Triennial Compliance Filing or Next Annual )
Update Report )
A provision in the Commission’s electric utility resource planning rule, 4 CSR 240-22.080(4), requires Missouri’s electric utilities to consider and analyze special contemporary issues in their integrated resource plan (IRP) triennial compliance filings or in their annual IRP update reports. The regulation provides that by September 15 of each year, Staff, Public Counsel, and other interested parties may file suggested issues for consideration. The regulation allows the utilities and other parties until October 1 to file comments regarding the suggested issues. The Commission must then issue an order by November 1 of each year specifying the list of special contemporary issues that each electric utility must address.
The Commission’s Staff, the Missouri Department of Economic Development – Division of Energy, and the Sierra Club filed suggested special contemporary issues for Union Electric Company d/b/a Ameren Missouri to analyze and respond to in its 2016 IRP annual update filing. Ameren Missouri filed responses to those suggestions, as did United for Missouri. The Commission must now determine what special contemporary issues Ameren Missouri should address.
This is not a contested case. The Commission does not need to hear evidence before reaching a decision and does not need to make findings of fact and conclusions of law in announcing that decision.[1] The Commission’s rule gives the Commission broad discretion in determining what issues a utility should be required to address, indicating:
[t]he purpose of the contemporary issues lists is to ensure that evolving regulatory, economic, financial, environmental, energy, technical, or customer issues are adequately addressed by each utility in its electric resource planning. Each special contemporary issues list will identify new and evolving issues but may also include other issues such as unresolved deficiencies or concerns from the preceding triennial compliance filing.[2]
After considering these factors, the Commission will adopt the list of special contemporary issues set forth in this order. The Commission has chosen these issues because they are of particular interest and importance and should be addressed in Ameren Missouri’s IRP filing. Ameren Missouri may already plan to address these issues in its IRP annual update filing apart from their designation as special contemporary issues. Or it may believe that it has already adequately addressed some of these issues in a previous IRP filing. If that is so, then it does not need to undertake any additional analysis because of this designation and may simply point the Commission to that analysis in its IRP filing.
THE
COMMISSION ORDERS THAT:
1. Ameren Missouri shall analyze and document the following special contemporary issues in its 2016 Integrated Resource Plan annual update filing:
a. Review
the impact of foreseeable emerging energy efficiency technologies throughout
the 20-year planning period;
b. Review the impact of foreseeable emerging
energy storage technologies throughout the 20-year planning period;
c. Analyze and document the future capital
and operating costs faced by each Ameren Missouri coal-fired generating unit in
order to comply with the following environmental standards:
(1)
Clean Air Act New Source Review provisions;
(2)
1-hour Sulfur Dioxide National Ambient Air
Quality Standard;
(3)
National Ambient Air Quality Standards for
ozone and fine particulate matter;
(4)
Cross-State Air Pollution Rule, including the
anticipated 2016 update to the rule to incorporate interstate transport
requirements for the 2008 ozone National Ambient Air Quality Standard;
(5)
Clean Air Interstate Rule;
(6)
Mercury and Air Toxics Standards;
(7)
Clean Water Act Section 316(b) Cooling Water
Intake Standards;
(8)
Clean Water Act Steam Electric Effluent
Limitation Guidelines;
(9)
Coal Combustion Waste rules;
(10)
Clean Air Act Section 111(d) Greenhouse Gas
standards for existing sources;
(11)
Clean Air Act Regional Haze requirements; and
(12)
Clean Power Plan.
d. Analyze and document the cost of any
transmission grid upgrades or additions needed to address transmission grid
reliability, stability, or voltage support impacts that could result from the
retirement of any existing Ameren Missouri coal-fired generating unit in the
time period established in the IRP process.
e. Analyze and document the range of
potential levels of distributed generation in Ameren Missouri’s service
territory for the 20-year planning horizon and the potential impacts of each
identified level of distributed generation, and in particular distributed solar
generation, on Ameren Missouri’s preferred resource plan. The potential impacts should quantify both
the amount of electrical energy the distributed generation is expected to
provide to the grid and the amount of electrical energy that the distributed
generation customers are expected to consume on site that will offset the
amount that the company would normally provide to those customers.
f. Review the options available to Ameren
Missouri for providing customer financing for energy efficiency measures. Discuss Ameren Missouri’s current, near term
(next three years) and long-term activities and plans for providing customer
financing for energy efficiency measures.
g. Describe how the preferred plan of the
Company’s last and current annual or triennial Integrated Resource Plans (IRPs)
positions the utility for full or partial compliance with the U.S.
Environmental Protection Agency’s (EPA) Clean Power Plan (CPP) under Section
111(d) of the Clean Air Act, as released in final form on August 3, 2015. Please include in this regard:
(1). An evaluation of how renewable energy,
energy efficiency and other demand-side resources (including combined heat and
power) deployed by the Company after January 1, 2013 could contribute to
compliance;
(2). An
evaluation of how renewable energy and energy efficiency and other demand-side
resources (including combined heat and power) deployed by the Company after the
submission of a final State Implementation Plan could qualify under EPA’s
proposed Clean Energy Investment Program (CEIP);
(3). A description of additional investments
(in fiscal, capacity, and energy terms by year) which will be required by the
Company to meet the targets in the CPP under scenarios including: a statewide
rate-based or mass-based emissions goal; a “trading-ready” approach; and
participation in the CEIP;
(4). The barriers to achieving these
additional investments;
(5). The price of carbon used by the Company
in the analyses above; and
(6). An
indication of the Company’s preferences regarding various compliance options
under a state implementation plan.
h. Describe any assessment of the value of
solar (VOS) performed or used by the Company specifically for its Missouri
service territory.
i. Analyze and document the cost of any
transmission grid upgrades or additions needed to address transmission grid
reliability, stability, or voltage support impacts that could result from the
retirement of any existing Ameren Missouri coal-fired generating unit.
j. Analyze and document cost and
performance information sufficient to fairly analyze and compare utility scale
wind and solar resources, including distributed generation, to other
supply-side alternatives.
k. Analyze the impact of emerging energy
efficiency technologies throughout the planning period.
2. This order shall become effective on November 1, 2015.
