Making Renewables Dispatchable



We are StorVolt Energy, a company dedicated to helping reform  Australia's energy sector.


Australia possesses abundant minerals and an exceptional wind and solar resource. At StorVolt, we believe that harnessing these resources while minimising our carbon footprint is the key to a sustainable and prosperous future

We do this, by developing utility-scale energy storage projects, that bridge the gap between low-cost intermittent renewable energy generation and steady-state power demand. Our distributed energy storage solutions provide 5-20MW capacity, storing energy from minutes to days.

Led by three experienced executives, each with a proven track record in global energy sector projects, totalling over 20GW in renewable and conventional power brought online, StorVolt Energy combines global expertise and vision with local knowledge and presence.


Join us on our mission to help reshape Australia's energy landscape, promote sustainability, and create a cleaner, more prosperous and sustainable future. Power the change with StorVolt.

Site Identification

Storage projects have the most value in places where the grid needs support – places with high levels of renewable penetration, constrained or outdated infrastructure, or anticipated capacity deficits.
With our partners, we have the ability to screen every node in Australia for the most promising storage locations.

Project Feasibility

Once a location has been selected, we configure and optimise a project based on, inter alia, grid parameters, technical, environmental and permitting constraints and analyse it for financial viability.

The outcome of this process may be a project that has the capacity to store 5MW for 2 hours, to provide voltage and frequency support services, or 20MW for 10 hours with the main objective being energy shifting, or a combination thereof.

The project may then be configured as a stand-alone storage project near a substation, or co-located with a generating asset, sharing the grid interconnect.

Grid and Permitting

Following on from (pre-) feasibility, the project enters its development phase, including

  • Environmental and Social Impact Assessment

  • Community liaison work

  • Grid interconnect studies and agreement

  • Municipal and other permits

  • Contracting


With permits and grid interconnect agreement in place, the project is now Ready-to-Build and will go into the financing stage

Reference Projects

Sample list of projects in which the team has or had a significant or lead role


Solar PV, Caribbean

Ongoing development of a 250MW Solar PV and Energy Storage project in the Caribbean. 


Badgingarra Wind, Western Australia

Feasibility study, landholder agreements, EPBC and site approvals for the 130MW, 37 turbine, Badgingarra project.  The project generates 500-550GWh per annum, enough to supply over 100,000 WA households with 100% renewable energy. 


Kipeto Wind, Kenya

The 100MW Kipeto project is a project co-developed by a consortium comprising a local developer, the IFC/World Bank and GE Energy, with support from and participation by the local community. The project was commissioned in 2020 with a capacity factor in excess of 50%.

Wandoan IGCC, Australia

Wandoan was a proposed 400MW Integrated Gasification Combined Cycle (IGCC) project promoted by GE Energy, an Oil& Gas major, a local utility and a global mining major. An IGCC plant captures CO2 pre-combustion for subsequent underground storage. Following an 18 month pre-feasibility study the project was shelved on account of regulatory uncertainty.

Ottana CO2 Battery.jpeg

Ottana, Italy

Ottana is a 2.5MW / 4MWh Longer Duration Energy Storage (LDES) project that stores energy by liquifying CO2 using all proven off-the-shelf equipment. This 'CO2 Battery' energy storage technology is developed by Energy Dome and now ready to be deployed at scale in Australia.
