Rolls-Royce announced has signed a four-year contract to provide US utility PSEG with digital analytics service to improve plant efficiency at PSEG’s two nuclear plants at Salem and Hope Creek in New Jersey.

The contract follows a six-month pilot scheme that found 40% of planned maintenance activities did not need to be conducted as regularly as scheduled.

Rolls Royce’s T-104 service uses global operating data to provide best-in-class asset management services. Paul Tobin, Rolls-Royce, Executive Vice President – Nuclear, said: “Big Data analytics is a core competency at Rolls-Royce and the huge savings identified in the pilot period for PSEG show the true value that we can deliver for our customers.” The system was developed originally for the company’s aerospace business to monitor and analyse vast amounts of data continuously generated by aircraft engines. “We’re now applying the same know-how, coupled with our worldwide nuclear operating data and expertise, to deliver high-value solutions for the nuclear power generation industry,” he said.

Rolls-Royce will have employees embedded with PSEG so that the two organisations can work closely together to use Rolls-Royce’s demand-driven forecasting data. This approach will reduce overall preventive maintenance, improve equipment reliability and provide a reduction in material consumption, leading to overall reduced costs for PSEG.
