Spire Power Generation Forecasts deliver precision for renewable energy markets

Spire’s Power Generation Forecast is a cutting-edge solution designed to give energy traders, utilities, and grid operators a competitive edge. Leveraging the Spire High-Resolution Forecast model and advanced AI-driven modeling, this product provides hourly power generation predictions for wind and solar at a national or regional level.

AI-driven Power Generation Forecasts for wind and solar: Spire’s approach

Spire’s Power Generation Forecast integrates advanced high-resolution forecasting, state-of-the-art deep learning methodologies, and satellite-driven insights to refine power production estimates:

• Satellite-enhanced meteorology – Spire’s proprietary satellite data ensures more accurate forecasts by incorporating real-time observations of atmospheric conditions, including wind speeds at hub heights and solar radiation at the surface, critical for wind and solar power forecasting
• High-granularity inputs – Driven by Spire’s High-Resolution Forecast model, which captures fine-scale atmospheric dynamics other models miss
• Machine learning optimization – AI models continuously refine predictions using historical weather and power generation data, improving accuracy over time
• Hourly power output predictions – The model delivers MW-level power production estimates at a national or regional scale, helping traders anticipate fluctuations in renewable energy supply

Regional availability and expansion

Spire currently provides Power Generation Forecasts for France, the Netherlands, Germany, Austria, Hungary, and the United Kingdom.

Spire is also in the process of expanding coverage to ERCOT (Texas) and additional North American energy markets.

As Spire Senior Machine Learning Engineer Elliott Wobler explains: “For any new region, we need access to historical, hourly power generation data to train and validate the model. We already have initial results for ERCOT and are working on optimization strategies now.”

How energy traders and grid operators access the data

The Power Generation Forecast is available through:

• API integration – Simple, structured data feeds allow traders to integrate forecasts directly into their analytical platforms and algorithms
• Spire’s Cirrus data viewer platform – Users can visualize power generation forecasts, explore meteograms, and quickly assess trends in renewable energy output

Market validation and early adoption

Early adopters, energy trading firms, have already started integrating Spire’s forecasts into their trading workflows, providing valuable feedback that continues to refine the model’s accuracy. With frequent iteration and real-world testing, Spire is ensuring that its forecasts meet the rigorous demands of energy market professionals.

“Our clients use multiple forecasting providers, so we’ve received valuable anonymized comparisons. By leveraging Spire’s High-Resolution Forecast model, we’ve seen strong early results, especially in solar power forecasting in Europe,” Wobler explained.

Solar’s soaring growth in Europe and Texas signals a renewable shift

The European energy landscape experienced a major shift in 2024 as solar power became the fastest-growing electricity source, surpassing coal for the first time. According to Ember’s “European Electricity Review 2025,” solar generation in the EU increased by 22% year-over-year, reaching 304 TWh—enough to edge out coal, which declined to 269 TWh. This marks a significant milestone, as coal, which was the EU’s third-largest power source in 2019, has now dropped to sixth place. Solar’s expansion is widespread across Europe, with more than half of EU nations either phasing out coal entirely or reducing its share to less than 5% of their power mix, Ember reported.

During peak production hours, solar energy is approaching a new threshold in several EU countries, covering a substantial portion of electricity demand. The Netherlands and Hungary saw particularly notable growth, with over 70 days where solar generation exceeded 80% of total demand during peak hours — a significant jump from Hungary’s 10 days in 2023, according to Ember.

In the United States, Texas is experiencing a similar surge in renewable energy capacity, with solar and battery storage leading grid expansion. According to Federal Reserve Bank of Dallas research published in 2024, solar additions nearly doubled from 4,570 MW in 2023 to 9,700 MW in 2024, while battery storage capacity tripled, underscoring the rapid shift toward clean energy solutions.

This rapid acceleration of solar shines a light on the increasing need for precise, AI-driven forecasts that help energy traders, utilities, and grid operators optimize renewable energy use. Spire’s Power Generation Forecast delivers this critical insight, equipping market participants with high-resolution, satellite-powered data to anticipate fluctuations in solar output and maximize efficiency in an evolving energy landscape.

Future enhancements and expansion into key energy markets

Spire is continuously evolving its forecasting capabilities, with several enhancements to the Power Generation Forecast in the pipeline:

• Expanding coverage to key US energy markets such as ERCOT, MISO, and other key US energy markets
• Continuously improving forecast accuracy through AI model refinements and additional satellite data assimilation
• In the future, Spire aims to provide AI-driven probabilistic power generation forecasts, helping traders quantify uncertainty and refine risk management
• With customer-provided data, Spire’s system can scale to granular, site-specific forecasts, producing turbine-level or solar farm-specific forecasts
• Exploring adjacent solutions, such as outage prediction models, to further support energy market participants

By partnering with industry users, Spire aims to refine and expand this innovative solution, providing the most accurate and actionable renewable energy forecasts on the market.
