A bill for an act
relating to energy; allowing inclusion of supply-side savings in meeting
conservation improvement goals; amending Minnesota Statutes 2014, section
216B.241, subdivisions 1, 1c, 10.

BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF MINNESOTA:

Section 1.

Minnesota Statutes 2014, section 216B.241, subdivision 1, is amended to
read:

Subdivision 1.

Definitions.

For purposes of this section and section 216B.16,
subdivision 6b, the terms defined in this subdivision have the meanings given them.

(a) "Commission" means the Public Utilities Commission.

(b) "Commissioner" means the commissioner of commerce.

(c) "Department" means the Department of Commerce.

(d) "Energy conservation" means demand-side new text begin or supply-side new text end management of energy
supplies resulting in a net reduction in energy use. Load management that reduces overall
energy use is energy conservation.

(e) "Energy conservation improvement" means a project that results in energy
efficiency or energy conservation. Energy conservation improvement may include waste
heat that is recovered and converted into electricity deleted text begin , but does not include electric utility
infrastructure projects approved by the commission under section 216B.1636 deleted text end . Energy
conservation improvement also includes waste heat recovered and used as thermal energy.

(f) "Energy efficiency" means measures or programs, including energy conservation
measures or programs, that target consumer behavior, equipment, processes, or devices
designed to produce either an absolute decrease in consumption of electric energy or natural
gas or a decrease in consumption of electric energy or natural gas on a per unit of production
basis without a reduction in the quality or level of service provided to the energy consumer.

(g) "Gross annual retail energy sales" means annual electric sales to all retail
customers in a utility's or association's Minnesota service territory or natural gas
throughput to all retail customers, including natural gas transportation customers, on a
utility's distribution system in Minnesota. For purposes of this section, gross annual
retail energy sales exclude:

(1) gas sales to:

(i) a large energy facility;

(ii) a large customer facility whose natural gas utility has been exempted by the
commissioner under subdivision 1a, paragraph (b), with respect to natural gas sales made
to the large customer facility; and

(iii) a commercial gas customer facility whose natural gas utility has been exempted
by the commissioner under subdivision 1a, paragraph (c), with respect to natural gas sales
made to the commercial gas customer facility; and

(2) electric sales to a large customer facility whose electric utility has been exempted
by the commissioner under subdivision 1a, paragraph (b), with respect to electric sales
made to the large customer facility.

(h) "Investments and expenses of a public utility" includes the investments
and expenses incurred by a public utility in connection with an energy conservation
improvement, including but not limited to:

(1) the differential in interest cost between the market rate and the rate charged on a
no-interest or below-market interest loan made by a public utility to a customer for the
purchase or installation of an energy conservation improvement;

(2) the difference between the utility's cost of purchase or installation of energy
conservation improvements and any price charged by a public utility to a customer for
such improvements.

(i) "Large customer facility" means all buildings, structures, equipment, and
installations at a single site that collectively (1) impose a peak electrical demand on an
electric utility's system of not less than 20,000 kilowatts, measured in the same way as the
utility that serves the customer facility measures electrical demand for billing purposes or
(2) consume not less than 500 million cubic feet of natural gas annually. In calculating
peak electrical demand, a large customer facility may include demand offset by on-site
cogeneration facilities and, if engaged in mineral extraction, may aggregate peak energy
demand from the large customer facility's mining and processing operations.

(j) "Large energy facility" has the meaning given it in section 216B.2421,
subdivision 2, clause (1).

(k) "Load management" means an activity, service, or technology to change the
timing or the efficiency of a customer's use of energy that allows a utility or a customer to
respond to wholesale market fluctuations or to reduce peak demand for energy or capacity.

(l) "Low-income programs" means energy conservation improvement programs that
directly serve the needs of low-income persons, including low-income renters.

(m) "Qualifying utility" means a utility that supplies the energy to a customer that
enables the customer to qualify as a large customer facility.

(n) "Waste heat recovered and used as thermal energy" means capturing heat energy
that would otherwise be exhausted or dissipated to the environment from machinery,
buildings, or industrial processes and productively using such recovered thermal energy
where it was captured or distributing it as thermal energy to other locations where it is
used to reduce demand-side consumption of natural gas, electric energy, or both.

(o) "Waste heat recovery converted into electricity" means an energy recovery
process that converts otherwise lost energy from the heat of exhaust stacks or pipes used
for engines or manufacturing or industrial processes, or the reduction of high pressure
in water or gas pipelines.

Sec. 2.

Minnesota Statutes 2014, section 216B.241, subdivision 1c, is amended to read:

Subd. 1c.

Energy-saving goals.

(a) The commissioner shall establish energy-saving
goals for energy conservation improvement expenditures and shall evaluate an energy
conservation improvement program on how well it meets the goals set.

(b) Each individual utility and association shall have an annual energy-savings
goal equivalent to 1.5 percent of gross annual retail energy sales unless modified by the
commissioner under paragraph (d). The savings goals must be calculated based on the
most recent three-year weather-normalized average. A utility or association may elect to
carry forward energy savings in excess of 1.5 percent for a year to the succeeding three
calendar years, except that savings from electric utility infrastructure projects allowed
under paragraph (d) may be carried forward for five years. A particular energy savings can
be used only for one year's goal.

(c) The commissioner must adopt a filing schedule that is designed to have all
utilities and associations operating under an energy-savings plan by calendar year 2010.

(d) In its energy conservation improvement plan filing, a utility or association may
request the commissioner to adjust its annual energy-savings percentage goal based on
its historical conservation investment experience, customer class makeup, load growth, a
conservation potential study, or other factors the commissioner determines warrants an
adjustment. The commissioner may not approve a plan of a public utility that provides for
an annual energy-savings goal of less than one percent of gross annual retail energy sales
from energy conservation improvements.

A utility or association may include in its energy conservation plan energy savings
from electric utility infrastructure projects approved by the commission under section
216B.1636 or waste heat recovery converted into electricity projects that may count as
energy savings deleted text begin in addition to a minimum energy-savings goal of at least one percent for
energy conservation improvements deleted text end . Electric utility infrastructure projects must result in
increased energy efficiency greater than that which would have occurred through normal
maintenance activity.

(e) An energy-savings goal is not satisfied by attaining the revenue expenditure
requirements of subdivisions 1a and 1b, but can only be satisfied by meeting the
energy-savings goal established in this subdivision.

(f) An association or utility is not required to make energy conservation investments
to attain the energy-savings goals of this subdivision that are not cost-effective even
if the investment is necessary to attain the energy-savings goals. For the purpose of
this paragraph, in determining cost-effectiveness, the commissioner shall consider the
costs and benefits to ratepayers, the utility, participants, and society. In addition, the
commissioner shall consider the rate at which an association or municipal utility is
increasing its energy savings and its expenditures on energy conservation.

(g) On an annual basis, the commissioner shall produce and make publicly available
a report on the annual energy savings and estimated carbon dioxide reductions achieved
by the energy conservation improvement programs for the two most recent years for
which data is available. The commissioner shall report on program performance both in
the aggregate and for each entity filing an energy conservation improvement plan for
approval or review by the commissioner.

(h) By January 15, 2010, the commissioner shall report to the legislature whether
the spending requirements under subdivisions 1a and 1b are necessary to achieve the
energy-savings goals established in this subdivision.

Sec. 3.

Minnesota Statutes 2014, section 216B.241, subdivision 10, is amended to read:

Subd. 10.

Waste heat recovery; thermal energy distribution.

Demand-side new text begin or
supply-side new text end natural gas or electric energy displaced by use of waste heat recovered and
used as thermal energy, including the recovered thermal energy from a cogeneration or
combined heat and power facility, is eligible to be counted towards a utility's natural gas
or electric energy savings goals, subject to department approval.
