Monthly natural gas rates charged by Baltimore Gas and Electric Co. have increased by as much as 18.5 percent since the start of November as a spike in gas prices last fall and the effect of increasing demand made their way to the consumer.
For an average residential customer, who uses about 90 therms of natural gas a month, the bill increased 18.5 percent, to $61.27, in January, from $51.69 a year ago.
The cost has risen because of increases in the Purchased Gas Adjustment, the portion of the bill that allows BG&E to reflect increases and decreases in natural gas prices in its charges.
