ENMAX Power Corporation (ENMAX) is replacing two 138-25kV 30 MVA transformers with two 30/40/50 MVA transformers and add a 138 kV circuit breaker at ENMAX No. 7 Substation located in SW Calgary, to maintain restoration capability and accommodate load growth. The Substation is located at 718 – 101 Street SW, Calgary.
