A consortium led by ABB, the global power and technology company, has signed a contract worth about 71 million euros (US$65 million) with the Indonesian state electricity supplier PT-PLN (Persero) to build a 309-km (192-mile) power line on the main island of Java.

ABB's portion of the contract is worth about 35 million euros ($32 million). The line is part of the extension of the 500-kV ultrahigh-voltage grid linking new power plants in eastern Java to the cities of Jakarta, Bandung and Yogyakarta.

ABB will lead a group of consortium partners and subcontractors and will provide engineering, design, project management, supply management and logistics for a project that will involve 4000 workers in more than 750 construction sites.

The order is scheduled for completion within 24 months and includes 750 towers weighing roughly 26,000 tons, 7500 km (4660 miles) of conductors, 380,000 insulators and a ground wire with integral optical fibers for telecommunications transmission. Roughly 70% of the power line will be installed over rice paddies, which will require a special foundation system ABB has designed for soft soil conditions.
