“AltaGas is very pleased to be able to work collaboratively and successfully with all parties in the Washington, D.C. area,” said David Harris, President and Chief Executive Officer of AltaGas. “This agreement meets our expectations and delivers tangible benefits to all parties, customers and the region. Together, AltaGas and WGL will be in an even stronger position to deliver exceptional service at affordable rates, more investment in the community, workforce training programs, more clean energy choices for customers, and good, secure jobs.”

“For 170 years, we have dedicated ourselves to providing safe, reliable service to our customers in Washington, D.C. and our entire service territory. With today’s settlement filing with the DC PSC, we once again reaffirm our commitment to the District as we outline the many ways the D.C. community will benefit from our combination with AltaGas,” said Terry D.
