 116 of the 438 air pollutants already listed. The state
Natural Resources Board at its April 22, 2003 meeting approved revisions to NR 445 of the Wis. Admin. Code, under which
the Department of Natural Resources regulates the emissions of hazardous air pollutants. The revisions represent the first
comprehensive update of the rule since it was adopted in 1988.
The NR 445 section related to control requirements for stationary
compression ignition internal combustion (CI) engines has been revised. Owners or operators of CI
engines will need to combust low sulfur fuel no later than July 15
2006, instead of within 6 months of the
effective date of the rule revision. Engines that remain or intend to remain at the same location for 12
consecutive months or more and burn 10,000 gallons/year or more will need to control their emissions.
Under the draft rule, emissions needed to be controlled if (a) the engine either remained at the same
location for 12 months (no change) or operated at a seasonal source for two years (deleted in revised rule)
and (b) the engine, or an aggregation of engines, at that location burned 40,000 gallons/year or more
(replaced in revised rule with a single engine that burned 10,000 gallons per year).
The revised rule is modified to allow for increased ability to comply by using certified control devices as
an alternative to Best Available Control Technology Requirements. In addition, the compliance schedule
is simplified. The requirement to meet Best Available Control Technology for engine test facilities
burning over 40,000 gallons per year is not changed.
The code was sent to state lawmakers for approval. NR 445 was codified into State law during a February 24-25 2004 meeting. The state maintains a
website with further information on the rule change.
Most practical applications of onsite electrical generation will not require siting approval from the Wisconsin Public Service
Commission.
A power plant with a designed capacity of 100 MW or more must have a Certificate of Public Convenience and
Necessity (CPCN) from the Commission before plant-related construction may begin. In order to obtain the CPCN,
an application must be filed with the Commission, and the following instructions should be considered.
The state maintains a Requirements for Power Plant
and Power Line Development information site.

The state of Wisconsin released finalized interconnection standards in February 2004.
The Wisconsin Distributed Generation Interconnection Guidelines was developed in response to
Wisconsin Statute §196.496, relating to the development of rules for the interconnection of distributed generation
to electric providers. Wisconsin's cooperative electric utilities are not subject to §196.496, or the interconnection rules.
However, cooperative electric utilities are encouraged to adopt guidelines. The rule covers all distributed generation
facilitites 15 MW and less. Regulations pertaining to interconnection are codified in
Wisconsin
Public Service Commission Rule 119.
There are five categories of DG systems, based on capacity:
- Category 1--20 kW or less
- Category 2--20 kW to 200 kW
- Category 3--Greater than 200 kW to 1 MW
- Category 4--Greater than 1 MW to 15 MW
The proposed rules spell out a screening process similar to that used in other states. There are 11 possible
steps involved in the application process for all four DG categories:
- Generator submits application;
- Company conducts application review;
- Company conducts feasibility study;
- Applicant authorizes impact study;
- Company performs impact study;
- Applicant authorizes electric power system facility study;
- Company performs electric power system facility study;
- Applicant executes interconnection agreement, authorizes work and defrays costs;
- Project construction;
- Applicant completes commissioning, pre-parallel testing;
- Final acceptance, cost reconciliation, authorization to connect

The table below lists the number of days a utility may take to study the interconnection of DG.

Focus on Energy is a public-private partnership offering energy information and services to electric
utility customers in Wisconsin. The goals of this program are to encourage energy efficiency and use of
renewable energy, enhance the environment, and ensure the future supply of energy for Wisconsin. The
renewable energy program seeks to raise awareness, provide training and financing, enhance marketing,
promote technical assistance and support the installation of renewable energy technologies across
Wisconsin. The partnership provides a number of grant and incentive opportunities that are funded on a
first-come first-serve basis thorough December 2003.
Although the program seems geared predominately towards renewable energy systems, it appears as through
a CHP application co-firing with biomass would be eligible.
Implementation Grants provide financial support for the installation of commercially available
renewable energy systems that produce electricity and/or thermal energy. Implementation Grants
are for renewable energy systems that are larger than 20 kilowatts or that produce more than 5,000
therms annually.
Bioenergy systems can use solid, liquid or gaseous fuels from agricultural crops, landfill gas,
municipal sludge, paper mill sludge, and agricultural animal waste. Bioenergy systems cannot use
fuel from non-vegetation-based household, commercial or industrial waste. The bioenergy fuel can be
direct-fired, co-fired or gasified. The maximum Implementation Grant is based on an estimate of the
amount of electricity that the bioenergy system will produce in one year, plus an estimate of the
amount of utilized thermal energy that the bioenergy system will produce in one year:
Maximum Implementation Grant = 1,600 x [(rated capacity in kilowatts) x (capacity factor)]^0.63 + 30 x
(therms utilized per year)^0.63
where capacity factor is the fraction of time the renewable energy
system produces electricity during one year.

Implementation Grant Fact sheet or by contacting:
