The investment from Acario, revealed on July 16, 2025, reflects confidence in Amperon’s AI-powered forecasting technology, which integrates machine learning, physics-based modeling, and weather ensemble features. Since its 2024 expansion into markets like the UK, France, Germany, and Spain, Amperon supports customers across 15 European countries, the US, Canada, and Australia. “Bringing Tokyo Gas and Acario on board as investors is a meaningful step in Amperon’s global trajectory,” said Sean Kelly, CEO and Co-Founder of Amperon.
Founded in 2018, Amperon delivers demand, renewable generation, and price forecasts, leveraging real-time weather, consumption, and market data. Its platform outperforms traditional providers, serving energy retailers, utilities, and independent power producers like Ørsted, Axpo, AES, and Rhythm Energy. The company’s predictive analytics enhance grid reliability, optimize asset performance, and manage financial risk in volatile energy markets, supporting the global energy transition.
Tokyo Gas, Japan’s largest gas utility, serves over 3.8 million electricity customers and aims for net-zero CO2 by 2050 under its “Compass2030” vision. Acario, its Silicon Valley-based innovation arm founded in 2017, invests in energy, sustainability, and digital transformation. “Amperon’s AI-powered forecasting technology is unique in its accuracy and scalability,” said Kenji Maeda, CEO of Acario, emphasizing its role in enabling smarter energy trading and grid stability.
Amperon’s technology addresses the complexities of modern energy markets, driven by renewable integration and extreme weather events. Its 10% accuracy improvement over six months, noted in March 2025, underscores its leadership. The investment follows a $20 million Series B round in 2023 led by Energize Capital and a National Grid Partners investment in March 2025, bringing total funding to over $30 million. These partnerships align with global decarbonization goals, though some question the scalability of AI-driven forecasting in less data-rich markets.
Amperon’s collaboration with Acario strengthens its position as a key player in energy forecasting, driving innovation and resilience in the global energy transition.
