MISO Filed Comments to EPA on Proposed Federal Plan

[vc_row][vc_column][vc_column_text]With the final Clean Power Plan released in October 2015, MISO continues to study the rule and work with stakeholders as states develop compliance plans.  As part of that education, MISO submitted comments to EPA to help inform the agency as it develops the Federal Plan rules.  The Federal Plan is a compliance plan that states can use as a model for developing their own plans; additionally, EPA will impose the federal plan on any state without an approved state plan.

The federal plan plays a major role in providing guidance to the states around compliance.  Our comments are designed to ensure that the EPA take steps to ensure reliability in their proposal.

The Honorable Gina McCarthy


U.S. Environmental Protection Agency

1200 Pennsylvania Avenue, NW

Washington, DC 20460


Attn: Docket ID No. EPA-HQ-OAR-2015-0199


Dear Administrator McCarthy:

The Midcontinent Independent System Operator, Inc. (MISO) submits the following comments

on the U.S. Environmental Protection Agency’s proposed rule to adopt federal plan

requirements and model trading rules for carbon emissions from existing electric generating



MISO is an independent, not-for-profit organization established to promote the common good

and general welfare through reliable and efficient delivery of electricity. We maintain reliable

operation of more than 65 thousand miles of electric transmission lines in 15 U.S. States and

the Canadian province of Manitoba. We provide open access to all users of the electric

transmission system on a non-discriminatory basis. MISO ensures reliability through

coordinated regional economic dispatch of power plants and forward-looking planning.


As a reliability coordinator for a large area in North America, MISO has a responsibility to

assess how environmental compliance and other requirements could impact electric system

reliability. It is for this reason that MISO submitted comments on EPA’s proposed rule to

establish carbon emission guidelines for existing electric generating units. We acknowledge

EPA’s efforts to address electric system reliability in the final carbon emission guidelines rule.

However, reliable implementation of the final rule still requires swift action and ongoing

coordination with multiple parties in order to plan for and install new infrastructure necessary

for compliance within the tight timelines outlined in the final rule. We also urge EPA to

establish the same reliability features in the final federal plan rules as it provided in the final

carbon emissions guidelines rule.


Significant Action is Needed to Accomplish Reliable Implementation

The Clean Power Plan will drive substantial changes to the energy resources used across our

footprint. In our comments on EPA’s proposed rule to establish carbon emission guidelines

for existing electric generating units, MISO urged EPA to provide sufficient time and to give

States flexibility to design compliance strategies that preserve reliability and ensure efficient

outcomes. While not every state may require a major infrastructure build out, for those that

do, it will take time to plan, approve, construct and place into service the new generation,

electric transmission facilities and natural gas infrastructure necessary to support electric

system reliability. For example, MISO’s experience indicates that installation of new electric

system transmission often requires lead times of six to ten years. Larger regional transmission

projects focusing on cost-effective delivery of renewable generation can take more than ten

years due to the scope and scale of the planning, approval and construction efforts. New

natural gas infrastructure may be needed and could demand comparable timeframes for

construction (four to six plus years).


Even with the final rule’s additional time and more gradual glide path, the timeline to prepare

for compliance is very tight between when State or federal plans are in place and when the

interim compliance period begins. States, utilities, and reliability and planning authorities

could be significantly challenged to undertake this immense effort in the time necessary to

achieve compliance while maintaining reliability. We urge EPA to work with a variety of

entities – State environmental and economic regulators and policy makers, utilities,

environmental and electric reliability federal agencies, and regional electric reliability and

planning authorities – to quickly identify and remove obstacles standing in the path to reliable

implementation of the carbon emission guidelines. Concurrently, MISO will work with its

stakeholders to explore ways to expedite the process of identifying and ultimately placing into

service the transmission infrastructure needed for continued reliable operation of the grid.


Consider Reliability When Proposing to Issue a Federal Plan for a State

The final federal plan rules should incorporate a reliability review process prior to imposing a

federal plan on a State. The final carbon emission guidelines rule requires States to

demonstrate that the reliability of the electrical grid has been considered as part of the

development of State plans. In the preamble to the proposed federal plan rules, EPA states

that it is considering reliability in development of the federal plan. However, it appears that

EPA is limiting its reliability consideration to issuance of the federal plan rules. MISO requests

that EPA establish a process in the final federal plan rules to consider reliability at the time it

proposes to impose a federal plan on a State. Such a process would allow a meaningful casespecific

review of reliability that is comparable to the State plan requirement.

EPA is proposing to allow itself up to 12 months to issue a federal plan for a State. During this

time, EPA should work with the relevant planning authorities for the State to review federal

plan impacts on reliability at the local, State and regional levels. Maintaining reliability is a

sensitive undertaking, involving case-specific and localized factors that may not respect State

boundaries. A reliability review during the process of issuing a federal plan will allow

consideration of the interactions of that plan with the approaches in the surrounding States

and region. This approach will minimize the potential for unanticipated consequences.

Additionally, EPA should consider the availability of functioning carbon trading markets. A

trading ready plan is only as good as the trading options that exist to facilitate the ability to

obtain allowances or credits, especially if they are needed to manage a reliability issue.

Appropriate considerations include the accessibility and liquidity of carbon trading products.

The success of a federal plan to reliably achieve compliance will depend upon the ability to

broadly trade allowances or credits. To facilitate the broadest possible market, EPA also

should not foreclose the opportunity to develop methods to allow trading between rate-based

and mass-based plans while still achieving compliance objectives. This would increase the

potential for a robust trading market, which should reduce costs to consumers and facilitate

reliable implementation of the rules.


Authorize Use of the Reliability Safety Valve in the Federal Plans

At the urging of many commenters, including MISO, EPA included a reliability safety valve

provision in the final carbon emission guidelines rule. Although EPA stated its expectation

that the circumstances warranting use of the reliability safety valve would be “extremely rare,”

it agreed that such a mechanism is prudent. For these same reasons, MISO requests that EPA

allow use of a reliability safety valve in the final federal plan rules.


EPA did not include a reliability safety valve in the proposed federal plan rules because the

federal plans are trading ready. However, the ability of a particular electric generating unit to

obtain allowances or credits at all times and in all circumstances is dependent upon broadly

available and liquid carbon trading markets. In the event a reliability issue arises, the ability to

manage the situation should not hinge upon whether allowances or credits are available. If

allowances or credits are not available, the electric generating unit should be able to use the

reliability safety valve. Just as the reliability safety valve is prudent in the case of State plans,

it is likewise prudent for inclusion in the final federal plan rules.


Establishment of a process to consider reliability when proposing to issue a federal plan and

authorization of a reliability safety valve would enable the federal plan rules to have the same

reliability safeguards as State plans. MISO advises EPA to make these additions to the final

federal plan rules as reasonable electric system reliability measures.
