Wind-solar-storage transformer solutions

Ningxia Muhe Energy Storage Project

The Ningxia Muhe energy storage project has a storage capacity of 200MW/400MWh. On December 13, 2022, the Ningxia Muhe 200MW/400MWh energy storage station was successfully connected to the grid, ushering in a new stage for building Ningxia's low-carbon renewable power system. The station set three industry "firsts" in one stroke: earliest grid connection, largest scale, and most advanced technology. The project uses CEEG SC(B)-2300/36.5kV [epoxy resin cast dry-type transformer](scb-series-dry-type-power-transformer)s.

CNNC Tancheng Energy Storage Station, Shandong

On December 29, 2022, the 101MW/204MWh Tancheng energy storage station project of Shandong CNNC was successfully connected to the grid. The project is among Shandong's first batch of 2022 provincial key infrastructure projects and provincial energy storage demonstration projects, and is CNNC's first grid-side large-scale energy storage project connected to the grid in Shandong. The project uses the CEEG SC(B)-3750/37kV epoxy-cast dry-type transformer.

South Africa Project

South Africa is Africa's second-largest economy, with well-developed energy and transportation sectors and world-leading technologies such as deep-shaft mining. The South African project adopted CEEG solar-storage all-in-one systems, which integrate multiple advanced components for high safety, reducing costs and improving efficiency. The products are now widely used in scenarios such as PV with storage, wind with storage, thermal power with storage, and commercial and industrial storage.

Xinjiang Altay Energy Storage Project

CEEG won the bid for the 100MW/400MWh energy storage project in Altay, Xinjiang, and efficiently completed the delivery of its transformer products. The project's commissioning marks a new stage in building a low-carbon renewable power system in the Altay region. This energy storage station can effectively improve the stability of power output without adding pressure on grid peak regulation, participate deeply in integrated source-grid-load-storage operation, and achieve efficient, clean energy utilization.

Tibet Zanda Energy Storage Project

The Zanda 20MW photovoltaic energy storage project in Tibet is a guaranteed photovoltaic project located in Tuolin Town, Zanda County, Ngari Prefecture, where the terrain of the site area is highly undulating and the elevation ranges from 3,600m to 3,800m. The site lies about 4.8 km southeast of the county seat, with County Road 705 passing to its north, offering convenient transportation and favorable conditions for production and daily life. The installed capacity is 20MW, configured with energy storage facilities of 20% for 5 hours (4MW/20MWh), and a new 35kV switching station will be built. The project selected the CEEG SC(B)-2300/36.5kV [epoxy cast-resin dry-type transformer](scb-series-dry-type-power-transformer).
