By Type Insights

The day-ahead trading segment is estimated to witness significant growth during the forecast period.

Day-ahead trading refers to the voluntary, financially binding forward electricity trading that occurs in exchanges such as the European Power Exchange (EPEX Spot) and Energy Exchange Austria (EXAA), as well as through bilateral contracts. This process involves sellers and buyers agreeing on the required volume of electricity for the next day, resulting in a schedule for everyday intervals. However, this schedule is subject to network security constraints and adjustments for real-time conditions and actual electricity supply and demand. Market operators, including ISOs and RTOs, oversee these markets and ensure grid reliability through balancing and ancillary services. Traders, including utilities, energy providers, and professional and institutional traders, participate in these markets to manage price risk, hedge against price volatility, and optimize profitability.

Key factors influencing electricity prices include weather conditions, fuel prices, availability, construction costs, and physical factors. Renewable energy sources, such as wind and solar power, also play a growing role in these markets, with the use of Renewable Energy Certificates and net metering providing consumer protection and incentives for homeowners and sustainable homes. Electricity trading encompasses power generators, power suppliers, consumers, and system operators, with contracts, generation data, and power station dispatch governed by market rules and regulations.

Virtual Power Plant Forecasting Market Outlook

According to our latest research, the Global Virtual Power Plant Forecasting market size was valued at $1.8 billion in 2024 and is projected to reach $8.9 billion by 2033, expanding at a CAGR of 19.7% during 2024–2033. One of the primary factors fueling this robust growth is the accelerating integration of distributed energy resources (DERs) and renewable power assets into modern grids, necessitating advanced forecasting solutions for efficient virtual power plant (VPP) management. The rising complexity of energy systems, driven by the rapid adoption of solar, wind, and battery storage, has made accurate forecasting indispensable for grid stability, market participation, and maximizing asset value. As utilities and energy providers increasingly leverage VPPs to balance supply and demand in real time, the demand for sophisticated forecasting platforms—powered by artificial intelligence, machine learning, and hybrid modeling techniques—continues to surge globally.

Regional Outlook

North America holds the largest share of the Virtual Power Plant Forecasting market, accounting for approximately 38% of global revenue in 2024. This dominance is attributed to the region’s mature energy markets, advanced grid infrastructure, and proactive policy frameworks supporting renewable integration and grid modernization. The United States, in particular, has witnessed substantial investments in smart grid technologies and the proliferation of distributed energy resources, driving the adoption of sophisticated VPP forecasting solutions. Regulatory mandates, such as FERC Order 2222, have further catalyzed market growth by enabling DERs to participate in wholesale energy markets, thus amplifying the need for accurate load, price, and renewable forecasting. Major technology vendors and utilities in North America are collaborating to deploy advanced forecasting platforms, ensuring the region remains at the forefront of innovation and deployment in this sector.

Asia Pacific is emerging as the fastest-growing region in the Virtual Power Plant Forecasting market, with a projected CAGR exceeding 23% from 2024 to 2033. The region’s rapid urbanization, soaring electricity demand, and ambitious renewable energy targets are driving large-scale investments in smart grid and VPP technologies. Countries like China, Japan, South Korea, and India are actively deploying distributed solar, wind, and energy storage assets, creating a fertile ground for advanced forecasting solutions. Government-led initiatives, such as China’s "New Infrastructure" policy and Japan’s push for a decarbonized society, are incentivizing the adoption of digital energy management tools. Additionally, the increasing participation of technology startups and global solution providers in the region is fostering innovation, localization, and cost-effective deployment of VPP forecasting platforms.

In emerging economies across Latin America, the Middle East, and Africa, the adoption of Virtual Power Plant Forecasting solutions is gaining momentum but faces unique challenges.
