GULF POWER COMPANY ("Gulf Power", "Gulf'', or "the Company"), by and through

its undersigned counsel, and pursuant to section 366.8255, Florida Statutes and various orders of

the Florida Public Service Commission ("Commission") implementing and defining the

Environmental Cost Recovery Clause ("ECRC"), hereby petitions the Commission for approval

of the Company's final environmental cost recovery true-up amount for the period January 2016

through December 2016; for approval of the Company's estimated environmental cost recovery

true-up amount for the period January 2017 through December 2017; for approval of the

Company's projected environmental cost recovery amounts for the period January 2018 through

December 20 18; and for approval of environmental cost recovery factors to be applied in

customer billings beginning with the period January 2018 through December 2018. As grounds

for the relief requested by this petition, the Company would respectfully show:

BACKGROUND

(I) Section 366.8255, Florida Statutes, (the "Statute") authorizes the Commission to

review and decide whether Gulfs environmental compliance costs are recoverable through an

environmental cost recovery factor. Pursuant to the Statute, environmental compliance costs

include "[a]ll costs or expenses incurred by an electric utility in complying with environmental

laws or regulations . .. . " The term "environmental laws or regulations" is defined in the Statute

to include "all federal, state, or local statutes, administrative regulations, orders, ordinances,

resolutions, or other requirements that apply to electric utilities and are designed to protect the

environment." Pursuant to the Statute, the Commission shall allow a utility to recover its

prudently incurred environmental compliance costs through the ECRC which is separate and

apart from the utility' s base rates. Only prudently incurred environmental compliance costs may

be recovered through the ECRC. In Order No. PSC-94-0044-FOF-EI, issued January 12, 1994,

the Commission identified three criteria for eligibility for cost recovery through the ECRC: I)

the costs must have been incurred after April 13, 1993; 2) the activity is legally required to

comply with a governmentally imposed environmental regulation which was enacted, or became

effective, or whose effect was triggered after the company's last test year upon which rates are

based; and, 3) the costs are not recovered through some other cost recovery mechanism or

through base rates.

{2) Gulf Power initially petitioned the Commission to establish the ECRC in

Docket No. 930613-EI. The Commission considered Gulfs petition at hearings held in

December 1993 and ultimately issued Order No. PSC-94-0044-FOF-EI which established the 2

ECRC for Gulf Power and approved the commencement of recovery through initial factors

effective with the first billing cycle for February 1994. Since that initial order, Gulf has

periodically petitioned for and received Commission approval for recovery of the Company's

revenue requirements associated with new environmental compliance activities consistent with

the ECRC statutes and Commission precedent. Also since that initial order and subsequent

orders of the Commission approving the Company's environmental compliance activities for

recovery through the ECRC, Gulf has periodically submitted true-up and projection filings to the

Commission with updated actual and projected costs for the various environmental compliance

activities recovered through the ECRC pursuant to Commission authorization.

(3) Consistent with the foregoing, Gulf submits its petition, supporting schedules,

testimony and exhibits as the Company's request herein for approval of ECRC factors to be

effective in calendar year 2018. As detailed in the following paragraphs and accompanying

supporting schedules, testimony and exhibits, Gulfs environmental compliance activities are

consistent with the ECRC statutes and Commission precedent for recovery of eligible activities

through the ECRC subject to the ongoing audit, review and true-up processes established by the

Commission.

FINAL ENVIRONMENTAL COST RECOVERY TRUE-UP AMOUNTS

(4) By vote of the Commission following hearings in November 2016, estimated true-

up environmental cost recovery amounts were approved by the Commission for the period

January 2016 through December 2016, subject to establishing the final environmental cost

recovery true-up amounts. Gulf has calculated its final environmental cost recovery true-up

amounts for the period January 2016 through December 2016 in accordance with the principles

and policies for environmental cost recovery established by the Commission. According to the

data filed by Gulf for the period ending December 31, 2016, the final environmental cost

3

recovery true-up amount for the period ending December 31, 2016, is an actual under-recovery

of $3,262,290. This amount is submitted for approval by the Commission to be applied in the

next period. The supporting data has been prepared in accordance with the uniform system of

accounts as applicable to the Company's environmental cost recovery and fairly presents the

Company's environmental costs to be considered for recovery through the ECRC for the period.

The environmental activities and related expenditures reflected in the true-up amounts shown for

the period ending December 31, 2016, are reasonable and necessary to achieve or maintain

compliance with environmental requirements applicable to Gulf Power Company and, therefore,

the amounts identified are prudent expenditures which have been incurred for utility purposes.

ESTIMATED ENVIRONMENTAL COST RECOVERY TRUE-UP AMOUNTS

(5) Gulf has calculated its estimated environmental cost recovery true-up amounts for

the period January 2017 through December 2017 in accordance with the principles and policies

for environmental cost recovery established by the Commission. Based on six months actual and

six months projected data, the Company's estimated environmental cost recovery true-up amount

for the period January 2017 through December 2017 is an over-recovery of $11,475,260. The

estimated environmental cost recovery true-up is combined with the final environmental cost

recovery true-up for the period ending December 31, 2016, to reach the total environmental cost

recovery true-up that is to be addressed in the next cost recovery period (January 2018 through

December 20 18). Gulf is requesting that the Commission approve this total environmental cost

recovery true-up amount excluding revenue taxes, of $8,2 I 2,970 to be applied during the January

20 I 8 through December 20 I 8 recovery period.

4

PROJECTED ENVIRONMENTAL COST RECOVERY AMOUNTS

(6) Gulf has calculated its projected environmental cost recovery amounts for the

months January 2018 through December 2018 in accordance with the principles and policies for

environmental cost recovery found in section 366.8255 of the Florida Statutes and Commission

Order No. PSC-94-0044-FOF-EI. The calculated factors reflect the recovery of the projected

environmental cost recovery amount of$203,589,886 for the period January 2018 through

December 2018, less the net trueAup amount adjusted for revenue taxes.

The computations and supporting data for the Company's environmental cost recovery

factors are set forth on true-up and projection schedules that are attached as part of the exhibits to

the final true-up testimony and actual/estimated true-up testimony of C.S. Boyett filed previously

in this docket (See DN 04008- 17 and DN 06617-20 17) and the projection testimony of Mr.

Boyett filed herewith. Additional supporting data for the environmental cost recovery factors is

provided in the final true-up testimony of R. M. Markey (See DN 04008-17), the

estimated/actual true-up testimony of Mr. Markey (See DN 06617-2017) and the projection

testimony of witnesses R. M. Markey filed herewith. The methodology used by Gulf in

determining the amounts to include in these factors and the allocation to rate classes is in

accordance with the requirements of the Commission as set forth in Order Nos. PSC-94-0044-

FOF-EI and PSC- 13-0606-FOF-EI. The amounts included in the calculated factors for the

projection period are based on reasonable projections of the costs for environmental compliance

activities that are expected to be incurred during the period January 2018 through December

20 18. The calculated factors and supporting data have been prepared in accordance with the

uniform system of accounts and fairly present the Company's best estimate of environmental

compliance costs for the projected period. The activities described in the testimony of Mr.

5

Markey are reasonable and necessary to achieve or maintain compliance with environmental

requirements applicable to Gulf Power Company and the actual or projected costs resulting from

the described compliance activities are also reasonable and necessary. Therefore, the costs

identified are prudent expenditures that have been or will be incurred for utility purposes and for

which the Company should be allowed to recover the associated revenue requirements.

be replaced in the 2018 outage. The projected 2018 expenditures for this 1

line item are $1,461,250. 2

3

Q. Please describe the projected capital expenditures for the Crist Water 4

Conservation program (Line Item 1.24). 5

A. The Crist Water Conservation program is part of Gulf’s water conservation 6

and consumptive use efficiency program required by the Plant Crist 7

consumptive water use permit. Plant Crist’s consumptive use permit, issued 8

by the Northwest Florida Water Management District (NWFWMD), requires 9

the plant to implement measures to increase water conservation and 10

Q. Mr. Markey, please describe the projects included in Gulf’s 2018 projection 19

for the Coal Combustion Residuals capital program (Line Item 1.28). 20

A. Line Item 1.28 is related to the regulation of Coal Combustion Residuals 21

(CCR) by the United States Environmental Protection Agency (EPA) and 22

FDEP. For Gulf’s generating plants, these regulatory compliance 23

obligations are pursuant to either the CCR rule adopted in April of 2015 or 24

through new requirements added by FDEP to the National Pollutant 25


Discharge Elimination System (NPDES) permits issued for each of Gulf’s 1

Florida generating facilities pursuant to authority granted under the Clean 2

Water Act. The CCR rule is located in Title 40 Code of Federal Regulations 3

(CFR) Parts 257 and 261. Plant Scherer is also subject to Georgia’s CCR 4

Rule, which requires permit applications to be submitted for the facility’s ash 5

pond and CCR landfill by November 22, 2018. The projected 2018 6

expenditures for this line item total $41,024,551 which includes costs for 7

Plants Scholz, Smith and Scherer as discussed below. 8

9

Construction activities for the closure of the ash pond at Plant Scholz have 10

begun. In 2017, Gulf began construction of slurry wall. During 2018, the 11

Scholz ash pond closure includes construction of a new stormwater 12

management system, transferring CCR material upland to a dry stack area 13

within the footprint of the pond, and capping the dry stack area with closure 14

turf material. The 2018 expenditures for the Plant Scholz CCR closure are 15

projected to be $14,519,294. 16

17

Recently, Gulf began construction of the Plant Smith pond closure by 18

relocating CCR material within the footprint of the pond. In 2018, Gulf will 19

proceed with construction and associated activities to close a portion of the 20

pond. The Smith pond closure includes construction of industrial wastewater 21

ponds and a slurry wall as well as transferring CCR material upland to a dry 22

stack area within the footprint of the pond and capping the dry stack area 23

with closure turf material. The 2018 expenditures for the Plant Smith CCR 24

closure are projected to be $13,343,945. 25


The Plant Scherer ash pond is scheduled to cease operations and stop 1

receiving coal ash in 2019. Construction and related closure activities will be 2

required for several years to accommodate closure. Design and 3

construction of the Scherer dry bottom ash conversion and wastewater 4

management system will occur in 2018 and 2019. In 2018, work will be 5

performed to utilize cell 3 of the onsite landfill for ash storage. Plant Scherer 6

will also proceed with siting studies and preliminary design for a new landfill. 7

The 2018 expenditures for the Plant Scherer CCR projects are projected to 8

be $13,161,312. 9

10

Q. Mr. Markey, are you including the purchase of allowances in your 2018 11

projection filing? 12

A. No, we are not currently projecting the need to purchase additional 13

allowances during 2018. 14

15

16

Operation and Maintenance (O&M) 17

PREPARED DIRECT TESTIMONY AND EXHIBIT OF

C. SHANE BOYETT

PROJECTION FILING FOR THE PERIOD

JANUARY 2018- DECEMBER 2018

September 1, 2017

GULF POWER COMPANY 1

Before the Florida Public Service Commission 2 Prepared Direct Testimony and Exhibit of

C. Shane Boyett 3 Docket No. 20170007-EI

Date of Filing: September 1, 2017 4

Q. Please state your name, business address and occupation. 5

A. My name is Shane Boyett. My business address is One Energy Place, 6

Pensacola, Florida 32520. I am the Regulatory and Cost Recovery 7

Manager for Gulf Power Company. 8

9

Q. Have you previously filed testimony in this docket? 10

A. Yes. 11

12

Q. What is the purpose of your testimony? 13

A. The purpose of my testimony is to present both the calculation of the 14

revenue requirements and the development of the environmental cost 15

recovery factors for the period of January 2018 through December 2018. I 16

will also discuss the changes Gulf implemented as a result of the 17

Stipulation and Settlement Agreement (Settlement Agreement), approved 18

by the Commission in Order No. PSC-17-0178-S-EI in consolidated 19

Docket Nos. 160186-EI and 160170-EI dated May 16, 2017. 20

21

Q. Have you prepared any exhibits that contain information to which you will 22

refer in your testimony? 23

A. Yes, I am sponsoring two exhibits. My first exhibit consists of eight 24

schedules which are Gulf’s environmental cost recovery projection 25

Docket No. 20170007-EI Page 2 Witness: C. Shane Boyett

schedules. My second exhibit contains the calculation of the Scherer/Flint 1

credit, in accordance with provisions of the Settlement Agreement. Both 2

exhibits were prepared under my direction, supervision, or review. 3

Counsel: We ask that Mr. Boyett's exhibits 4

be marked as Exhibit No. _____(CSB-4) and 5

Exhibit No. ______(CSB-5). 6

7

Q. What environmental costs is Gulf requesting recovery of through the 8

Environmental Cost Recovery Clause (ECRC)? 9

A. As discussed in the testimony of Gulf Witness Richard M. Markey, Gulf is 10

requesting recovery for certain environmental compliance operating 11

expenses and capital costs that are consistent with both the decision of the 12

Commission in Order No.PSC-94-0044-FOF-EI in Docket No. 930613-EI and 13

with past proceedings in this ongoing recovery docket. The costs identified 14

for recovery through the ECRC are not currently being recovered through 15

base rates or any other cost recovery mechanism. 16

17

Q. How was the amount of projected Operations and Maintenance (O&M) 18

expenses to be recovered through the ECRC calculated? 19

A. Mr. Markey has provided projected recoverable O&M expenses for 20

January 2018 through December 2018. Schedule 2P of Exhibit CSB-4 21

shows the calculation of the recoverable O&M expenses broken down 22

between demand-related and energy-related expenses. Schedule 2P also 23

provides the appropriate jurisdictional factors and amounts related to 24

these expenses. All O&M expenses associated with compliance with air 25


quality environmental regulations were considered to be energy-related, 1

consistent with Commission Order No. PSC-94-0044-FOF-EI. The 2

remaining expenses were broken down between demand and energy 3

consistent with Gulf's last approved cost-of-service methodology. 4

5

Q. Please describe Schedules 3P and 4P of your Exhibit CSB-4. 6

A. Schedule 3P summarizes the monthly recoverable revenue requirements 7

associated with each capital investment project for the recovery period. 8

Schedule 4P shows the detailed calculation of the revenue requirements 9

associated with each investment project. Schedules 3P and 4P also 10

include the calculation of the jurisdictional amount of recoverable revenue 11

requirements. To prepare these schedules, Mr. Markey provided the 12

expenditures, clearings, retirements, salvage, and cost of removal related 13

to each capital project, as well as the monthly costs for emission 14

allowances. From that information, plant-in-service and construction work 15

in progress (non-interest bearing) was calculated. Additionally, 16

depreciation, amortization and dismantlement expense and the associated 17

accumulated depreciation balances, were calculated based on Gulf's 18

approved depreciation rates, amortization periods, and dismantlement 19

accruals. The capital projects identified for recovery through the ECRC 20

are those environmental projects which were not included in the test year 21

on which present base rates were set. 22

23

Q. How was the amount of property taxes to be recovered through the ECRC 24

derived? 25


A. Property taxes were calculated by applying the projected applicable 1

millage rate to the ECRC apportioned assessed value. 2

3

Q. What capital structure and return on equity were used to develop the rate 4

of return used to calculate the revenue requirements as shown on 8P? 5

A. Consistent with Commission Order No. PSC-12-0425-PAA-EU dated 6

August 16, 2012, in Docket No. 120007-EI, the capital structure used in 7

calculating the rate of return for recovery clause purposes is based on the 8

weighted average cost of capital (WACC) established from the Settlement 9

Agreement. This rate of return used to calculate ECRC revenue 10

requirements includes a return on equity of 10.25 percent for the period 11

January 1, 2018, through December 31, 2018. 12

13

Q. Have you appropriately integrated the provision of the Settlement 14

Agreement related to depreciation, amortization and dismantlement? 15

A. Yes. Beginning January 1, 2018, Gulf will implement new depreciation 16

rates pursuant to the approved Settlement Agreement. Amortization of 17

the regulatory asset resulting from the unrecovered plant balance 18

associated with the retirement of Smith Units 1 and 2 will begin January 1, 19

2018. The amortization period is 15 years. As indicated in my Estimated 20

True-up testimony previously filed in this docket, Gulf implemented 21

reduced dismantlement accruals beginning July 1, 2017. The only 22

remaining accruals are related to Coal Combustion Residuals at Plants 23

Crist, Daniel and Scherer. 24

25


Q. Is the supporting data presented in accordance with the Uniform System 1

of Accounts as prescribed by this Commission? 2

A. Yes. 3

4

Q. How has the breakdown between demand-related and energy-related 5

investment costs been determined? 6

A. Consistent with Commission Order No. PSC-13-0606-FOF-EI dated 7

November 19, 2013, in Docket No. 130007-EI, investment costs 8

recoverable through ECRC were broken down within the retail jurisdiction 9

based on the 12-MCP and 1/13th energy allocator. The use of this 10

allocator is consistent with cost-of-service studies approved in Gulf’s prior 11

base rate cases. The calculation of this breakdown is shown on Schedule 12

4P and summarized on Schedule 3P. 13

14

Q. What is the total amount of projected recoverable costs related to the 15

period January 2018 through December 2018? 16

A. The total projected jurisdictional recoverable costs for the period January 17

2018 through December 2018 is $211,656,376 as shown on line 1c of 18

Schedule 1P of Exhibit CSB-4. This amount includes costs related to 19

O&M activities of $42,515,980 and costs related to capital projects of 20

$169,140,396, as shown on lines 1a and 1b of Schedule 1P. The 21

adjustment (Scherer/Flint credit) as reflected on Lines 1.29 and 1.30 of 22

Schedule 2P and Lines 1.35 and 1.36 of Schedule 3P calculates the 23

incremental revenue requirement related to the portion of Scherer Unit 3 24

(Scherer 3) that continues to be committed to a wholesale customer 25


through a long-term contact. The Scherer/Flint credit is calculated in 1

accordance with the provisions in the Settlement Agreement, resulting in 2

ECRC being revenue-neutral regarding the incremental inclusion of 3

Scherer 3 investment and expenses. 4

5

Q. What is the total recoverable revenue requirement to be recovered in the 6

projection period January 2018 through December 2018, and how was it 7

allocated to each rate class? 8

A. The total recoverable revenue requirement including revenue taxes is 9

$203,589,886 for the period January 2018 through December 2018, as 10

shown on line 5 of Schedule 1P of Exhibit CSB-4. This amount includes 11

the recoverable costs related to the projection period offset by the total 12

over-recovery true-up amount of $8,212,970. Schedule 1P also 13

summarizes the energy and demand components of the requested 14

revenue requirement. These amounts are allocated by rate class using 15

the appropriate energy and demand allocators as shown on Schedule 6P 16

and 7P of Exhibit CSB-4. 17

18

Q. How were the rate class allocation factors calculated for use in the 19

Environmental Cost Recovery Clause? 20

A. The demand allocation factors used in the ECRC have been calculated using the 21

2015 Cost of Service Load Research Study results filed with the Commission in 22

accordance with Rule 25-6.0437, F.A.C. and adjusted for losses. The energy 23

allocation factors were calculated based on projected kWh sales for the period 24

adjusted for losses. The calculation of the allocation factors for the period is 25


shown in columns A through I on Schedule 6P of Exhibit CSB-4. 1

2

Q. How were these factors applied to allocate the requested recovery amount 3

properly to the rate classes? 4

A. As I described earlier in my testimony, Schedule 1P of Exhibit CSB-4 5

summarizes the energy and demand portions of the total requested 6

revenue requirement. The energy-related recoverable revenue 7

requirement of $34,758,056 for the period January 2018 through 8

December 2018 was allocated using the energy allocator, as shown in 9

column C on Schedule 7P of Exhibit CSB-4. The demand-related 10

recoverable revenue requirement of $168,831,830 for the period January 11

2018 through December 2018 was allocated using the demand allocator, 12

as shown in column D on Schedule 7P. The energy-related and demand-13

related recoverable revenue requirements are added together to derive 14

the total amount assigned to each rate class, as shown in column E on 15

Schedule 7P. 16

17

Q. What is the monthly amount related to environmental costs recovered 18

through this factor that will be included on a residential customer's bill for 19

1,000 kWh? 20

A. The environmental costs recovered through the clause from the residential 21

customer who uses 1,000 kWh will be $21.24 monthly for the period 22

January 2018 through December 2018. 23

24

25


Q. When does Gulf propose to collect its environmental cost recovery 1

charges? 2

A. The factors will be effective beginning with Cycle 1 billings in January 3

2018 and will continue through the last billing cycle of December 2018. 4

5

Q. Mr. Boyett, does this conclude your testimony? 6

A. Yes. 7
