Staff Proposal

 1.9% average revenue increase effective October 1, 2017  Applied “across-the-board” to all rate classes  Applied entirely to Daily System Charge/Demand Charge  BPA wholesale power rate increase is the sole driver  5.4% average increase to all BPA customers  3.8% increase to Benton PUD - $2.3M annualized impact  Additional BPA surcharge to occur in 2018 (not in the 3.8%)  “Spill-test” ordered by US District Court – cost to be determined  Benton PUD plans to absorb 2018 surcharge with cash reserves

Individual Utility Bill Comparisons

Key Factors Impacting Bill Amounts (Rates)

 Key factors that can influence utility average bills/rates:  EIA - utilities >25,000 customers must buy 9% of load from renewables  State/local taxes – different entity types pay fewer taxes  Customer density – more customers per line mile = lower rates  Customer growth – higher growth can lead to higher rates  Debt per customer – borrowing can keep rates lower in the short term

 May catch up with a utility down the road

 Cash reserves – can be used to defer/mitigate rate actions

Bonneville Power Administration

Fish and Wildlife (F&W) Program

 BPA F&W costs in 2016 – $622 million  $127 million for foregone revenue & power purchases  $495 million for program costs  Historically ≈25% of BPA costs  $16.5 billion spent (1978‐2016)

slide-21
SLIDE 21

Secondary Market Sales

21

 Influenced by:

 Retail loads:

Higher is better but reduces surplus power

 Water volume & timing: More water through turbines is better  Market prices:

Higher is better for “net-sellers” into market

How Secondary Market Sales Work

3.0₵+ kWh

Power Markets Northwest & California

Rate changes biannually; Trend is higher Price changes hourly; Trend is much lower

Excess Power Sold on Market Used to Buy Down Retail Rates

Many NW utilities have secondary market sales – particularly BPA

Customers 3.0₵ kWh + Other Costs (2016 Avg: 6.7₵) 3.0₵ kWh + Other Costs (2016 Avg: 6.7₵)

Biological Opinion (BiOp)

Federal Columbia River Power System (FCRPS)

29

 What is the FCRPS BiOp?

 Federally developed river management plan  Guides the operation of 14 dams relative to endangered fish  NOAA Fisheries lead agency

 13 threatened or endangered stocks of salmon/steelhead  2008 BiOp and 2014 Supplemental BiOp backed by:  Four federal agencies, three northwest states, majority of Tribes  Subsequently challenged by:

 National Wildlife Federation, Oregon, Nez Perce Tribe, others

Staff preliminary recommendation. Commission decision expected September 12.

slide-30
SLIDE 30

Biological Opinion (BiOp)

Recent Developments

30

 In May 2016, U.S. District Court ruled that BiOp is insufficient  Remanded the BiOp back to the federal agencies for rewrite

 Ruled that BiOp violated the Endangered Species Act and

requirements of the National Environmental Policy Act (NEPA)

 “Recommended” that NEPA process consider the “reasonable”

alternative of breaching/bypassing one or more of the lower Snake River dams

 More recently, Court ordered additional “spill-test”  Spill-test for 2018 – April thru Mid-June  Concern by federal agencies of “unintended consequences”

 Total dissolved gas levels may increase

Staff preliminary recommendation. Commission decision expected September 12.

slide-31
SLIDE 31

Biological Opinion (BiOp)

Potential Impact

31

 BPA plans to implement a surcharge for the cost of this test  Not included in the BPA 5.4% wholesale increase on Oct 1  Uncertainty as to financial impact – as much as $40M to BPA  May impact Benton PUD $0.6K to $1.2M in 2018  Staff recommendation  Based on what we know today, use reserves to absorb the one-

year additional cost impact

Equity and Fairness Issue

Fixed Cost Recovery

 Industry-wide, fixed revenues have been less than fixed costs

 Rate structure has been in place for a century  Industry saw no compelling need to change until now

 Customer-owned solar now highlighting historical rate structure:

 Solar customers use less energy from utility  Able to avoid fixed costs buried in the kWh charge rate  Non-solar customers can be disadvantaged

Daily System Charge (Base Charge)

 Flat fee per day  Intended to cover customer-related costs including:  Customer service and billing  Allocation of administrative & general (A&G)  Minimum level of distribution infrastructure needed to serve a customer  All major customer classes have a customer-related fixed charge

*Snohomish PUD has a monthly minimum bill in lieu of a monthly base charge. The monthly minimum bill is currently $15.90.

Benton PUD currently below the median

As of June 30, 2017

Median has increased by $2.75 over the past 2 years

Base Charge information has been calculated by Benton PUD staff from publicly available information from other utilities’ websites. Calculation is Benton PUD’s best effort to provide comparable information.

October 2017 Rate Increase How Should the Increase be Applied?

63

 BPA power cost increase is the sole driver for Oct 2017 increase  Since the majority of cost is variable, suggests an increase in kWh rate  On the other hand……………  Benton PUD fixed revenues are not aligned with fixed costs  Common issue for nearly all electric utilities across the nation  Rate structure misalignment can lead to greater customer inequities  Utilities across the country raising daily/monthly fixed charges

Staff preliminary recommendation. Commission decision expected September 12.

Staff Recommendation

64

 October 2017 increase entirely to fixed charges  Gradual fix to historical misalignment  Residential: daily system charge increase from $0.55 to $0.62 per day

 Increase from $16.50 to $18.60 based on a 30-day month  Consistent with increases peer utilities are making to base charges

 Other classes: increases to daily system charges and demand charges  Gradually increase base charge – over time

 Remain near the median of benchmark utilities (currently $18.75)

 Cost of Service Analysis shows residential base charge should be $27.90

Staff preliminary recommendation. Commission decision expected September 12.

Overview of Rate Making Process

Test Year Revenue Requirement

Total costs and allocations to customers to be recovered through the COSA process and rate making.

Cost of Service Analysis

Unbundling, classification and allocation of Revenue Requirement to be recovered from customer classes

Rate Design

Use the cost of service results and Rate Strategy to guide rate design. Rates should fully recover all costs not funded by reserves and/or debt.

Financial Forecast

Multi-year financial forecast to project total utility costs and initial revenue requirement for average rate impacts. Staff preliminary recommendation. Commission decision expected September 12.

COSA vs. Rate Making

 COSA is a quantitative tool to guide setting rates for each class  COSA results for each class can vary from year-to-year  Policy goals/decisions can influence how rates are set  Benchmarking rates is another tool to guide rate setting

Why 1.9% applied to all customer classes evenly?

73

 Utilizing gradualism for changes in rates  Some customers had 2015/7% increase & 2016/4.9% increase  Dampens the year-over-year impact for customers  Power costs continue to rise: affects all classes  BPA increase in October 2017  Major uncertainty with carbon legislation/regulation

Staff preliminary recommendation. Commission decision expected September 12.

slide-74
SLIDE 74

Summary and Next Steps

74

 Staff proposal: 1.9% average revenue increase

 Increase directly attributable to BPA power increase October 1, 2017  Applied across the board to all rate classes  Applied entirely to Daily System Charges and Demand Charges

 Draft rates presented to Commission at August 22 meeting  Consider adoption of new rates at September 12 meeting

 New rates would be effective October 1, 2017

Staff preliminary recommendation. Commission decision expected September 12.
