162 MW Te Mihi Steamfield process design, Pump Station detailed design.

MTL Role:

Process design for the expanded Te Mihi steamfield serving the new Te Mihi Power Station and the 60 year old Wairakei Power Station. A flexible process design was required to accommodate the various stages involved with integrating the new power station. Process design covered two phase systems, separation plants, dump systems, intermediate pressure separated water systems, low pressure separated water, condensate for reinjection, and separated water reinjection systems.

Project Outcome:

The Te Mihi steamfield has been operating successfully since 2014, supplying steam and separated water to Te Mihi Power Station, and re-injecting over 3000 tonnes/day of brine.

Project Partners:

MB Century, McMahon and Sigma Consulting.
