"Emera Maine is constructing a 'series capacitor' in one of the transmission lines that travels south from Orrington substation," Emera Maine spokeswoman Susan Faloon said in a Monday email.
"Series capacitors increase the capacity of a transmission line; they allow more electricity to move through power lines without having to replace or increase the size of the existing lines.
The project is necessitated by the construction of new generation facilities here in Maine, and will allow them the ability to deliver their product to market."
Since the added capacity is required by competitors of Emera
, "who are moving power across our system, the cost of the project is covered by those generators, not Emera Maine
