In the early days of summer, good news keeps pouring in. Recently, three new energy projects of Kunming Institute successfully achieved grid-connected power generation in succession. These three projects, concentrated grid connections, are another important practical achievement of Kunming Institute in actively serving the national "dual carbon" strategic goal and deeply cultivating the green energy field. They not only demonstrate its outstanding capability in new energy project services, but also contribute solid "Power Construction strength" to promoting local green and low-carbon economic and social development and the optimization and upgrading of the energy structure.

The 100MW photovoltaic power generation project (Phase II) EPC general contracting project in Yinggehai, Ledong County, Hainan successfully achieved grid-connected power generation

The project is invested and constructed by Hainan Jiaokong Energy Co., Ltd., and was won and undertaken by a consortium composed of Kunming Institute and the Third Bureau of Hydropower. Kunming Institute (lead party) undertook the survey and design work, with the Municipal Engineering Institute performing the contract, and the Third Bureau of Hydropower (member party) responsible for material and equipment procurement, construction, and other work.

The project is located near the Yinggehai Salt Field in Ledong Li Autonomous County, Hainan Province. A total of 31 photovoltaic arrays were built (AC-side capacity 100MW, DC-side capacity 121.4906MWp), and one new 220kV booster station (Yangfan Photovoltaic Station) was constructed. The booster station has one new 220kV (11.9km) line connected to the 220kV Xin'an Station. After completion, the average annual power generation will be 170.3278 million kW·h.

The 100MW/200MWh centralized shared new-type energy storage EPC general contracting project in Baishui Xiaotang, Zhanyi District was put into operation and connected to the grid

As a key centralized shared energy storage project in Yunnan Province, the project has an installed scale of 100MW/200MWh and is equipped with a lithium iron phosphate battery system. It is divided into four 25MW/50MWh energy storage subsystems, connected to the Qujing Power Plant booster station via four 35kV lines, and then connected to the power grid via a 220kV line. Together with the Qujing thermal power plant and surrounding wind power and photovoltaic projects, it forms a "wind-solar-thermal-storage" joint regulation network, providing a core support point for the "source-grid-load-storage integration" in eastern Yunnan. After the project is put into operation, it can help the Qujing Power Plant increase revenue by more than ten million yuan annually, increase local tax revenue, drive the implementation of industrial chains such as energy storage equipment manufacturing and operation and maintenance services, and inject green momentum into rural revitalization.

The completion of the project plays a positive role in promoting new energy consumption in the Qujing area and enhancing the operational safety of the regional power grid. It is of milestone significance for promoting high-quality development, forming a development pattern of joint operation of new energy and thermal power, and building the "Eastern Yunnan Wind-Solar-Thermal-Storage Integrated Clean Energy Base."

The PC general contracting project of Section A of the plant area works of the China Resources Power Tanghe County 200MW Photovoltaic Project achieved full-capacity grid-connected power generation

The project is located within Huyang Town, Tanghe County, Nanyang City, Henan Province. Kunming Institute undertook the PC general contracting of Section A of the plant area works, adopting string-type grid connection, with a total of 31 sub-arrays. The rated capacity of the photovoltaic plant area is 100.8MW, the installed capacity is 121.35MW, and the construction period is 303 days. The project achieved "0530 grid connection" on schedule, demonstrating Kunming Institute's outstanding professional capability, rigorous and pragmatic work style, and honest and trustworthy spirit of contract.
