Yokogawa in the power industry

In a business environment that has changed dramatically, Yokogawa continues to create new value with our partners and strives for growth along with our customers. We shall also continue as good citizens with the courage to innovate.

An industry leader on a clear path

In 2002, Eraring Energy began a revamped process to replace the original 1970s design of hard-wired electronic control equipment and computer equipment at its Eraring Power Station, one of Australia’s largest. Inviting and evaluating proposals for the latest equipment from the major control systems suppliers, Eraring Energy chose Yokogawa.

“For flexibility, experience, and commitment, we selected Yokogawa”
Michael Mortiss, Project Manager of Eraring Energy

“Our decision to carry out the revamping project was based on the need to maintain a competitive advantage in the Australian deregulated electricity market. Maximizing plant availability for at least another 20 years, timely returns to service of each unit, and efficiency gains were also significant project drivers.”

“While there are several very capable control systems vendors, Yokogawa provided the most completely integrated solution of the plant control system, training simulator, plant asset management system, and plant information and management systems. Yokogawa’s flexible approach to design and implementation of large power plant revamp projects, a team of experienced power plant engineers, and commitment to meeting all-important project outage schedules were further reasons for selecting Yokogawa.”

“We had already purchased other Yokogawa equipment such as transmitters and paperless chart recorders for our plant, and had received excellent service and ongoing support.”

“The ability to operate flexibly gives us a competitive advantage”
Jeff Hogan, Instrument and Control Team Manager of Eraring Energy

“Yokogawa took advantage of the flexibility of its equipment to suit the existing installation. Where possible, the new equipment slotted into existing cabinets, reusing existing field cables, terminations, cabinets, and connectors. New equipment was wired and tested in the factory. This avoided disturbing most existing cabling and greatly sped up installation and commissioning times.”

“The new control equipment makes fault finding a breeze, while the new graphic displays show us all the details we need.”

“The asset management system allows us to directly monitor and manage all smart field devices from our workshop.”

“The renovated units are now more flexible and responsive than before, giving the station additional advantages in a highly competitive electricity market. The refitted control room is state-of-the-art and provides a quiet and stress-free operating environment for our staff.”

“Expectations exceeded, our plant was back in operation ahead of schedule”
Michael Mortiss, Project Manager of Eraring Energy

“Yokogawa has exceeded our expectations, bringing each revamped unit back into reliable service ahead of schedule. Utilizing a full replica simulator, our engineering team and Yokogawa fully tested the new logic and control configurations before they were loaded on the actual plant. This significantly reduced the time needed for site commissioning and avoided plant trips during commissioning. Being thoroughly trained on the new screen-based control system training simulator, our operators were well prepared for the new control scheme in time for plant commissioning. This assisted in ensuring an uneventful, smooth return to service.”

“Supported by the high-level operational and maintenance diagnostics, together with strong local support from Yokogawa, we are sure that Eraring Power Station will secure high plant availability for a further 20 years.”
