This is an off-river pumped hydro project in Queensland of nameplate capacity 600MW and 20 hours storage. The power station is close (20km) to a 275kV transmission line. The lower dam is adjacent to an intermittent but reliable creek and in a high rainfall area. The project is nearby a high demand area and close to announced solar projects. The head is relatively high at 480m. Socially, the site is close to regional towns with skilled construction and operations staff and in an area affected by under-employment.
Located close to wind and solar farms in Queensland this project has a nameplate capacity of 300MW and 33 hours storage. The power station is close to a 275kV high voltage transmission line. At 312m head, this project falls in the midrange for head and its environmental risk is low. It is in an area of engaged local farmers with an appetite for renewable energy projects.
This site has multiday storage, providing a very attractive metric for cost per kWh for an 80MW nameplate capacity. All the land is on one title and the owner is open to selling. The site is attractive due to a terrain which is well suited to efficient dam construction and permits a large storage volume. It is an area with distinct seasonal wind patterns which suggest long duration storage would be useful.
This 90 to 200 MW power station is located on a site with very suitable terrain, with little environmental risk, interested landholders, supportive local council, and high local renewable energy installations already in place. The site qualities encourage long duration multiday storage which lowers the cost per kwhr for the project. It is close to various transmission options.
This project has an advantage of an existing lower dam and land for the project is owned by the local authority. The lower water body for this project is a water supply dam, so is backed by drought resilience measures which means that the minimum operating level is not expected to be encountered. This project is designed for 20 hours operation at full power of 60 MW.
This is the largest of the project opportunities at 1,400 MW with 20 hours of storage. It will connect to an unconstrained hub on the grid. Should this proceed it would be a project of national significance and would provide dispatchable capacity at half the cost of the headline Snowy 2 project. It would also catalyse and be the anchor for a renewable energy hub.
This project has one of the best trajectories for early completion and low regulatory risk because of its co-location with the footprint of a well-advanced windfarm. It has close proximity to two major 330kV transmission lines, has low environmental risk and is located in a proactive local government area close to other renewable energy projects, and engaged landowners. This project has a nameplate capacity of 600MW and 20 hours storage and when matched with approriate wind and solar assets can replace retiring coal fired power.
