July 2012 project update

July was a big month for the King Island Renewable Energy Integration Project (KIREIP). The Diesel Uninterruptible Power Supply generation units (D-UPS) have been moved into their newly constructed bays and fuel, exhaust and electrical connections have begun. All of the new high voltage (HV) switch gear has now been installed and commissioned. While the HV gear is a supporting element of KIREIP it is vital to the success of the project. It provides the connection points for the new equipment and will increase electricity supply reliability and allow the team to test new equipment while maintaining power supply to customers. 

Project elements snapshot:

Bio Diesel: results of the 20% bio dieselblend  trial continue to be assessed. A trial will start in the coming weeks using 100% Bio Diesel, this will be carried out on both newer and older styles of diesel engines installed at the power station to assess the potential impacts of using this biofuel.

Vanadium Redox Battery (VRB): investigations have indicated that decommissioning rather than repair of the inoperable VRB will be required.

Wind farm expansion: preliminary work has begun for the wind expansion, supply contracts for wind turbines will be in place in the coming months.

Uninterruptible Power Supply class Diesel engine (D-UPS): D-UPS units one and two are in the power station and being  connected to the system. Commissioning tests of these units will now be conducted before they will be put into operation on   the power system.

Energy storage system: preliminary design work has been completed for the energy storage system.  A supply contract for a nominal 2 Megawatt / 2 Megawatt hour storage system will be in place within the next few weeks.

Smart Grid:  Suppliers for the smart grid infrastructure have been selected and contracts are currently being negotiated.  The infrastructure will include a control system installed at the King Island Advanced Hybrid Power Station, as well as a wireless communication network that will communicate with a series of sensors and switching equipment installed at participating customer premises.
