Chinese photovoltaic module manufacturer JinkoSolar Holding Co., Ltd. (JinkoSolar) has announced the commissioning of three energy storage installations with a total capacity of 21.6 megawatt-hours (MWh) in the U.S. state of Massachusetts, implemented on behalf of the company Distributed Energy Infrastructure (DEI). This delivery is part of the state’s Solar Massachusetts Renewable Target (SMART) programme, designed to encourage the integration and efficiency of solar resources into the local power grid.
Technical characteristics of the delivered systems
The three installations implemented by DEI rely on hybrid technologies combining both direct current (DC) and alternating current (AC) configurations. This technical approach enables better adaptation of equipment to grid constraints and offers optimised management of local photovoltaic power production.
The installations are designed to directly strengthen operational efficiency and solar integration capability within the Massachusetts grid, while offering additional services aimed at stabilising local electricity supply. They thus allow dynamic management of electrical flows and better adaptation to solar energy variability.
Contribution from JinkoSolar’s American technical teams
The implementation of the systems provided by JinkoSolar was supported by extensive technical assistance from its American subsidiary, JinkoSolar (U.S.) Inc. The latter ensured full coordination of aspects related to engineering, design, and technical integration of storage systems with Power Conditioning Systems (PCS) and Energy Management System (EMS) platforms.
This close collaboration between the American teams of JinkoSolar and DEI allowed the rapid and smooth commissioning of the installations. The local technical expertise of the Chinese supplier facilitated the swift integration of systems into the existing grid and proactive management of technical constraints encountered in the field.
Integrated project management by DEI
Distributed Energy Infrastructure managed these three installations from end to end, including planning, equipment procurement, installation work, and final commissioning. DEI highlighted its integrated model as a way to reduce execution risks, ensure adherence to deadlines, and guarantee technical consistency between different project phases.
According to Sean Harrington, CEO and founder of DEI, “these projects illustrate our commitment to delivering resilient energy solutions to local communities, in close partnership with experienced technical suppliers such as JinkoSolar.”
Jeff Juger, Deputy General Manager and Head of ESS (Energy Storage Systems) at JinkoSolar (U.S.) Inc., emphasised that “working directly with DEI’s American team effectively streamlined technical integration and accelerated the commissioning of the supplied systems.”
