GE’s Digital Wind Farm unlocks higher production for two aging wind plants in Japan

Kinden’s 30 MW Shirama wind farm near Osaka expects to add up to five percent more annual energy production, while Kandenko’s 22 MW Chosi wind farm near Tokyo expects to boost production by up to two percent

Kinden’s 30-MW Shirama wind farm should gain a 5% boost in AEP, while the 22-MW Chosi wind farm should net a 2% higher AEP, thanks to data and analytics from GE’s Digital Wind Farm.

GE Renewable Energy has secured a five-year Digital Wind Farm services contracts for two aging wind farms in central Japan. Kinden Corporation’s 30-MW Shirama wind farm, a 7-year-old project near Osaka, will use the digital solution to increase the site’s annual energy production (AEP) by up to 5%.

Additionally, a second contract has been signed with Kandenko for the 22-MW Chosi project, a 12-year-old wind farm near Tokyo. Here, GE’s service is expected to deliver an AEP that’s up to 2% higher.

“Our Digital Wind Farm concept is starting to gain traction all over the world,” said Anne McEntee, President & CEO of GE’s Onshore Wind business. “These two projects in Japan are great examples of our lifecycle approach to services — we are using data and analytics to create new value from older machines.”

Originally commissioned in 2004, the Chosi wind farm consists of 15 units of GE’s 1.5s product. Using GE’s Prognostics and PowerUp*Services software applications, the site will implement a turbine performance enhancement strategy that involves (among other adjustments) fine-tuning the pitch angle according to the site’s real-world operating conditions.

The goal is to enhance production, reduce cost, and boost availability and productivity over the life of a wind farm.

The goal of the Digital Wind Farm concept is to enhance turbine production, reduce costs, and boost availability and productivity over the lifetime of a wind farm.

The resulting data will help the team analyze current and historical performance, and it will help predict the remaining useful life of key components in the aging machines. The Kandenko team expects the new technology to boost revenue by up to $650,000 over the remaining lifetime of the project.

Kinden Corporation’s 30-MW Shirama project near Osaka is made up of 20 units of GE’s 1.5sle wind turbines. First commissioned in 2009, the site will also receive GE’s Prognostics and PowerUp* Services applications, implementing software and hardware enhancements that utilize a new blade clearance operation mode which will help the turbines run more efficiently and increase overall plant production by up to five percent.

GE’s Digital Wind Farm concept extends to a wide variety of existing turbine models, and the apps are also compatible with the company’s new 2-MW and 3-MW wind turbines. In May, the company unveiled a new suite of Digital Wind Farm applications that were developed to enhance production and improve wind-farm profitability.

The programs are built on the Predix* software platform, the foundation for all GE’s Industrial Internet applications, and include its specialized cyber security protection for operational technology.
