3.02 Firm Transfor~na~ion Service . As the load and system conditions change for Connexus energy, at its option and with approval by the City, Connexus Energy may convert this interconnection from. backup emergency transformation service normally open} to 6 Mw arm transformation service normally closed}. In the event this action is taken, the annual costs of the EMRU owned facilities will be based on peak demands at the waco substation, and shall be the ratio of the Connexus Energy peal{ demand and City peak demand times the annual cost see example}. The cost ratio for Connexus shall be limited by the 6 Mw firm load limit divided by the 28 Mw substation capacity. Monthly peals demands of the City and Connexus Energy cannot be less than the previous months peak. Monthly demands shall be the one~hour coincident demands at the time of the substation peak unless both parties agree to another method Examples of Monthly Charges: Month 1 City Connexus demand Sub demand Month 2 City Connexus demand Sub demand Month 3 City Connexus demand Sub demand Month 4 City Connexus demand Sub demand = 3,000 K'~V Connexus Energy pays 1l l ~: 2,000 Kw 2 000 Kw ~ Annual Cost + 5,000 Kw 3,000 + 2,000 = 3,500 Kw Connexus Energy pays 1112: -1,800 Kw __ .2,000 Kw ~ Annual Cast + 5,300 Kw 3,500 + 2,000 2,700 Kw Connexus Energy pays 1112; = 2,14D Kw 2,1 DD KW ~ Annual Cost + 4,800 Kw 3,500 + 2,100 3,400 Kw Connexus Energy pays 1112; =1,800 Kw _ 2,100,_K ~ Annual Cost + 5,2DD Kw 3,500 + 2,1 D0 Month 5 City acquires SOD Kw load Fram Connexus Energy.
