COGENERATION PLANT POWER DELIVERY, DOMINION ENERGY, INC. WASHINGTON, D.C.

The Public Service Commission of the District of Columbia authorized the construction and operation of a cogeneration facility on the Georgetown University Campus. During public hearings on this project, ESI presented expert witness testimony, both written and oral relative to the electric and magnetic fields associated with the transmission of electric power from the cogeneration plant through a residential area.

ESI made magnetic field calculations for the proposed transmission line and implemented field management methods into the design. Magnetic field EMDEX measurements were also made in strategically selected homes located adjacent to the transmission line right-of-way to provide a base comparison case.

REDUCTION OF MAGNETIC FIELDS ASSOCIATED WITH POWER DELIVERY AND USE- EMPIRE STATE ELECTRIC ENERGY RESEARCH CORP. (ESEERCO/EPRI)

There is concern that exposure to power frequency magnetic fields may incur health risks. However, such as not been demonstrated conclusively. Hence, the electric power industry has adopted the prudent policy of conducting research to resolve uncertainties and develop solutions for minimizing magnetic field exposure.

ESI under subcontract to IIT Research Institute (IITRI) had the responsibility for characterizing and evaluating magnetic field management approaches for overhead and buried transmission and distribution lines, and within and about substations.

This research project produced a comprehensive perspective of power frequency magnetic fields. Important sources and their characteristics were identified. Methods for managing fields by reducing intensities or minimizing exposure were evaluated. Needs for reducing uncertainties about power frequency magnetic fields and their management were also identified.

MAGNETIC FIELD CALCULATIONS-UTAH POWER, SALT LAKE CITY, UT.

Magnetic field intensity calculations were made for a number of Utah Power transmission lines. The perturbing effects on the fields by a nearby buried pipeline were evaluated.

MAGNETIC FIELD EXPOSURE ASSESSMENT-OAK PRAIRIE CONCERVANCY GROUP, LIBERTYVILLE, IL.

The field exposure over a proposed residential development from nearby overhead transmission lines was determined. Measurements of the fields produced by the existing power lines over the area were made. Predictive computer calculations of the fields produced for various power circuit loading scenarios were also made.

MAGNETIC FIELD EXPOSURE ASSESSMENT - DUPAGE COUNTY DIVISION OF TRANSPORTATION, WHEATON, ILL.

Assessment of magnetic field intensities on an existing power line right-of-way was made based on both computer modeling calculations and field measurements. The magnetic field effects of circuit upgrade by the electric power company, i.e., the addition of two additional circuits to the right-of-way were predicted through computer modeling. This information provided input for the preparation of written testimony relative to concerns raised by a number of parties.
