Schott to Renovate Power System at National Park

Schott Applied Power Corporation (SAPC) has been chosen by the National Park Service to renovate the power system at Natural Bridges National Monument near Moab, Utah.

Rocklin, California – January 31, 2003 [] The system, which uses a hybrid design of photovoltaics (PV), batteries and diesel generators, was the largest of its kind at the time of installation in 1980. While the solar arrays continue to produce energy today, over time the system’s battery backup and storage components have degraded and its DC to AC inverters have become obsolete. Consequently, the diesel generators run longer to keep pace with the monument’s energy needs, causing increased noise, exhaust, fuel deliveries and potential for spills. “In terms of the delivery of energy, Natural Bridges National Monument is very remote. We’re over 30 miles from the nearest electrical grid system. It’s not feasible, cost effective or inline with the ‘Greening of the National Parks’ initiative to run power lines into the monument,” said Greg Dudgeon, superintendent, Hovenweep and Natural Bridges National Monuments. “After an extensive research and bidding process, we chose SAPC to help bring our system back to its full potential – and a little more, as SAPC’s solution uses only a quarter of the space of the original system’s components.” The National Parks Service instituted a program called “Greening of the National Park Service” in July 1999. Conserving the parks and wildlife and to keep them unimpaired (as pure as possible) is the goal of the program. One way to accomplish this is through the use of solar systems, which reduce the pollution and environmental harm caused by burning fossil fuels and reduce or replace generator run times and the associated consequences mentioned earlier. “Schott Applied Power is well qualified to help the Monument upgrade and renovate its energy system. We are the leading supplier of solar power systems and products and have been for the last 12 years. We’ve supplied thousands of systems to state and local government agencies, the U.S. Geological Survey, Forest Service, Bureau of Land Management, the U.S. Military and the National Park Service, powering their critical energy needs, often in rugged, remote areas,” said Scott Williams, manager of industrial and government sales for SAPC. “We’ve also supplied and installed some of the largest solar/hybrid genset systems to the federal government, including a 161 kW PV system for the National Park Service in Glen Canyon National Recreation Area and a 155 kW PV system for the U.S. Navy on a remote island off the California coast.” The batteries, inverters and controls selected for this project represent the latest technologies available for solar power systems. The renovation will consist of disposing of the old batteries and replacing them with a 319 kW C & D battery bank and 100 kW of Advanced Energy inverters and new controllers. Work is expected to begin this month and finish in April 2003.
