Oliver Pacific

Chief Technology Officer

Chief Technology Officer Oliver Pacific brings more than 22 years of power generation experience in manufacturing, engineering, and field commissioning to the Spirae team.  His experience is particularly extensive with Allison, GE, Kawasaki, Yanmar (gas turbines from 1MW to 300 MW), Detroit Diesel (DDC/MTU), Electric Motive (EMD), and Caterpillar engines (250 KW to 35 MW).

Oliver worked for Valley Power Systems for 13 years, where he became operations manager for the power products division. At Valley Power Systems, he managed manufacturing and engineering with more than 100 employees and annual sales of $30 million.

He later moved to Statordyne Corporation, a manufacturer of rotary UPS systems. At Statordyne – and later at GFI Energy Ventures (acquired by Statordyne) – he served as Vice President of Engineering and as a consultant. At Statordyne he led the use of CPS systems to produce peak efficiency in diesel power plants. He also led the design of a multiple unit control system that included distributed generation, peak shaving, and on-board SCADA. Statordyne's products ranged from 500KVA to 2MVA.

Since joining Spirae in 2006, Oliver has led the development and integration of an innovative grid-management technology for Energinet.dk, the Danish transmission system operator. This project, called the Cell Controller Project demonstrates hybrid system operation of a high penetration of wind and distributed energy resources with advanced distribution functions such as self-healing and islanded operations. Significant development was put forth into new island-based controls such as frequency shedding control and islanded voltage control, islanded load restoration and islanded mode management.

At Spirae, he also led the technical design of the Renewable and Distributed Systems Integration (RDSI) and FortZED projects, that aimed to modernize and transform the electrical distribution system of the downtown area of Fort Collins, Colorado. This was accomplished by developing and demonstrating a coordinated and integrated system of mixed distributed resources that targeted at least a 20% reduction of the combined annual peak load on two distribution feeders at a single substation while delivering improved efficiency and reliability to the grid and resource asset owners.

Oliver holds a degree in engineering from Idaho State University in power generation and distribution.
