Central Thermal Plant – Stage 2Chippendale, New South Wales

Fit-out and commissioning of the Central Thermal Plant (CTP).

PROJECT DESCRIPTION

Due to the enormous success of Stage 1, Frasers awarded Total Construction with Stage 2 of the project which included design, procurement, construction and commissioning of the Central Thermal Plant (CTP). The work also included:

• Construction within one level of basement underneath building Block 4S and located directly adjacent to the CTP1 basement.
• 11kV grid connection to a private HV substation located in the basement.
• CTP2 electrical distribution to four adjacent buildings to provide electrical demand.
• Installation of a diesel back-up generator to provide power to essential services and keep the CTP operating at a minimal capacity.

The continued relationship with Frasers and award of the Stage 2 project firmly establishes Total as a dominant player in the polygeneration market.

OVERCOMING CHALLENGES

A considerable challenge was the Thermal Energy Storage (TES) tank which contains 500,000L of 80OC hot water. A large concrete room acts as a tank and was insulated then lined in situ. Confined space and safe buildability were a challenge, but the tank is now in operation and very effective. Over 48 hours, it loses less than 1OC to the environment. Great for dealing with the morning shower rush, all from the cogeneration plant overnight.

The project won ‘Most Innovative Project 2014’ from NSW Master Builders & ‘Best Cogeneration or District Energy Project 2014’ from Energy Efficiency Council.
