Genex Power

Genex Power is an Australian electricity-generation and renewable-energy development company whose portfolio combines utility-scale solar generation with dispatchable and short-duration energy storage. Its principal development platform is the Kidston Renewable Energy Hub in Queensland, where the company has developed a solar project and has been advancing a pumped-hydro storage facility that would reuse infrastructure associated with the abandoned Kidston gold mine. This approach links new renewable generation with storage capacity intended to support electricity-system flexibility. The company owns the Kidston Solar Project, which has generated up to 50 megawatts of electricity since 2017, and the Jemalong Solar Project. Genex has also operated the Bouldercombe Battery, a 50 MW/100 MWh grid-scale battery near Rockhampton. In addition to these operating and developing assets, it has considered expanding the solar facilities and adding wind generation around the Bouldercombe area, as well as developing a combined solar-and-battery project at Bulli Creek in Queensland. Genex’s business model is centered on the development, construction, ownership and operation of large renewable-energy and storage assets rather than on a consumer-facing electricity-retail brand. Its projects address two complementary requirements of Australia’s electricity transition: increasing low-emissions generation and providing storage or flexibility when solar and wind output varies. The reuse of a former mining site at Kidston is a distinctive part of the company’s project strategy, potentially reducing the need to establish an entirely new storage location while giving a former resource site a new energy-related role. The company was publicly traded under the ticker GNX. In 2024, Japanese power company J-Power completed the purchase of Genex Power in a transaction reported as being valued at A$228 million. This transaction changed the ownership context of the business, although the available reference material does not establish the company’s post-transaction legal status, whether the brand continued as a separately listed entity, or the precise timing of any delisting. Genex Power is therefore best understood as an Australian renewable-generation and energy-storage platform associated with the Kidston, Jemalong, Bouldercombe and proposed Bulli Creek projects.

Genex Power developed as an Australian electricity-generation company with a focus on renewable generation and energy storage. Rather than concentrating on conventional utility assets or retail electricity supply, its project portfolio has been built around the combination of solar generation and storage technologies. This model reflects the operational challenge created by variable renewable generation: solar projects can produce substantial electricity during daylight hours, while storage can shift energy availability and provide additional flexibility to the grid. The company’s central development concept is the Kidston Renewable Energy Hub in Queensland. Genex owns the Kidston Solar Project, which has generated up to 50 MW since 2017. The solar project established an operating renewable-generation base at a site with a broader energy-development ambition. Genex has been developing the associated Kidston Pumped Hydro storage project, using the former Kidston gold mine. Reusing an abandoned mining site for pumped storage is a defining feature of the project because it connects the region’s industrial history with a new electricity-storage application. The company has also considered adding further renewable generation, including a wind farm, to create a more integrated clean-energy hub. Beyond Kidston, Genex owns the Jemalong Solar Project and operates the Bouldercombe Battery near Rockhampton. The Bouldercombe facility has a stated capacity of 50 MW and energy-storage capacity of 100 MWh, positioning it as a grid-scale battery asset rather than a behind-the-meter or residential product. Genex has considered expanding solar generation and adding wind generation in the Bouldercombe area. It has also proposed a solar farm and battery at Bulli Creek in Queensland, extending the company’s development interests to another integrated renewable-and-storage location. These assets and proposals illustrate Genex Power’s strategic emphasis on utility-scale infrastructure. The company’s role is to develop, construct, own and operate generation and storage projects capable of participating in Australia’s electricity market. Its portfolio spans operating solar and battery assets as well as longer-term projects that depend on development, financing, construction and regulatory progress. The available reference material does not provide a complete chronology of project approvals, financing arrangements, construction contracts or commercial offtake agreements, so those details are not included here. Genex Power was publicly traded under the GNX ticker. In 2024, Japanese power company J-Power completed the acquisition of the Australian company in a deal reported to be valued at A$228 million. The transaction marked a significant ownership change for Genex and placed its renewable-generation and storage platform under an international power-sector owner. The available material does not establish the precise post-acquisition corporate structure, the status of the GNX listing, or whether all projects continued under the Genex brand. Accordingly, the company’s current standalone operating and listing status remains unspecified in this dossier.
