Northern Power to Build Grid-Connected Power System

Vermont-based Northern Power Systems, Inc., announced today that it has been commissioned to deliver an energy efficient, on-site power system to the One Market Street office complex in downtown San Francisco, owned by Equity Office Properties Trust (NYSE: EOP).
Equity Office is the nation's largest publicly held office building owner and manager with a portfolio of 767 buildings comprising 127.4 million square feet in 21 states and the District of Columbia. With 1.5 million square feet of commercial space occupying an entire city block, One Market is one of the premier office buildings in San Francisco's financial district.
When the 1.5 megawatt system is completed early next year, it will become what is believed to be the first commercial on-site electric power system to be fully interconnected with Pacific Gas & Electric's downtown San Francisco electricity grid.
The advanced cogeneration system consists of three natural gas-fired generators and a sophisticated heat recovery process, which converts waste heat from the generators and their exhausts into steam. The steam will be used to heat the building. Northern is providing overall system design, engineering and commissioning. Northern is also supplying the generators and an automated control system designed to maximize system efficiency.
Northern believes that this will be the first cogeneration system to be interconnected to the downtown San Francisco utility grid in full compliance with the Pacific Gas & Electric's Rule 21 Interconnection Standards. Running in parallel with the utility grid allows the system to meet as much of the building's electricity demand as possible, while the utility meets any needs in excess of the system's capacity. By running near full capacity, the system delivers maximum electrical efficiency. Northern's integrated control system also maximizes utilization of the waste heat from the generators, further increasing overall system efficiency.
The cogeneration system, scheduled for installation in February 2003, can deliver up to 30% of One Market's electricity and 85% of its steam needs for its space heating system.
Northern's power system is also considered a "green" system. In recovering waste heat, the system's overall fuel efficiency rises to approximately 60%, compared to typical efficiencies of 30% from utility-produced power. Doubling fuel efficiency can reduce greenhouse gas emissions by up to 40%. These higher fuel efficiencies also qualify Equity Office's new system for an incentive rebate from the Self-Generation Incentive Program of the California Public Utility Commission (CPUC). This program was established in 2001 to encourage on-site generation to reduce peak demand and avoid rolling blackouts such as those recently experienced by the state.
"Equity Office is leading the commercial real estate market in actively implementing power solutions that make sense from a power security and from an environmental standpoint," said Thomas Smith, Vice President of Energy Operations at Equity Office. "Teaming with Northern Power Systems to create this innovative approach to energy supply is fully consistent with our commitment to maintaining superior quality of service to our tenants, improving the efficiency of our systems, and lessening the impact of our operations on the environment."
Jito Coleman, president and CEO of Northern, stated, "We are fortunate to work with a company whose people recognize that power security and environmental benefit are not mutually exclusive. All of us at Northern are happy to help Equity Office reach its goals through the design and installation of this innovative and highly efficient cogeneration system."
