Renewable Natural Gas Study Workgroup
Public Act 87 of 2021 directed the Michigan Public Service Commission to conduct a study into the potential for renewable natural gas development in the state. In part, PA 87 directs the Commission to identify and engage interested stakeholders in the development of the study. In response, on December 9, 2021, the Commission issued an order in Case No. U-21170 establishing the Renewable Natural Gas Study workgroup.
The Renewable Natural Gas Study will:
- Identify existing and potential sources of renewable natural gas (RNG) in Michigan and estimate the energy content and greenhouse gas abatement potential of these sources.
- Estimate the cost per unit of heat and the potential greenhouse gas emission reduction per unit of heat should potential RNG sources be used to the greatest practical extent.
- Compare the estimated per-unit cost savings of greenhouse gas emission reductions estimated for RNG sources to the estimated likely per-unit cost savings from the use of other carbon abatement technologies, including hydrogen blending, building electrification, and similar technologies.
- Estimate the RNG production potential by applicable feedstock sources in Michigan.
- Identify barriers to developing and utilizing RNG in Michigan.
In accordance with PA 87, the Commission will issue a report to the legislature by September 30, 2022. The Commission has enlisted the help of ICF to facilitate the exploration of RNG sources, costs, and estimated greenhouse gas emission reductions, with opportunities for feedback from stakeholders, and to assist in delivery of the study requested in PA 87.
Documents and Resources
ACTIONS TO DATE
- The RNG Study draft outline was posted and distributed to stakeholders in December 2021.
- The first stakeholder meeting was held on January 10, 2022. ICF reviewed the scope and timeline of the study, and addressed questions and comments from stakeholders. Comments from stakeholders made during the stakeholder meeting can be found here.
- Additional stakeholder comments were provided to MPSC by the following entities:
- In March 2022, MPSC sought input from stakeholders concerning existing greenhouse gas (GHG) emission reduction studies, especially those that quantify GHG abatement costs of comparable technologies. A list of resources received can be found here and will be considered for incorporation into the draft report.
- A second stakeholder meeting was held on April 20, 2022, where ICF reviewed the inputs, assumptions, and methodologies being used in the RNG Study, and stakeholders had an opportunity to weigh in on those inputs, assumptions, and methodologies. Stakeholders also participated in discussions regarding competing uses of RNG feedstocks and alternatives to RNG. Responses to stakeholder questions asked during the April 20 meeting can be found below, along with comments received after the meeting.
- Responses to Stakeholder Question from 4-20-2022 RNG Study Stakeholder Meeting
- Michigan Food for All and the Earth Project
- Michigan Farm Bureau
- Upper Michigan Energy Resources Corp and Michigan Gas Utilities
- Michigan Food for All and the Earth Project, Progress Michigan, Michigan Organic Food and Farm Alliance, Michigan Environmental Justice Coalition, Natural Resources Defense Council, and Sierra Club
- Public Comment
- Stakeholder feedback on the draft study outline and other topics have been considered and ICF will continue to draft the RNG Study report in the upcoming months.
- A complete draft report will be posted for review in advance of a third stakeholder meeting anticipated this summer. Details will be announced closer to that time.
