West Penn Power Company (West Penn) appeals from a decision of the Pennsylvania Public Utility Commission (PUC) which ordered West Penn to reimburse two customers for 75% of the costs of purchasing and installing isolation transformers. For the reasons set forth below, we reverse the order of the PUC.

This action arose from two complaints filed with the PUC by dairy farmers (complainants) against West Penn.*fn1 The complaints alleged that neutral to

    earth voltage (stray voltage) from the neutrals on West Penn's transformer was adversely affecting complainants' cows, and was causing milk production to decrease.*fn2 The complaints also alleged that after West Penn had separated its neutrals from those of the complainants, the stray voltage levels had decreased. For safety reasons, West Penn would not allow the neutrals to remain separated. In order to alleviate the problem, the complainants each installed an isolation transformer, which substantially reduced the stray voltage levels. The complainants sought to have West Penn bear the costs of purchasing and installing this corrective equipment.

At the hearings before the administrative law judge (ALJ), each complainant offered testimony and documentation to establish the connection between West Penn's equipment and the stray voltage problem. West Penn offered testimony and documentation to establish that the problem was attributable to the special milking equipment on the complainants' farms. Both West Penn and the complainants agreed that only 20% of all dairy farms are affected by stray voltage, due to the location of the farms on the utility's power distribution circuit.*fn3

The ALJ made twenty-five separate findings of fact, including a finding that cows are more sensitive to the presence of stray voltage than other farm animals. The ALJ concluded that the stray voltage problem is one unique to dairy farms. The ALJ also found that West Penn's use of the National Electric Safety Code as a guide for grounding its distribution circuits was reasonable. In his conclusions of law, the ALJ stated that while there is a definite need for improvement in the manner in which electric service is provided to dairy farm customers situated near the end of the distribution line, the evidence presented was "legally insufficient to prove that the service and facilities provided by [West Penn] are unreasonable, unsafe, inadequate, insufficient, or unreasonably discriminatory, or otherwise in violation of [§ 1501 and § 1505 of the Public Utility Code (Code), 66 Pa. C.S. § 1501 and § 1505]." The ALJ dismissed both complaints, but also recommended that the PUC conduct an informal investigation to determine the extent of the stray voltage problem in the delivery of electrical service to dairy farms in Pennsylvania.

On appeal, the PUC adopted the ALJ's findings of fact, but held that the complainants had sustained their burden of proof, and sustained the complaints in part. In its opinion, the PUC noted that the record was clear that the stray voltage problem was not universal with all dairy farmers, but that in this particular case the complainants had received an excessive level of stray voltage. Because the cost of determining the source of the stray voltage would exceed the cost of on site correction of the problem, the PUC ordered that the parties must share in the responsibility of reducing the ...
