Market Intelligence

  • According to recent statistics by PA Power Switch, Pennsylvania has experienced a statewide decline of 10,200 residential electric customers for the month of September. This is on par with the trend of monthly declines occurring since May 2018 for residential energy shopping, however, it is substantially less than August’s decline of about 12,000 accounts. Duquesne Light and Med-Ed were the only 2 of the 7 large PA utilities that experienced greater losses in September than in August, losing -211% (from -182 to -567) and -9.5% (from -1,363 to -1,493) more customers, respectively.

  • Fitchburg Gas & Electric, d/b/a Unitil, has filed new electric basic service rates for the price period of December 1, 2018 to May 31, 2019 with the Massachusetts DPU. The Residential (RD-1, RD-2) and Small General commercial (GD-1) fixed rates, which include a baked-in Basic Service Cost Adder (BSCA) of $0.00570/kWh, are projected to increase approximately 25% from $0.1056/kWh to $0.1310/kWh. This change is awaiting approval from the MA DPU.


  • Below normal temperatures are expected to arrive to the eastern US, replacing long-standing above normal temperatures and likely bringing the first frost of the year to most of the northern region.

  • A heavy concentration of below normal air materializes in the center of Texas, which is likely to be accompanied by neutral to above normal precipitation conditions.

  • Above normal temperatures take hold of the western region of the lower 48, with a high probability of warmer temperatures along the entire Pacific coast.  The northern half of the West region should see drier air with more normal precipitation occurring further south.
