Data centre developers consider gas power amid grid connection delays

Data centre developers in the UK and Australia are exploring gas-fired power solutions to bypass significant electrical grid connection delays.

In Cardiff, UK, developer Curtis Hall has proposed a temporary energy centre for a project on the site of the Cardiff East Park and Ride. The project requires 150MW of grid capacity, but estimates suggest full connection may not be available until between 2030 and 2034. To begin operations sooner, the developer is modeling a temporary facility using up to 49.9MW of gas-fired generation, which could operate from July 2028 until approximately July 2033. The company noted that gas turbines were included in assessments as a worst-case scenario for emissions and noise, while alternatives like hydrogen-powered fuel cells remain under consideration.

In Moss Vale, Australia, a proposed 16.5-megawatt gas-fired power station is undergoing scrutiny in the Land and Environment Court. The hearing is examining whether the local grid can support a massive nearby data centre and addressing concerns regarding long-term gas emissions. The applicant has proposed conditions including annual reporting to the Clean Energy Regulator and a commitment to transition away from natural gas within two years if green energy alternatives become feasible.
