As power companies confront the challenge of shifting to more
sustainable energy sources while also achieving reliable and
cost-effective supplies, GHD has helped Horizon Power trial
emerging energy storage technology in a microgrid.
GHD has provided engineering procurement and construction
management services for the integration of a 2 MW / 2 MWh battery
at the 18 MW Mungullah gas-fired power station in Carnarvon,
Western Australia. By enabling one generator to be switched off,
rather than running as spinning reserve in the event of faults or
demand spikes, the battery will enable fuel and cost savings. The
project may also allow for more renewable energy to be integrated
into the local microgrid.
Servicing regional towns and communities spread across 2.3
million square kilometres, Horizon Power operates Australia's
largest portfolio of remote microgrids, or isolated power systems.
The battery storage project is part of the company’s focus on
incorporating new technologies to achieve much higher levels of
renewable energy over time and deliver more choice for end
“As our engineering and project management partner, GHD, has
been a key factor in the success of this cutting edge project. More
broadly GHD is supporting our aim to embrace new technology, drive
the increased uptake of distributed energy and improve Horizon
Power’s capability with microgrid technology,” said Frank Tudor,
Horizon Power Managing Director.
Brett Whisson, Horizon Power’s Project Director said the trial
also aims to investigate whether battery storage could support the
installation of more distributed renewable energy in the region,
which already has one of the highest penetration levels of all of
Horizon’s micro grids, with 121 Photovoltaic (PV) installations
totalling 1.3 MW in capacity.
“We are proud to help energy companies adapt to a complex future
shaped by disruptive forces. This project showcases the capability
of batteries to provide crucial spinning reserve functions in a
microgrid. We are eager to explore the other modes of operation
such as ‘peak lopping’ to reinforce the power station in periods of
highest demand,” said Paul Buch, GHD’s Power Manager in WA.
GHD provided a variety of services for this project, from
specifying the requirements and evaluating different battery
options to designing and implementing the systems that integrate
the batteries into the micro grid.
The battery – provided by Chinese company, Tianjin Lishen
Battery – has been tested off site and on site under GHD
supervision. “The project team was impressed with capability of the
battery especially the response times which exceeded expectations
during critical commissioning tests. We also maintained a strong
safety culture while meeting the project schedule,” says Ben
MacDougall, GHD’s Project Manager.
