Hanmer Springs Capstone Generation Project

Hanmer Springs

Capstone Generation Project


First in the World Using Geothermal Methane as a Fuel Source

Problem

Hanmer Springs was flaring its geothermal methane and wanted instead to use it to generate electricity.

Solution

DETA identified, developed and delivered the first Capstone generation project in New Zealand, and the first in the world using geothermal methane as a fuel source. DETA initially developed a business case to utilise flared methane at Hanmer and identified that a Capstone Turbine would offer the best generation potential given a variable fuel supply.

DETA then project managed the entire project, from preparation of contracts for equipment and contractors, through to site management and commissioning.

Outcome

The result has far exceeded the initial estimates and is testament to the partnership approach that DETA takes to its projects.
