Sec. 16-108.16. Commercial Rate Impacts.

(a) Each electric utility that serves more than 500,000 retail customers in the State shall file with the Commission the reports required by this Section, which shall identify the annual average increases due to future energy investment costs for the applicable period or periods in electric bills to commercial and industrial retail customers. For purposes of this Section, "commercial and industrial retail customers" means non-residential retail customers other than those customers who are exempt from subsections (a) through (j) of Section 8-103B of this Act under subsection (l) of Section 8-103B.

(b) The increase determination required by subsection (a) of this Section shall be based on a calculation comprised of the following components:

(1) Beginning with the 2017 calendar year, the average annual amount paid by commercial and industrial retail customers, expressed on a cents-per-kilowatthour basis, to recover future energy investment costs, which include the charges to recover the costs incurred by the utility under the following provisions:

(A) Sections 8-103, Section 8-103B, and 16-111.5B of this Act, as applicable, and as such costs may be recovered under Sections 8-103, 8-103B, 16-111.5B or Section 16-108.5 of this Act;

(B) subsection (d-5) of Section 1-75 of the Illinois Power Agency Act, as such costs may be recovered under subsection (k) of Section 16-108 of this Act; and

(C) Section 16-107.6 of this Act.

Beginning with the 2018 calendar year, each of the average annual charges calculated in subparagraphs (A) through (C) of this paragraph (1) shall be equal to the average of each such charge applied over a period that commences with the calendar year ending December 31, 2017 and ends with the most recently completed calendar year prior to the calculation or calculations required by this Section.

(2) The sum of the following:

(A) annual net energy savings to commercial and industrial retail customers that are attributable to the implementation of voltage optimization measures under Section 8-103B of this Act, expressed on a cents-per-kilowatthour basis, which are estimated energy and capacity benefits for commercial and industrial retail customers minus the measure costs recovered from those customers, divided by the average annual kilowatt-hour consumption of commercial and industrial retail customers; notwithstanding this subparagraph (A), a utility may elect not to include an estimate of net energy savings as described in this subparagraph (A), in which case the value under this subparagraph (A) shall be zero;

(B) the average annual cents-per-kilowatthour charge applied under Section 8-103 of this Act to commercial and industrial retail customers during calendar year 2016 to recover the costs authorized by such Section; and

(C) incremental energy efficiency savings, which shall be calculated by subtracting the value determined in item (ii) of this subparagraph (C) from the value determined in item (i) of this subparagraph and dividing the difference by the value identified in item (iii) of this subparagraph:

(i) Total value, in dollars, of the cumulative persisting annual saving achieved from the installation or implementation of all energy efficiency measures for commercial and industrial retail customers under Sections 8-103, 8-103B and 16-111.5 of this Act, net of the cumulative annual percentage savings in kilowatt-hours, if any, calculated under subparagraph (A) of this paragraph (2).

(ii) 2016 value, which shall equal the value calculated under item (i) of this subparagraph (C) multiplied by the quotient of (aa) the cumulative persisting annual savings, in kilowatt-hours, achieved from the installation or implementation of all energy efficiency measures for commercial and industrial retail customers under Sections 8-103, 8-103B and 16-111.5B of this Act as of December 31, 2016, divided by (bb) the cumulative persisting annual savings, in kilowatt-hours, from the installation or implementation of all energy efficiency measures for commercial and industrial retail customers under Sections 8-103, 8-103B and 16-111.5 of this Act, net of the cumulative annual percentage savings in kilowatt-hours, if any, calculated under subparagraph (A) of this paragraph (2).

(iii) The average annual kilowatt-hour consumption of those commercial and industrial retail customers that installed or implemented energy efficiency measures under energy efficiency programs or plans approved pursuant to Sections 8-103, 8-103B or 16-111.5B of this Act.

Beginning with the 2018 calendar year, each of the values identified in subparagraphs (A) and (C) of this paragraph (2) shall be equal to the average of each such value during a period that commences with the calendar year ending December 31, 2017 and ends with the most recently completed calendar year prior to the calculation or calculations required by this Section.

For purposes of this Section, cumulative persisting annual savings shall have the meaning set forth in Section 8-103B of this Act, and energy efficiency measures shall have the meaning set forth in Section 1-10 of the Illinois Power Agency Act.

(c)(1) No later than June 30, 2017, and every June 30 thereafter until June 30, 2027, an electric utility subject to this Section shall submit a report to the Commission that sets forth the utility's 10-year projection of the values of each of the components described in paragraphs (1) and (2) of subsection (b) of this Section. Each utility's report to the Commission shall identify the result of the computation performed under this Section for the immediately preceding calendar year and update its 10-year projection. Such calculations shall be performed by subtracting the sum of paragraph (2) of subsection (b) of this Section from the sum of paragraph (1) of such subsection (b).

In the event that the actual or projected average annual increase for commercial and industrial retail customers exceeds 1.3% of 8.90 cents-per-kilowatthour, which is the average amount paid per kilowatt-hour for electric service during the year ending December 31, 2015 by Illinois commercial retail customers, as reported to the Edison Electric Institute, then the applicable utility shall comply with the provisions of paragraphs (2) through (4) of this subsection (c), as applicable.

(2) In the event that the projected average annual increase for commercial and industrial retail customers during a calendar year exceeds the applicable limitation set forth in paragraph (1) of this subsection (c), then the utility shall comply with the following provisions, as applicable:

(A) If an exceedance is projected during the first four calendar years of the 10-year projection, then the utility shall include in its report submitted under paragraph (1) of this subsection (c) the utility's proposal or proposals to decrease the future energy investment costs described in paragraph (1) of subsection (b) of this Section to ensure that the limitation set forth in such paragraph (1) is not exceeded. The Commission shall, after notice and hearing, enter an order directing the utility to implement one or more proposals, as such proposals may be modified by the Commission. The Commission shall have the authority under this subparagraph (A) to approve modifications to the contracts executed under subsection (d-5) of Section 1-75 of the Illinois Power Agency Act. If the Commission approves modifications to such contracts that are in an amount that reduces the quantities to be procured under such contracts by more than 7%, then the supplier shall have the option of accepting the modifications or terminating the modified contract or contracts, subject to the termination requirements and notice provisions set forth in item (i) of subparagraph (B) of paragraph (4) of this Section.

(B) If an exceedance is projected during any calendar year during the last 6 years of the 10-year projection, then the utility shall demonstrate in its report submitted under paragraph (1) of this subsection (c) how the utility will reduce the future energy investment costs described in paragraph (1) of subsection (b) of this Section to ensure that the limitation set forth in such paragraph (1) is not exceeded.

(3) If the actual average annual increase for commercial and industrial retail customers during a calendar year exceeded the limitation set forth in paragraph (1) of this subsection (c), then the utility shall prepare and file with the Commission, at the time it submits its report under paragraph (1) of this subsection (c), a corrective action plan. The Commission shall initiate an investigation to determine the factors that contributed to the actual average annual increase exceeding such limitation for the applicable calendar year, and shall, after notice and hearing, enter an order approving, or approving with modification, the utility's corrective action plan within 120 days after the utility files such plan. The Commission shall also submit a report to the General Assembly no later than 30 days after it enters such order, and the report shall explain the results of the Commission's investigation and findings and conclusions of its order.

(4) If the actual average annual increase for commercial and industrial retail customers during a calendar year exceeds the limitation set forth in paragraph (1) of this subsection (c) for two consecutive years, then the utility shall indicate in its report filed under paragraph (1) of this subsection (c) whether the utility will proceed with or terminate the future energy investments described and authorized under subsection (d-5) of the Illinois Power Agency Act and Sections 8-103B and 16-107.6 of this Act. The utility's election shall be subject to the requirements of subparagraph (A) or (B) of this paragraph (4), as applicable.

(A) If the utility elects to proceed with the future energy investments, then it shall be subject to the corrective action plan requirements set forth in paragraph (3) of this subsection (c). In addition, the utility must commit to apply a credit to commercial and industrial retail customers' bills if the actual average annual increase for such customers exceeds the limitation set forth in paragraph (1) of this subsection (c) for the year in which the utility files its corrective action plan, which credit shall be in an amount that equals the portion by which the increase exceeds such limitation. The Commission shall initiate an investigation to determine the factors that contributed to the actual average annual increase exceeding such limitation for the applicable calendar year, including an analysis of the factors contributing to the limitation being exceeded for two consecutive years, and shall, after notice and hearing, enter an order approving, or approving with modification, the utility's corrective action plan within 120 days after the utility files such plan. The Commission shall also submit a supplemental report to the General Assembly no later than 30 days after it enters such order, and the report shall explain the results of the Commission's investigation and findings and conclusions of its order.

(B) If the utility elects to terminate future energy investments, then the Commission shall, notwithstanding anything to the contrary:

(i) Order the utility to terminate the contract or contracts executed under subsection (d-5) of Section 1-75 of the Illinois Power Agency Act, pursuant to the contract termination provisions set forth in such subsection (d-5), provided that notice of such termination must be made at least 3 years and 75 days prior to the effective date of such termination. In the event that only a portion of the contracts executed under such subsection (d-5) are terminated for a particular zero emission facility, then the zero emission facility may elect to terminate all of the contracts executed for that facility under such subsection (d-5).

(ii) Within 30 days of the utility's report identifying its election to terminate future energy investments, initiate a proceeding to approve the process for terminating future expenditures under Sections 16-107.6 of the Public Utilities Act. The Commission shall, after notice and hearing, enter its order approving such process no later than 120 days after initiating such proceeding.

(iii) Within 30 days of the utility's report identifying its election to terminate future energy investments, initiate a proceeding under Section 8-103B of this Act to reduce the cumulative persisting annual savings goals previously approved by the Commission under such Section to ensure just and reasonable rates. The Commission shall, after notice and hearing, enter its order approving such goal reductions no later than 120 days after initiating such proceeding.

Notwithstanding the termination of future energy investments pursuant to this subparagraph (B), the utility shall be permitted to continue to recover the costs of such investments that were incurred prior to such termination, including but not limited to all costs that are recovered through regulatory assets created under Sections 8-103B and 16-107.6 of this Act. Nothing in this Section shall limit the utility's ability to fully recover such costs. The utility shall also be permitted to continue to recover the costs of all payments made under contracts executed under subsection (d-5) until the effective date of the contract's termination.

(5) Notwithstanding anything to the contrary, if, under this Section or subsection (m) of Section 16-108 of this Act, modifications to the contracts executed under subsection (d-5) of Section 1-75 of the Illinois Power Agency Act are, in total, in an amount that reduces the quantities to procured under such contracts by more than 10%, then the supplier shall have the option of accepting the modifications or terminating the modified contract or contracts, subject to the termination requirements and notice provisions set forth in item (i) of subparagraph (B) of paragraph (4) of this Section.
