entities involved in navajo marketing
Entities Involved In Navajo Marketing
  • Western Area Power Administration (Western) – An agency of U.S. Dept. of Energy responsible for marketing power from Federal generation including NGS.
  • Bureau of Reclamation (Reclamation) – An agency of the U.S. Dept. of Interior responsible for water and power projects in the Western U.S. Reclamation has a 24.3% entitlement in NGS for the Central Arizona Project (CAP).
  • Central Arizona Water Conservation District (CAWCD) – A multi-county water district that operates and maintains the CAP.

hoover power plant act of 1984
Hoover Power Plant Act of 1984
  • Directed Secretary of Energy (Western) to market NGS power surplus to CAP pumping and desalinization facility requirements
  • Required marketing of Navajo Surplus in accordance with Plan adopted by the Secretary of Interior (Reclamation) after consultation with Western, the Governor of Arizona, and CAWCD
  • Marketing in accordance with preference requirements under Reclamation Law and Western’s Marketing Criteria

10

hoover power plant act of 1984 cont
Hoover Power Plant Act of 1984(Cont.)
  • Plan required to optimize Navajo Surplus and provide assistance in the repayment of CAP.
  • Allows for additional rate components (rates components in addition to cost based rates).
  • Rates shall not exceed levels that allow for an appropriate saving to the contractor

11

original navajo marketing plan
Original Navajo Marketing Plan
  • Original Plan was adopted on December 1, 1987 by Reclamation on behalf of the Secretary of Interior.
  • Provided for marketing of Navajo Surplus under long-term contracts through September 30, 2011.
  • Provided for up to 400 MW of fixed capacity and energy sales with 760 MWh of energy per MW of capacity.
  • The Plan also provided for exchanges of 150 MW of the 400 MW (and associated energy) with a return of the energy in the same operating year.

12

original navajo marketing plan cont
Original Navajo Marketing Plan(Cont.)
  • The amounts available to market were based on a study of CAP water delivery and load projections.
  • The rate for this capacity and energy included a market based capacity charge (rate component) of $72 per KW-year plus the actual cost of the energy and administrative costs. The rate component is used to repay bonds issued by CAWCD for construction of certain CAP facilities.
  • Also allowed for other arrangements for any NGS capacity and energy not marketed under the sale of up to 400 MW capacity and associated energy or exchanged.

13

original navajo marketing plan cont1
Original Navajo Marketing Plan(Cont.)
  • Provides for first opportunity for new contracts to Long-Term contractors. If such contracts are executed they must be entered into by October 1, 2007.
  • Provides that CAWCD’s allocation of Hoover power from Arizona Power Authority is used to serve CAP pumping load to increase the Navajo Surplus available.

14

original navajo marketing plan cont2
Original Navajo Marketing Plan(Cont.)

Uses the exact order of priority from Conformed Criteria & Hoover Act of 1984:

1. Preference entities within Arizona.

2. Preference entities within the Boulder City Marketing Area.

3. Preference entities in adjacent Federal marketing areas.

4. Non-preference entities in the Boulder City Marketing Area.

15

contracts executed under original navajo marketing plan
Contracts Executed Under Original Navajo Marketing Plan
  • All Navajo Surplus is currently sold under three Long-Term sales contracts through September 30, 2011.
  • All three contracts are with SRP. Other entities received allocations but did not execute contracts.
  • Contracts provide for first opportunity for new contracts after September 30, 2011. If new contracts are agreed to they must be executed by October 1, 2007.

Proposed Amended

Navajo Marketing Plan

18

why is amended plan required
Why Is Amended PlanRequired?
  • Current contracts expire Sept 30, 2011.
  • Amendment of the Plan by December 31, 2007 is a requirement for key elements of the Arizona Water Settlements Act to be effective.
  • Arizona Water Settlements Act amends the uses of Navajo Surplus revenues.

19

proposed amended plan key elements
Proposed Amended PlanKey Elements
  • Proposed Amended Plan was developed by Reclamation in consultation with Western, CAWCD, and Governor of AZ
  • Provides for marketing of Navajo Surplus after September 30, 2011.
  • Developed to optimize the availability and use of revenues.
  • Annual process used to determine the Surplus to market based on water forecast and pumping requirements.

20

proposed amended plan key elements cont
Proposed Amended PlanKey Elements (Cont.)
  • Utilizes CAWCD’s power scheduled from Hoover for CAP pumping to increase Navajo Surplus.
  • Standard market products are used. Products may be sold as plant contingent.
  • Rates developed annually based on competitive process w/appropriate saving.
  • Provides for marketing of the small amounts of Navajo Surplus not captured in the annual process under other appropriate arrangements.

21

proposed amended plan key elements cont1
Proposed Amended PlanKey Elements (Cont.)
  • AZ preference entities provided first opportunity.
  • Use of revenues as set forth in the Colorado River Basin Project Act as amended by the Arizona Water Settlements Act.
  • Allows for new contracts entered into under first opportunity provisions of Original Plan. Power sold under such new contracts would not be included in the annual marketing process.

22

optimize surplus
Optimize Surplus

Original Plan

Proposed Plan

  • Surplus sales are structured around current water operations on an annual basis
  • Allows flexibility in O&M of the system needed to ensure reliable operation
  • Allows flexibility to respond to shortages or other changes in the water available to CAWCD from the Colorado River
  • Surplus availability determined through a single long-term projection of water deliveries
  • Little flexibility for annual changes in O&M of the system
  • There were no changes in water deliveries caused by water shortages anticipated during this period

28

optimize surplus cont
Optimize Surplus(Cont.)

Original Plan

Proposed Plan

  • Anticipate that no net power purchases required on annual basis (some daily balancing required)
  • Sales structured to limit impact on unit starts/stops
  • Contractual commitments cause significant power purchases by CAWCD to meet pumping requirements
  • Frequent start/stops of pumps have resulted from contractual commitments under the Plan which causes wear on the units

29

financial assistance to cap
Financial Assistance to CAP

Original Plan

Proposed Plan

  • Rates developed annually based on current market conditions
  • Product sold under shorter terms limited by foreseeable water & power market conditions
  • Annual rate determination (for products not sold on multi-year basis)
  • Rates were developed based on study of the market cost of alternative generation resources
  • Products sold in long-term contracts of approximately 20 years
  • No mechanism for rate changes. Revenue remained unchanged as market prices increased

30

annual plan process
Annual Plan Process
  • Reclamation, in consultation with CAWCD determine Navajo Surplus available to market
  • Considerations are: existing contractual commitments, CAP pumping requirements, Navajo generation and other resources, and salinity facilities requirements
