(1)
(a) Upon application by any public utility providing electric, natural gas, or steam service, the
commission shall authorize such public utility to provide utility services to a specific customer
or potential customer by contract without reference to its tariffs on file with the commission if
the commission finds that:
(I) For contracts with a specific customer or potential customer involving electric and
steam service:
(A) The price of any such service is not below that service's variable cost;
(B) The customer, or potential customer, has expressed its intention to decline or
discontinue, or partially discontinue, service, to provide its own service, or to pursue the
purchase of alternate services from another provider;
(C) The approval of the application will not adversely affect the remaining customers of
the public utility; and
(D) The approval of the application is in the public interest;
(II) For contracts with existing customers involving natural gas service:
(A) The customer has the ability to provide its own service or has competitive
alternatives available from other providers of the same or substitutable service, except from
another public utility providing or proposing to provide the same type of service;
(B) The customer will discontinue using the services of the public utility if the
authorization is not granted;
(C) Approval of the application will not as adversely affect the remaining customers of
the public utility as would the alternative;
(D) The price of any such service provided pursuant to this subparagraph (II) shall be
justified and shall not be less than the marginal cost of the service to the public utility. If the
price is less than marginal cost, this shall be deemed to be an illegal restraint of trade subject to
the provisions of article 4 of title 6, C.R.S.; and
(E) The approval of the application is in the public interest.
(b) (I) Following a notice period of five days after the filing of an application under this
section, the commission shall approve or deny the application within thirty days. All applications
filed with the commission pursuant to this section shall be placed at the head of the commission's
docket and shall be disposed of promptly within the time periods set forth in this subsection
(1)(b)(I); except that, for good cause shown, the commission may extend the period in which it
must act for an additional fifteen days, or, in extraordinary circumstances, including the
existence of numerous pending applications under this section, the commission may extend the
period in which it must act for an additional thirty days beyond the fifteen days provided for in
this subsection (1)(b)(I).
(II) Whenever the application is continued as provided in subsection (1)(b)(I) of this
section, the commission shall enter an order making the continuance and stating fully the facts
necessitating the continuance. If the commission has not approved or denied an application
within the time periods set forth in subsection (1)(b)(I) of this section, the application shall be
deemed approved. If the commission denies an application for approval within the permitted
period, the subject contract does not become effective.
(III) Any contract submitted pursuant to this section shall be filed under seal and treated
as confidential by the commission; except that, at the time the applicant files an application or
contract with the commission, the applicant shall also furnish a copy of the application to any
public utility then providing electric, gas, or steam service in the state of Colorado to the
customer, and also furnish a copy to the office of the utility consumer advocate, which office
shall also treat the contract as confidential.
(c) An application filed by a public utility pursuant to this section shall contain the name
of the customer, a description of the services proposed to be provided under contract, evidence
that the requirements of paragraph (a) of this subsection (1) have been met, and any additional
information required by the commission. The commission may dismiss an application if the
applicant fails to provide information necessary to enable the commission to make the findings
required by paragraph (a) of this subsection (1).
(d) (Deleted by amendment, L. 92, p. 2138, § 1, effective April 23, 1992.)
(e) Within ten days after the execution of the contract, the public utility shall file with
the commission under seal and as a confidential document the final contract or other description
of the price and terms of service, together with any additional information required by the
commission. The applicant shall also furnish a copy of the information to the office of the utility
consumer advocate, which office shall treat the information as confidential. The commission has
no authority to disapprove the contract if the contract complies with the conditions contained in
subsection (1)(a) of this section, but the commission may consider the contract for general
regulatory purposes and to ensure compliance with the requirements of this section.
(2) (a) For contracts involving electric and steam service, at the time of any proceeding
in which a utility's overall rate levels are determined, the commission shall specify a fully
distributed cost methodology to be used to segregate rate base, expenses, and revenues
associated with utility service provided by contract pursuant to this section from other regulated
utility operations. For contracts involving electric and steam service, if revenues from a service
provided pursuant to this section are less than the cost of service as determined by the fully
distributed cost methodology specified by the commission, the rates of other regulated utility
operations may not be increased to recover such difference between costs and revenues.
(b) For contracts involving natural gas service, the commission may require a public
utility to segregate investments, expenses, and revenues associated with utility service provided
pursuant to subparagraph (II) of paragraph (a) of subsection (1) of this section to ensure that
such services are not subsidized by revenues from other utility operations. If the commission
requires such segregation of such investment and expenses, it shall specify a fully distributed
cost allocation methodology.
(3) (a) This section shall neither enlarge nor diminish the rights and obligations of a
public utility operating under a certificate issued by the commission to serve customers within a
territory pursuant to the provisions of article 3.5, 5, or 9.5 of this title.
(b) Nothing in this section shall be construed to permit any public utility to provide
electric, natural gas, or steam service to a customer of another public utility located in or for use
in the service territory of such other public utility providing or proposing to provide the same
type of service.
(4) (a) The commission has the right to inspect the books and records of any affiliate of a
public utility to the extent that the affiliate uses any plant, or incurs any cost, or provides any
service or product which is joint and common to the provision of public utility services and
products subject to the jurisdiction of the commission. Upon application and for good cause
shown, the commission may enter an appropriate protective order which directs the manner in
which proprietary information shall be treated.
(b) For purposes of this subsection (4), unless the context otherwise requires, "affiliate of
a public utility" means a subsidiary of a public utility, a parent corporation of a public utility, a
joint venture organized as a separate corporation or partnership to the extent of the individual
public utility's involvement with the joint venture, or a subsidiary of a parent corporation of a
public utility.
(5) Nothing in this section limits or restricts the commission's authority to regulate rates
and charges, correct abuses, or prevent unjust discrimination except as specifically provided in
this section.
(6) (a) Notwithstanding any other provision of this section, an investor-owned electric
utility subject to rate regulation by the commission may offer economic development rates to a
qualifying commercial or industrial customer.
(b) (I) An economic development rate approved pursuant to this section must be lower
than the rate or rates that the qualifying commercial or industrial customer would be or currently
is subject to under the utility's tariffs in effect at the time the qualifying commercial or industrial
customer seeks to qualify for the economic development rate; except that an economic
development rate must not be lower than the utility's marginal cost of providing service to the
qualifying commercial or industrial customer.
(II) (A) The commission may approve investor-owned utility tariffs that provide for
implementation of an economic development rate and set a minimum and maximum amount for
the rate consistent with subsection (6)(b)(I) of this section.
(B) Notwithstanding subsection (6)(b)(II)(A) of this section, the utility may negotiate
and enter into agreements related to economic development rates with individual qualifying
commercial or industrial customers without commission approval so long as the agreed-upon
economic development rate complies with the commission-approved tariff and the addition or
expansion of existing load at a single location is less than or equal to twenty megawatts. Any
addition or expansion of existing load at a single location that is greater than twenty megawatts
requires separate commission approval based upon a finding that the addition or expansion is
consistent with this section.
(III) An investor-owned utility may offer an economic development rate to a qualifying
commercial or industrial customer for up to ten years.
(c) (I) An authorization granted by the commission pursuant to this section must include
such terms and conditions as the commission determines are necessary to ensure that the
economic development rates or charges assessed to other customers do not subsidize the cost of
providing service to qualifying commercial and industrial customers consistent with subsection
(6)(b)(I) of this section, and that there is no other subsidization of such service. In developing the
terms and conditions, the commission shall consider, among other things, the rates and charges
assessed to the utility's wholesale customers and the effects on other transmission system owners
and users resulting from new transmission facilities constructed in connection with the utility's
expansion of an existing voluntary renewable energy program or service offering.
(II) In a commission proceeding related to economic development rates authorized
pursuant to subsection (6)(b) of this section, the utility bears the burden of proof to establish that:
(A) The rates or charges assessed to other customers do not subsidize the cost of
providing economic development rates to qualifying commercial or industrial customers;
(B) The rates of other regulated utility operations do not increase; and
(C) Other customers on the utility's system do not experience a rate increase due to a rate
or rates offered to a qualifying commercial or industrial customer pursuant to this section.
(III) The commission shall not impute to the utility revenues that would have been
received from the qualifying commercial or industrial customer if the customer were being
provided service under the corresponding rate for which it would have otherwise qualified under
the utility's tariffs.
(d) (I) An investor-owned utility may seek commission approval to expand any
voluntary renewable energy program or service offering, except those covered by valid
agreements to the contrary executed and approved by the commission as of January 1, 2019,
through the acquisition of additional renewable generation capacity and energy to meet the
current and projected demand of:
(A) Any commercial or industrial customer making a capital investment of two hundred
fifty million dollars or more;
(B) Any commercial or industrial customer that requires such expansion to remain as a
customer of that utility; or
(C) Any qualifying commercial or industrial customer entering the service territory of
the utility.
(II) The commission may approve, within one hundred twenty days, an expansion of an
existing voluntary renewable energy program or service offering upon a showing by the utility
that:
(A) There is not sufficient capacity and energy in the existing voluntary renewable
energy program or service offering to satisfy the needs of the customer and the customer meets
the requirements of subsection (6)(d)(I) of this section; and
(B) The availability of the program or service, either on its own or in combination with
other incentives, is a substantial factor in the customer's decision to locate new or expand or
retain existing business operations in Colorado.
(7) As used in subsection (6) of this section and this subsection (7):
(a) "Qualifying commercial or industrial customer":
(I) Means a utility customer that:
(A) Agrees to: Locate commercial or industrial operations in Colorado and add at least
three megawatts of new load at a single location; or expand existing commercial or industrial
operations in Colorado and add at least three megawatts of new load at a single location; and
(B) Demonstrates, to the satisfaction of the investor-owned utility, subject to review by
the commission, that: The cost of electricity is a critical consideration in deciding where to
locate new or expand existing operations; and the availability of economic development rates,
either on their own or in combination with other economic development incentives, is a
substantial factor in the customer's decision to locate new or expand existing business operations
in Colorado;
(II) Does not include a customer that agrees to relocate or otherwise transfer its existing
load of at least three megawatts from the service territory of another public utility, as defined in
section 40-1-103, into the service territory of the utility offering economic development rates.
(b) "Voluntary renewable energy program or service offering" means a program or other
service offering approved by the commission that allows a commercial or industrial customer
access to eligible energy resources, as that term is defined in section 40-2-124 (1)(a), on a
voluntary basis, on terms and conditions deemed necessary by the commission. For a voluntary
renewable energy program or service offering to be expanded, it must have been approved by the
commission prior to the expansion request of a commercial or industrial customer pursuant to
subsection (6)(d)(I) of this section.
(8) This subsection (8) and subsections (6) and (7) of this section are repealed, effective
January 1, 2028.
