As winter approaches, understanding key trends in the power markets is crucial for traders, analysts and asset owners. This blog expands on the Winter 2024 Power Market Outlook webinar, focusing on the Midcontinent Independent System Operator (MISO), PJM Interconnection (PJM) and Southwest Power Pool (SPP) regions. Below, we’ll explore weather forecasts, renewable energy developments, transmission updates and price predictions to provide a comprehensive analysis to guide you this winter season.
With a 15-year head start in renewables and grid intelligence, real-time grid optimization to the node and unparalleled expertise in load forecasting that has outperformed the ISO forecasts, Enverus Power and Renewables is uniquely positioned to support all power insight needs and data driven decision making. More than 6,000 businesses, including 1,000+ in electric power markets, rely on our solutions daily.
MISO: Renewable Growth Meets Congestion Challenges
Weather Outlook and Load Predictions
MISO’s winter forecast aligns with ENSO-neutral to weak La Niña conditions, predicting milder-than-average temperatures with short but intense cold snaps. December’s cold risk, modeled after 2016 analogs, includes extreme lows such as -1°F in Indianapolis. However, January and February are anticipated to remain warmer overall, reducing heating demand
Renewable Energy and Infrastructure Updates
MISO is experiencing significant renewable energy additions, particularly solar projects like the Double Black Diamond Solar Project, an 800 MW facility expected online by January. The project will enhance grid reliability but could create localized congestion near Springfield, Illinois.
Price and Heat Rate Forecasts
Much of the congestion risk for January is front loaded with transmission work early in the month increasing the risk for MAPL-CHRY, which would push INDY HUB heat rates near our bullish scenarios. Enverus power solutions help users understand the grid and manage your load and power plants to best mitigate risks related to congestion, pricing and reliability.
Roughly 1GW of generator outages expected in February 2025 in MISO weakening the supply stack.
Price forecasts for MISO suggest elevated heat rates due to congestion risks and cold snap potential. December’s base heat rate of 14.5 aligns with market expectations, while January and February see higher forecasts at 14.9 and 15.2 due to planned generator outages and regional transmission constraints

PJM: Balancing Stability With Scarcity Pricing Risks
Weather Trends and Load Impacts
PJM is projected to experience a generally mild winter, punctuated by brief cold events. December’s cold anomalies, reflecting 2016 patterns, could lead to significant demand spikes. January and February continue the mild trend but with occasional risks of colder weather
A number of renewable projects are slated to come online within the first half of 2025. Enverus project coverage is the most comprehensive in the market, spanning more than 25,000 solar projects, 15,500 wind projects, 23,000 traditional projects and 7,000 storage projects. Enverus research team continuously monitoring the interconnection queue for project timelines.
Transmission and Capacity Developments
Transmission constraints remain a significant factor in PJM. Outages on key lines, such as the Millwood-Sakron 500 kV, are expected to drive bullish congestion in December and January. Additionally, Dominion’s Fredericksburg-to-Possum Point rebuild, though not yet impacting winter 2024, underscores the long-term need for infrastructure upgrades
Market Trends and Pricing
PJM’s December heat rate forecast of 16.2 indicates congestion-driven price risks, particularly around the WHUB. Risks extend into January and February, with heat rates climbing further due to transmission outages and localized cold snaps
SPP: Integrating Wind and Alleviating Congestion
Weather Forecast and Load Expectations
SPP anticipates warmer-than-average winter conditions, with analog years like 2017 highlighting short but intense cold snaps in January. The overall milder weather should reduce system-wide load, but these sharp events pose risks to grid reliability especially if they include ice storms reduce wind generation
A number of renewable projects are slated to come online within the first half of 2025. Enverus project coverage is the most comprehensive in the market, spanning more than 25,000 solar projects, 15,500 wind projects, 23,000 traditional projects and 7,000 storage projects. Enverus research team continuously monitoring the interconnection queue for project timelines.
Renewable Energy and Transmission Projects
SPP is at the forefront of wind energy expansion, with projects such as:
- Gruver Wind (160 MW in Oklahoma)
- Oliver County Wind (200 MW in North Dakota)
Additionally, transmission projects like the Norman Hills Transmission Expansion aim to address congestion in key areas around Oklahoma City.
Price and Heat Rate Trends
SPP’s pricing outlook reflects moderate risks, with December heat rates forecast at 16.7, aligning closely with market expectations. January and February rates are slightly elevated at 16.5, driven by wind integration challenges and potential transmission congestion
