Exelon's (EXC) ComEd reported Tuesday the first set of new Transmission Security Agreements to ensure fairness in the cost of providing transmission service to new large loads requesting service from the grid.

The new approach protects existing customers from unfair increases in transmission rates, while supporting connection of large load projects, the company said.

The deals include revenue commitments tied to the transmission services sought by eight large customers, it said, adding that the agreements will prevent its clients from bearing responsibility for over $2 billion in transmission charges over a 10-year period.

"By having TSAs in place, ComEd can better ensure that the customers who impose very large demands on the system are paying their fair share," said ComEd CEO Gil Quiniones.
