Since 2022, MISO has provided a publicly available emissions dashboard which displays historical emissions from public Energy Information Administration (EIA) and Environmental Protection Agency (EPA) data with projected emissions, produced from member-provided information to deliver MISO's Regional Resource Assessment (RRA).
Effective August 1, 2024, MISO will post additional emissions display pages:
- near real-time, footprint-wide emissions using MISO operational fuel mix data
- marginal emissions published on a one-day lag from MISO's Market Reports

FAQ (Frequently Asked Questions):
Where do I go if I have questions on the Emissions Dashboard?
A guided "tour" of the Dashboard is available by clicking this icon . Dashboard tours are unique to each dashboard page. If the dashboard tour does not address all questions, please navigate to the MISO Help Center to submit questions via a Help Center Case. Use Case Category "Product Launch."
How can the data be accessed?
Data on each dashboard page can be customized via pulldown menus and the map graphic.
Can I download this information?
Yes. Click on this icon on each dashboard page to download selected information.
How often is this information updated?
Each page is updated on a different schedule.
- Historical and Projected Emissions: pages are updated annually as new information becomes available.
- Near Real-Time Emissions: page is updated every 5-minutes following publication of MISO's real-time fuel mix.
- Marginal Emissions: page is updated on a one-day lag, driven by publication timing of MISO's Fuel on the Margin report.
How is this information similar or different from one another and from EIA (Energy Information Administration) information?
- Historical Emissions: page leverages EIA and EPA information reported by utilities to the federal government.
- Near Real-Time / Marginal Emissions: pages reflect operational data from MISO's website.
- Projected Emissions: page is informed by member-provided plans information and MISO-modeled future capacity as part of MISO Regional Resource Assessment deliverables.
Do dashboards contain confidential information?
No. All information in MISO's dashboards is publicly consumable, non-confidential and non-market sensitive. As MISO publishes additional methods of emissions estimates, publication timing and spatial/temporal granularity of data will hinge upon those criteria.
Why don't you use plant-specific information for near real-time data?
MISO is using existing operational (footprint-wide) reports to generate emissions estimates complementary to other markets & operations displays for more holistic situational awareness. This footprint-wide granularity is consistent with near real-time emissions estimates reported by other ISO's and RTO's.
Providing plant-specific information near real-time could provide insights about market behavior, which is why plant-specific historical emissions data is published on a significant lag versus real-time.
Do other ISOs and RTOs publish this information?
Yes, although the form varies, all ISOs and RTOs are either planning to publish or currently publish emissions information.
How is this different from PJM data?
Currently MISO's near real-time emissions estimates only include CO2. MISO will, however, provide generated and marginal emissions estimates on a footprint-wide basis. MISO's plan to publish locational marginal emission rates, similar to what PJM publishes, is in late 2025.
PJM provides hourly marginal emissions estimates to reflect rates of CO2, NOx and SO2 on rolling 24-hour basis, also at a footprint level. Marginal emissions are those caused by production of the last energy on the system.
- PJM also provides marginal emission rates for individual load nodes for both 5-minute and hourly bases via its Data Miner platform.
Why is MISO doing this?
MISO's objective in providing emissions estimates as a data service is to deliver incremental value to MISO members, designed to enable both reporting those emissions and providing emissions-related services to their own customers.
Why do you expect to launch additional dashboards?
MISO's plan is to launch two additional dashboard pages in 2025: Consumed Emissions in Q1 2025 and Locational Marginal Emissions in late 2025.
How can this data be used?
MISO has terms of use for information shared via its website, www.misoenergy.org. A disclaimer (bullets immediately below) will be shared within a README file that will accompany every data download of emissions estimates.

Where can I obtain detailed technical support for your methods, calculations and key assumptions?
For more detail on how emissions estimates are calculated, technical documentation will be made available within each page's dashboard "tour" or via a separate dashboard feature.
Will MISO incorporate emissions data into market pricing and dispatch rules?
Emissions data will not be incorporated into market pricing or energy dispatch at MISO.
How does MISO perceive the data quality for areas outside its footprint?
MISO has the best data for both energy operations and emissions estimates within its footprint. Data for areas outside MISO's footprint is regularly updated and used to make MISO operational decisions, but it may or may not be the same quality as MISO data.
