Industry Report: Forecasting Services for Wind and Solar Farms

As variable renewable energy sources account for an expanding share of global electricity generation, the ability to predict wind and solar output with precision has emerged as critical infrastructure.

Forecasting services for wind and solar farms translate meteorological data and asset characteristics into time-sequenced generation estimates that underpin real-time grid operations, market bidding strategies, risk management frameworks, and long-term project finance decisions.

These services operate at the intersection of advanced meteorology, power-system operations, and energy market design—delivering products ranging from ultra-short nowcasts to multi-day schedules, probabilistic risk outputs, and ramp alerts.

Understanding the structure, dynamics, and trajectory of this sector is essential for stakeholders seeking to navigate the complexities of renewable energy integration. 

Market Fundamentals and Growth Trajectory

The global market for wind and solar forecasting services reached approximately USD 5.5 billion in 2024 and is projected to expand at a compound annual growth rate of 12 percent through 2030. This translates to an estimated market size of USD 6.16 billion in 2025, USD 6.93 billion in 2026, and USD 7.80 billion in 2027. This robust growth reflects the accelerating deployment of wind and solar capacity worldwide, the intensification of grid modernization initiatives, and the increasing sophistication of electricity markets that reward accurate, uncertainty-aware forecasting.

Regional patterns reveal distinct dynamics. North America and Europe represent the most mature markets, characterized by advanced grid infrastructures, well-developed market mechanisms, and high data availability. The Asia-Pacific region, meanwhile, is experiencing the fastest expansion, driven by large-scale renewable installations and the ongoing modernization of regulatory systems. These geographic variations underscore the importance of aligning product offerings with local market structures, regulatory frameworks, and customer needs.

Several structural drivers sustain demand across regions:

  1. Rising penetration of intermittent renewables elevates the economic and reliability costs of forecast error, creating sustained demand for high-quality products across all time horizons.
  2. Regulatory and market design evolution increasingly emphasizes forecast quality, transparency, and performance accountability—particularly in the form of probabilistic outputs, ramp alerts, and demonstrated forecast skill.
  3. Technological advances in meteorological modeling, satellite and sky imagery, and machine learning post-processing are enabling material improvements in accuracy, especially at ultra-short and short horizons where real-time operational decisions depend on predictive fidelity.

Customer Segmentation and Value Delivery

The forecasting services industry is best understood through two primary segmentation dimensions: customer type and forecast horizon. Each customer segment faces distinct decision cycles, procurement complexities, and economic drivers, which in turn shape product specifications, service-level expectations, and pricing models.

System operators and independent system operators prioritize aggregated, probabilistic forecasts that support balancing, reliability, and reserve provisioning decisions. Their procurement processes are characterized by high integration requirements, stringent service-level agreements, and formal performance auditing. Market participants and traders, by contrast, require deterministic schedules with probabilistic overlays to optimize market bids and hedging strategies, with emphasis on latency, update frequency, and API reliability.

Asset owners and plant operators seek site-level forecasts with ramp detection capabilities to minimize imbalance charges and optimize maintenance windows.

Developers, financiers, and lenders demand statistically robust, long-term yield distributions and probabilistic risk metrics to underwrite project finance and manage portfolio exposure.

Distribution utilities and distributed energy resource aggregators need granular, scalable forecasts to manage increasingly complex, geographically dispersed asset portfolios.

Forecast horizon—ranging from ultra-short nowcasts (0–2 hours) to seasonal and long-term projections (weeks to years)—determines the dominant input data, modeling methodologies, update frequencies, and decision-making contexts. This dual segmentation framework enables precise mapping of product features to contractual arrangements and technology choices, reinforcing the sector’s emphasis on aligning outputs with the specific penalties, incentives, and operational workflows faced by each customer type.

Competitive Dynamics and Differentiation

The competitive landscape is moderately consolidated, with a small set of global data and forecasting providers—such as Solcast, Vaisala, The Weather Company (IBM), DTN, Meteomatics, Meteoblue, and DNV—coexisting with a broader set of niche and regional specialists. These incumbents benefit from extensive observational networks, advanced numerical weather prediction capabilities, and deep integration with client operational stacks.

Competitive differentiation hinges on several factors: data quality, model transparency, horizon-specific product design, and the ability to deliver consistent, validated performance under stringent service-level agreements.

The sector exhibits high barriers to entry, driven by the capital intensity of data acquisition, compute infrastructure, and model development, as well as the need to build trust through performance benchmarking and regulatory compliance. Switching costs are substantial, as forecast outputs must integrate seamlessly with energy management systems, supervisory control and data acquisition platforms, trading systems, and distributed energy resource management platforms.

Trends Shaping the Future of Forecasting

Five key trends are reshaping the industry:

  1. Probabilistic forecasting is becoming the standard across horizons, with ensemble outputs, quantiles, and probabilistic performance metrics replacing or augmenting single-point forecasts. This shift enables risk-aware scheduling, more accurate reserve provisioning, and improved hedging and pricing decisions.
  2. Ultra-short nowcasting is maturing rapidly, leveraging sky imagery, satellite data, and rapid data fusion to deliver 0–2 hour forecasts with high temporal resolution.
  3. Hybrid and modular delivery models are emerging, blending centralized and decentralized approaches to serve diverse customer needs and asset portfolios.
  4. Performance validation, bias correction, and continuous benchmarking are becoming core offerings, driving transparency and accountability in forecast quality.
  5. Regulatory evolution toward standardized forecast quality metrics, transparency, and traceability is shaping product specifications, procurement rules, and interoperability standards.

Conclusion: Building Trust Through Transparency and Performance

Forecasting services for wind and solar farms are fundamental enablers of the energy transition, translating complex meteorological and asset data into decision-relevant, uncertainty-aware products that reduce operational risk, optimize market participation, and support long-term investment confidence.

As the electricity system transitions toward higher shares of variable renewable generation, demand for sophisticated, reliable, and transparent forecasting services will intensify. Success in this environment will depend on the ability to deliver superior performance, maintain data and model discipline, and adapt to evolving market and regulatory requirements. For stakeholders across the value chain, the imperative is clear: invest in quality, transparency, and integration to build enduring trust and capture sustainable value.
