- Schedule
- Contact Information
- Questions

## P-SMBP Rate Structure

- P-SMBP has one power repayment study
- Markets 10,730 GWH
- Eastern Division (UGPR-Billings, MT)
- Pick-Sloan--ED  8,742 GWH
- Western Division (RMR-Loveland, CO)
- Pick-Sloan--WD  1,988 GWH

## P-SMBP Rate Impacts

- 8th year of drought
- PRS solved at 24.78 mills/kWh
- Total Deficits for this drought $573 M       	through FY 2007
- 10 year drought debt repayment
- Proposing 3rd rate adjustment for this drought cycle (2004, 2006, and 2008)

## Slide 5

## Slide 6

## Rate Proposals

- 1- Base and Drought Adder components rate recovery method
- 2- Metered methodology for Firm capacity charge
- 3- Allocated CROD methodology for Peaking capacity charge
- 4- Eliminate the Tiered Rate for energy over    60% load factor (Eastern Division Only)

## Base Component Methodology

**Base meets costs**

**  ****Base does not meet costs**

**Initiate public process**

**Base Component Methodology**

**No change to the Base**

**Implement new Base**

## Drought Adder Methodology

** ****Drought Costs**

**Higher than projected**
**Drought Costs**

**Increase Adder**

**Drought**** ****Adder Methodology**

**Keep 10 Year Repayment**
**of Drought Debt**

**Reduce Adder**

**Automatic increase**
**up to 2 mills/kWh**

**Increase greater than 2 mills/kWh Initiate Public Process **

**Annually**

**Annually**

## Conduct preliminary review in early summer to estimate adjustment +/-
Letter sent to customers to give advance notice of estimated adjustment
Conduct final review in September to finalize adjustment +/- (up to 2 mills/kWh)
Letter sent to customers in October giving notice of final adjustment
Adder adjusted in January billing period

- Letter sent to customers to give advance notice of estimated adjustment
- Conduct final review in September to finalize adjustment +/- (up to 2 mills/kWh)
- Letter sent to customers in October giving notice of final adjustment
- Adder adjusted in January billing period

- Drought Adder Annual Process

## Capacity Rates for Firm and Peaking

- Historically Firm and Peaking have had the same rate
- Treat different products with different rates
- Peaking = CROD billing
- Firm = Load pattern billing

**$/Metered kW-Mo/Year**

**$/CROD  kW-Mo/Year**

**Firm Metered**** **

**Peaking CROD**

**Firm Capacity Charge**

**Peaking Capacity Charge**

**Proposed Capacity ****Rates**

## Eliminate the Tiered Rate

- Tiered Rate Discourages Load Management
- Consistent with WD of Pick-Sloan

## Eastern Division Rate Design

- Firm capacity based on metered capacity billing units of 17,876 MW-mo/year
- 8,742 GWH Firm Energy
- 356 MW of Peaking capacity recovered in the 50/50 capacity and energy split
- Peaking capacity based on CROD billing units of 4,272 MW-mo/year

## 50/50 Design

- Eastern Division rate is 50/50 design where 50% of the revenue requirement is recovered from the capacity rate and 50% is recovered from the energy rate:
- Firm Power Rev. Req.                  $ 214.1 Million
- Peaking Rev. Req.			 $21.8 Million
- 5% Discount Req. 			     _9.1 Million_
- Gross Revenue Req. 		          $ 245 Million

## Eastern Division Revenue

**Firm Capacity**

**Peaking Capacity**

**Firm Energy**

**50/50 Capacity/Energy Split**

**1⁄2  of total Rev. Req. ED  Energy GWH**

**Firm portion of 1⁄2 total Rev. Req. Capacity based on total firm load pattern units kW-mo/yr**

**50%**

**50%**

**Peaking portion of Capacity Rev. Req. based on total CROD units kW-mo/yr**
