Acoma Forms a Tribal Utility Authority ; Acoma Utility Authority (AUA)
Accounts located on The Pueblo of Acoma Spend $1,750,000.00 per year with the CDEC, based on CAR
Current Electrical Usage According to the CAR report is 22 million kWh per yearCurrent Line conditions will not allow AUA to sell excess or renewable power back to the GridCurrent Line conditions are described as “Loaded” possibly affecting growth capacity for Acoma Economic DevelopmentAUA – assumes the current line inventory, meters and accounts located on the Pueblo of Acoma from CDECAUA – can purchase power at wholesale: resell it or self generate electric power with Natural GasAUA can not disconnect from CDEC and create a new wholesale power supplier without building or leasing new Sub Stations: estimated cost given by PNM of 5.5 million for Substation.AUA could self generate enough power in capacity blocks to meet current needs and build for growth.AUA can self generate electricity with 6 to 7 engines for about 0.072- 0.074 cents per kWh this includes Fuel, Maintenance, and 20 year debt service at 3.12%. AUA can own or lease back the generatorsAUA can purchase wholesale electricity for about the same costs as above from various resourcesAUA would have a 0.0353 Cost of distributing the power either wholesale purchasing or self generating power
AUA can reduce Fuel costs with Inter-tribal natural gas agreements and Capacity Load Generation RatiosAUA could also form a Natural Gas Utility sharing infrastructure costs

Severing ties with CDEC requires Acoma to take full responsibility for its electrical energy supplies.Acoma will be able to access electric supplies through either the wholesale power market or by self-generating if economically beneficial.Acoma has no experience owning, operating or managing electrical energy supplies or systems.
CDEC will facilitate the transition to Acoma's control. Federal agency support for this effort is in place, and extensive private sector support is available during the transition period to Acoma's direct operational control.
Acoma will be forced at a minimum to own/operate its electrical distribution system.
Acoma will be able to develop tribal expertise to operate the system, translating into higher reliability than at present, plus development of high skill / high wage employment for tribal members. Acoma can call upon a variety of federal and private sector assets to assist in managing this system.
The financial exposure to the tribe of owning and operating the electric supply system is currently not quantified.
Acoma can call upon financial support from a variety of federal agencies to cover some/all of its capital and operating expenses.16Risks/RewardsSlide17
Significant risks of incurring higher electric utility costs than available with a continuing retail relationship with CDEC.Acoma will create the opportunity to "pay itself" for services now provided by outsiders, significantly softening the impact of possibly higher costs. The potential for incurring higher costs may be mitigated as Acoma insulates itself from expected high costs of regional utilities forced to add additional emission controls to, or from decommissioning of, coal fired power plants. Historically low prices and low forecast inflation in natural gas prices provide Acoma with a low-cost entry opportunity for self-generation. Having two of the largest interstate gas pipelines in the US cross Acoma land provides unique opportunities to access and obtain price concessions for natural gas. Rapid historic retail and wholesale price increases imposed by regional electric utilities can be largely avoided by self-generating.
By CDEC withdrawing as a retail electricity provider, Acoma's electrical reliability may suffer.
Reliability risks under a wholesale power purchase arrangement would be the same as with CDEC. With self-generation, very high reliability can be built into the system by adding conservation measures, automated systems for controlling demand such as cycling air conditioning loads under emergency conditions, or having an additional generator on standby.
New Commercial AccountsAcoma Utility Authority would have the option of setting rates for all consumers including existing commercial accounts. Currently there is approx. $630,000.00 in yearly revenue from 126 small commercial accounts. These rates could be altered slightly higher and AUA would be able to make immediate profitsRetain $500,000.00 dollars of salaried positions on PuebloAcoma Utility Authority could now offer New Large and Medium size commercial accounts highly reliable electric power.
- High Capacity Electricity to supply CNG Gas Station Operations
- Reliable Capacity for Call Center and Warehouse Operations
- Distribution and Light Industrial could easily be supported
