Jinko ESS, the energy storage arm of JinkoSolar Co., Ltd., has successfully supplied 722MWh of energy storage equipment for a major renewable energy development in India. The project incorporates 144 units of the company's SunTera G2 liquid-cooled energy storage systems, which are designed to support large-scale renewable energy integration, enhance grid reliability, facilitate clean energy distribution, and assist with peak demand management. Beyond supplying equipment, Jinko ESS offers comprehensive services including system integration, project execution, and long-term operational support tailored to various energy storage applications.

As renewable energy projects expand and a greater share of power generation is connected to national grids, energy storage has emerged as a crucial component for maintaining grid stability and optimizing asset performance. Utility-scale renewable energy facilities require storage solutions capable of meeting stringent standards for safety, environmental resilience, project delivery, and ongoing service support.

The Indian project presents several operational challenges, including extreme heat, elevated humidity levels, dusty conditions, intense solar exposure, and logistical complexities associated with long-distance transportation. These demanding conditions necessitate robust engineering, advanced thermal management, high protection standards, and dependable on-site service capabilities. The successful deployment of the 722MWh system highlights Jinko ESS's expertise in delivering large-scale energy storage solutions in challenging environments.

To address these requirements, the SunTera G2 system utilizes advanced liquid-cooling technology that maintains battery cell temperature variations within 2.5°C, improving system efficiency, consistency, and long-term operational reliability. The solution is engineered to perform in temperatures of up to 55°C and humidity levels reaching 99%. Additional features such as an IP55-rated enclosure, corrosion-resistant design, multilayer safety mechanisms, and intelligent thermal controls ensure dependable and secure operation for large renewable energy installations.

While equipment supply marks an important milestone, sustained performance throughout the system's lifecycle remains essential for maximizing customer value. Drawing on its expertise in battery cells, PACK manufacturing, system integration, and global project execution, Jinko ESS provides end-to-end support that includes system design, product deployment, field services, and long-term operations and maintenance partnerships. The company also offers an AI-enabled Energy Management System (EMS) that delivers real-time monitoring, operational analysis, load forecasting, and charge-discharge optimization, helping customers improve renewable energy utilization, strengthen grid responsiveness, and enhance asset returns.

According to Anita Li, Vice President of Jinko ESS, the growing scale of renewable energy projects is driving increased expectations for energy storage solutions. She noted that energy storage systems play a vital role not only in capacity management but also in ensuring project safety, grid dispatch efficiency, and long-term economic performance. Li described the successful delivery of the 722MWh project as another significant milestone for the company in handling complex utility-scale applications and reaffirmed Jinko ESS's commitment to supporting customers through reliable technology, effective project delivery, and ongoing service support.

Looking ahead, Jinko ESS intends to continue supporting large-scale energy storage developments worldwide through its integrated approach encompassing advanced products, system integration expertise, project management capabilities, and long-term service offerings. The company aims to contribute to a more resilient, adaptable, and sustainable global energy infrastructure as the transition to clean energy accelerates.

Duke Energy Florida has successfully brought all 10 of its Clean Energy Connection solar sites online, fulfilling its commitment outlined in a 2020 filing with the Florida Public Service Commission. This initiative has contributed nearly 750 megawatts of solar power to Florida’s energy grid between 2022 and 2024.

“Expanding solar energy is essential for a modern, diverse, and resilient power grid,” said Melissa Seixas, Duke Energy Florida’s state president. “I’m excited to build on the progress we’ve made, continuing to enhance our generation fleet while ensuring we provide reliable and cost-effective energy to our customers and communities—both now and in the future.”

Each Clean Energy Connection site, with a peak capacity of 74.9 megawatts, generates enough electricity to power around 23,000 homes. Additionally, these sites collectively reduce reliance on traditional fuels by offsetting 1.2 million cubic feet of natural gas, 15,000 barrels of fuel oil, and 12,000 tons of coal annually.

Beyond clean energy production, these solar facilities have played a key role in Florida’s economic growth. Their construction generated over 1,500 temporary jobs and contributed substantial tax revenue to the counties in which they are located. The 10 sites are spread across the state, from Bay County to Hardee County:

Customers also have the opportunity to participate in the Clean Energy Connection program by subscribing to support a portion of the solar power generated by these sites. In return, they receive credits on their electricity bills—without the need to install or maintain solar panels. The monthly subscription fee, which helps cover site development and operational costs, is conveniently included in customers’ bills. More details can be found on Duke Energy’s Clean Energy Connection website.

The Clean Energy Connection program is part of Duke Energy Florida’s broader clean energy strategy, which now includes over 25 solar sites generating nearly 1,500 megawatts of emission-free power. Looking ahead, the company plans to add 12 new solar facilities between 2025 and 2027, contributing another 900 megawatts to the grid. Over the next decade, Duke Energy Florida aims to expand its utility-scale solar capacity by at least 450 megawatts annually.
