1960s

• The Brunner Island station, Pennsylvania Power & Light's second semi-outdoor, bituminous coal-burning plant, goes on line. The initial two units are the biggest yet in the company's system; a third unit is built before the end of the decade.

• Pennsylvania Power & Light establishes itself as a winter-peak electric company by aggressively promoting residential and commercial electric heating while other utilities peg their growth on air conditioning for a summer peak. Through the 1990s, the company remains the only winter-peaking utility in the PJM power pool.

• The Public Utility Commission approves Pennsylvania Power & Light's new tariff filing that, for the first time, gives a separate and lower rate to residential customers who use electric energy as the exclusive source of home heating in addition to cooking and water heating.

• The company enters a joint venture with its PJM partners to construct a mine-mouth program where electric power would be generated in western Pennsylvania and transmitted back to eastern Pennsylvania and New Jersey through more than 600 miles of high-voltage lines. The power grid are created when Keystone power plant and Conemaugh power plant go on line and interconnect with other major utility plants.

• Pennsylvania Power & Light shifts to Pennsylvania bituminous coal to lessen its dependence on the declining production of the state's anthracite fields. The company also begins using a unit train system, which delivers coal in a dedicated trainload from the mine to the power plant.

• The company begins a vigorous program of area and economic development in central and eastern Pennsylvania. Operation Trees is Pennsylvania Power & Light's solution to restore the anthracite region's landscape. Company foresters work with 139 community groups in 33 areas to plant more than a quarter-million seedlings in 1964 and 1965. Also, from 1961 to 1965, Pennsylvania Power & Light's economic development efforts help create more than 500 new businesses in its service territory.

• The company begins equipping its line fleet with hydraulics technology.

• Although women have been a part of Pennsylvania Power & Light's workforce since the 1920s, female engineers did not join the company's crews until 1968.

• The company's safety program stands as a model for the utility industry.

• Pennsylvania Power & Light begins construction of Montour power plant.

• The Hauto plant closes its doors in 1969 after 56 years of operation, and the Stanton plant follows suit three years later after 45 years of operation, ending an era for two of the company's oldest anthracite-fired power plants.
