Mungullah Power Station, Carnarvon
Horizon Power has embarked on a $73 million project to build, own and operate a new dual-fuel power station and transmission infrastructure to serve the growing needs of the Carnarvon community.
The project represents a significant investment by the Government of Western Australia into power infrastructure in the Gascoyne region.
The 18 megawatt power station, which will use both diesel and gas, is being built at Brown Range, about six and a half kilometres from the town centre and residential areas. It will service the needs of 6600 people for at least the next decade and has been designed to ensure extra generation capacity can be installed.
Horizon Power has worked with the traditional owners and custodians of the area, the Gnulli People, and the State Government to acquire the land for the new station. The Gnulli People have given the name for the power station as part of an agreement with Horizon Power. Mungullah is the Yinggarda word for the hill on which the power station is located.
The project is taking place in two phases, which means power will continue to be generated from the existing site for some time.
The new power station also has been designed to incorporate renewable energy sources in the future.
Horizon Power is conducting feasibility studies for the integration of renewable technologies. These studies include wind and solar sources.


Click on the questions below to see their corresponding answers.
- What are the benefits of building a new power station?
- The new state-of-the-art flagship power station will be more efficient and environmentally-friendly than the existing power station. The new station, which will meet future power demand in Carnarvon, will also be significantly quieter than the existing station, which has been operating since 1972.
- When will construction start and when will the station be operational?
- Construction will start in early 2011. Power is expected to be generated from the new power station in early 2012.
- How much will this project cost?
- The project is funded by the State Government and will cost $73 million. This includes the new power station and new infrastructure including express feeders and the Dampier to Bunbury Natural Gas Pipeline extensions. Horizon Power will build, own and operate the new power station.
- Why is there going to be a phased transition to the new site?
- A phased transition to a new power station site allows staged funding to be invested into new plant that incorporates advanced technology while maximum value is achieved from plant at the existing power station site. It also allows for a back-up power supply and smoother transition.
- What are the benefits of the new site?
- The new site has been chosen because of its distance from residential areas, which will reduce noise levels for Carnarvon residents. It is also close to the Dampier to Bunbury Pipeline, a fuel source for the power station. The site is also near land that is suitable for renewable energy generation. Feasibility studies are being conducted for the possible incorporation of renewable energy generation.
- What is a dual-fuel power station and what are its advantages?
- A duel-fuel power station involves the use of more than one type of fuel to generate electricity. Having a power station that incorporates both diesel and gas-fuelled plant means Horizon Power is not completely reliant on one type of fuel for generating power. This increases the level of security of the town's power supplies.
