Wärtsilä to provide O&M advisory services to Hawaiian Electric

Finland-headed marine, oil, and gas technology major Wärtsilä Corporation has announced that it has signed a Maintenance and Operational advisory agreement with Hawaiian Electric Company for its 50 MW biodiesel-fueled Schofield Generating Station, located on the island of Oahu. The 10-year agreement will help the utility to maximize the availability and efficiency of the rapid response power plant that is primarily used to meet peak loads.

According to a statement, the Maintenance and Operational advisory agreement between Wärtsilä and Hawaiian Electric Company was executed in May 2018. It responds to a variety of Hawaiian Electric’s needs, ranging from maintenance support, technical support, and reduced outage time while helping to control cost.

The agreement covers operational support, maintenance planning, major maintenance, quarterly site audits, Industrial Control Systems (ICS), cybersecurity patching services, and scheduled OEM spare parts.

Located on the island of Oahu, 40 km from Honolulu, the 50 MWe Schofield Generating Station is operated on biodiesel with ultra-low sulfur diesel as a secondary fuel and has the ability to use biogas or natural gas in the future. Supplied by Wärtsilä, the plant will also provide “black start” capability, which improves resilience in the event of natural disasters such as hurricanes or tsunamis.

Ensuring reliable and efficient operations of the plant is important for the island’s energy resilience and achievement of renewable energy goals. Our partnership with Wärtsilä will help the power plant meet its goals in a cost-effective manner, said Michael DeCaprio, Power Generation Manager at Hawaiian Electric.

Renewable balancing services

On Oahu, the installed capacity of solar PV systems is the highest per capita in the US. Therefore, it is crucial to have fast- starting generation capability that can respond to changes in wind and solar power generation.

In addition, Hawaii’s renewable portfolio standards require utility generation to be 30 percent renewable by 2020, 40 percent by 2030, 70 percent by 2040, and 100 percent by 2045. The Schofield Generating Station will help Hawaiian Electric achieve those benchmarks. The fast-response power plant increases flexible power generation and supports Hawaii in reaching its target of 100 percent renewable energy by 2045.

We are thrilled to work with Hawaiian Electric Company to maximise their revenue retention through smart technologies and digital services. At the same time, we want to help them to comply with cyber legislation and to ensure power generation, even under exceptional natural conditions, said Walter Reggente, Vice President, Americas, Wärtsilä Services.
