Taipei, June 10, 2025 – MacKay Memorial Hospital, a leading institution in Taiwan’s healthcare sector, is taking a significant step toward its sustainability goals by joining Enel X Taiwan’s Virtual Power Plant (VPP) - the largest Demand Response VPP in the country. Through this collaboration, MacKay Hospital will contribute its flexible energy demand to the Taiwan Power Company’s Energy Trading Platform, supporting grid stability and the broader energy transition. Enabled by Enel X’s advanced energy solutions, the partnership will help the hospital optimize energy efficiency, meet national energy-saving policies, and further its strong commitment to ESG and sustainability leadership.
According to the ‘2024 Non-Production Sector Energy Audit Annual Report’, hospitals accounted for the highest proportion of energy consumption among Taiwan’s non-production sectors in 2023, reaching 15.97%1. Given hospitals’ high emphasis on electricity safety and their meticulous power planning to ensure the stability and continuity of medical services, how to balance safety with sustainability has become a crucial issue that major medical institutions cannot ignore.
Roger Chen, Head of Enel X Taiwan, explained, “Participating in Demand Response Ancillary Services in the Energy Trading Platform via a Virtual Power Plant is an extremely suitable energy management option for hospitals. With flexible participation hours, the program is best suited to institutions that operate 24-7. When responding to grid dispatch events, the actual reduction in electricity consumption can be recognized as measurable energy-saving performance. In addition, the revenue generated from participating in the electricity market can help offset rising electricity costs and be reinvested into other sustainability initiatives.”
In the future, during times of grid stress, MacKay Hospital will be able to temporarily reduce energy use from non-essential equipment within ten minutes. Enel X’s Virtual Power Plant will aggregate this flexibility alongside other commercial and industrial Demand Response resources, delivering it to the grid as a single, coordinated resource. This helps to enhance grid resilience and support a stable, reliable power supply .
Chang Wen-han, Superintendent of MacKay Memorial Hospital, stated, “MacKay Hospital has always prioritized social responsibility and sustainable development. Our goal is not only to provide high quality medical care, but also to actively support the transition to net-zero and to set the standard for other medical centers. As summer brings peak electricity demand, hospitals must consider more effective energy-saving strategies and promote the renewable energy development in order to demonstrate their commitment to energy conservation.”
Roger Chen, Head of Enel X Taiwan, said, “We are delighted to have MacKay Hospital join our ranks. As power supply shifts from centralized to distributed generation, every energy user plays an important role in stabilizing the grid and promoting the development of renewable energy. With the right Virtual Power Plant, even hospitals – where power reliability is critical – can safely participate in the energy market without compromising operations. We encourage all major energy users to unlock the value of their existing assets, take advantage of opportunities in the energy market, and ”contribute to a more resilient and sustainable energy future.”
Enel X is currently the largest power aggregator of Demand Response Resources in the Energy Trading Platform, with over 200MW of aggregated capacity - equivalent to the electricity load of 80,000 households. Looking ahead, Enel X plans to continue expanding this capacity and, in line with market trends, support users in participating in the energy market through behind-the-meter energy storage systems.
