Entergy Arkansas, Inc. Direct Testimony of Kurtis W. Castleberry Docket No. 17-041-U

Q. WHAT IS THE PURPOSE OF YOUR DIRECT TESTIMONY? 1

A. The Company executed a proposed 20-year power purchase agreement 2

(the solar “PPA” or “Agreement”) with Chicot Solar, LLC (“Chicot Solar”)3 3

on June 19, 2017, for a renewable energy resource. The Chicot Solar 4

Project (“Project”), which will be located near Lake Village, Arkansas, is 5

planned to be a 100 MW solar photovoltaic project interconnecting to the 6

existing Lake Village Bagby to Reed 115 kV transmission line, #971. 7

As was the case with the Stuttgart Solar proceeding, my direct 8

testimony supports the Company’s request for a finding that the long-term4 9

100 MW solar PPA is unique and in the public interest and that the 10

Company’s Application should be approved by the Commission. In this 11

support, the Company asserts, consistent with Act 1088 of 2015 (“Act 12

1088”), that 1) the cost of the PPA is reasonable and prudent; 2) the PPA 13

will provide savings for retail customers as compared to other generation 14

and power supply options over the term of the PPA; 3) the PPA is required 15

by public convenience and necessity; 4) the PPA is necessary to 16

supplement or replace the utility’s existing generation sources; and 5) 17

approval of the PPA is in the public interest.5 In addition, my testimony 18

supports the Company’s proposal that the costs incurred under the solar 19

PPA, together with an additional sum to be determined in this proceeding 20

3 Chicot Solar, LLC is an affiliate of NextEra Energy Resources Acquisitions, LLC, an indirect wholly-owned subsidiary of NextEra Energy Resources, LLC (“NEER”). 4 The Company considers a PPA greater than 5 years to be long-term. 5 Act 1088, new Ark. Code Ann. §23-18-109(c) (1)-(5).

pursuant to Act 1088, would be properly recovered through EAI’s Rate 1

Schedule No. 38, Energy Cost Recovery Rider (“Rider ECR”). 2

In my direct testimony, I: 3

• provide an overview of EAI’s planning processes, including the 4

role of EAI’s RPOC and its President and CEO in that process; 5

• describe the need for renewable resources within EAI’s portfolio 6

of generating resources and some of the benefits of the Project, 7

including the basis for the determination that this solar PPA 8

provides an attractive renewable energy resource to meet those 9

needs; 10

• explain various risks associated with this solar PPA and EAI’s 11

efforts to mitigate those risks; and 12

• explain that, pursuant to Act 1088, EAI is eligible to recover an 13

additional sum as determined in this proceeding and calculated 14

as an equitable sharing of savings between EAI and its retail 15

customers. 16

In addition, I explain that the Company executed an amendment to 17

the Stuttgart Solar, LLC (“Stuttgart Solar”) 20-year PPA on June 19, 2017, 18

with modifications that are beneficial to EAI customers. 19

II. EAI’S RESOURCE PLANNING PROCESS 3

Q. PLEASE DESCRIBE EAI’S RESOURCE PLANNING ACTIVITIES. 4

A. EAI’s Resource Planning and Market Operations team is responsible for 5

identifying and addressing the Company’s resource needs. The core 6

elements of EAI’s resource planning are: 1) a determination of the 7

capability of the Company’s current resources; 2) a forecast of the peak 8

load and energy that the Company expects to serve over the planning 9

horizon; and 3) a determination of the amount of additional resources that 10

will be needed to meet the Company’s load and energy requirements both 11

reliably and cost-effectively. EAI’s planning activities are also conducted 12

consistent with the Commission’s Resource Planning Guidelines for 13

Electric Utilities (“Planning Guidelines”).6 These Planning Guidelines 14

require APSC-jurisdictional utilities to file an IRP at least every three 15

years. Accordingly, EAI’s most recent IRP was filed in 2015 (“2015 IRP”).7 16

EAI’s development of the 2015 IRP focused solely on the needs of EAI 17

and its customers and was 1) developed by EAI’s Resource Planning and 18

Operations Staff, 2) reviewed by EAI’s RPOC, and 3) approved by EAI’s 19

then President and CEO, Hugh T. McDonald. The Company is currently 20

6 Docket No. 06-028-R, Order No. 6, Attachment 1. 7 See, Docket No. 07-016-U, EAI 2015 IRP (October 30, 2015).

in the process of developing its 2018 IRP and expects to file it with the 1

Commission in the 4th quarter of next year. 2

Given the uncertainty inherent in long-term resource planning, 3

EAI’s IRP provides the framework within which the Company will operate 4

over the next few years. The IRP, however, does not serve as a definitive 5

plan for identifying EAI’s long-term generation needs and options for 6

meeting those needs. Rather, the IRP provides a snapshot of current 7

conditions and future expectations, both of which must routinely be 8

reevaluated to account for changing facts and circumstances and to 9

account for any new market opportunities. Nevertheless, EAI’s proposed 10

addition of the Chicot PPA to its portfolio of generation resources remains 11

consistent with EAI’s 2015 IRP Action Plan. 12

13

Q. WHAT ARE THE ROLES OF THE RPOC AND EAI’S PRESIDENT AND 14

CEO IN EAI’S PLANNING PROCESSES? 15

A. The RPOC is an advisory body that provides input and recommendations 16

on EAI planning and operations issues to EAI’s President and CEO. The 17

RPOC conducts meetings, typically each month, that cover a variety of 18

topics affecting the planning and operation of EAI’s generating assets, as 19

well as various MISO transmission planning and market issues. 20

The RPOC has played an integral role in planning and operations 21

activities for EAI, including EAI’s participation in the MISO markets, the 22

development of its annual transmission plan as part of the MISO 23

market solicitations for the acquisition of supply-side and demand-side 4

resources. 5

6

Q. AS PART OF THESE PLANNING ACTIVITIES, HAS EAI EVALUATED 7

LONG-TERM RENEWABLE RESOURCES? 8

A. Yes. EAI evaluated market opportunities to add long-term renewable 9

resources to the Company’s generation portfolio through the 2016 EAI 10

RFP. Issuance of the 2016 EAI RFP was consistent with the action plan 11

in EAI’s 2015 IRP, which indicated that the Company would consider 12

economically-attractive renewable generation, taking into account evolving 13

mandates and an on-going assessment of costs and availability. 14

III. RENEWABLE RESOURCES AS PART OF EAI’S PORTFOLIO AND 1

BENEFITS OF THE SOLAR PROJECT 2

Q. HAS THE GENERAL ASSEMBLY SET FORTH REQUIREMENTS TO 3

CONSIDER IN EVALUATING LONG-TERM PPAS? 4

A. Yes. Act 1088 states that, for a utility to enter into a PPA for more than 5

five years, the Commission must find: 6

(1) The cost of the power purchase agreement is reasonable and 7

prudent; 8

(2) The power purchase agreement will provide savings for retail 9

customers as compared to other generation and power supply 10

options over the term of the power purchase agreement; 11

(3) The power purchase agreement is required by public 12

convenience and necessity; 13

(4) The power purchase agreement is necessary to supplement or 14

replace the utility's existing generation sources; and 15

(5) Approval of the power purchase agreement is in the public 16

interest. 17

While Ms. Fielder and I both discuss a variety of ways that this 18

solar PPA complies with the requirements in Act 1088, including that it is 19

in the public interest, my testimony primarily supports findings 3-5 above, 20

and Ms. Fielder’s testimony primarily supports findings 1-2. 21

Q. WILL THE CHICOT SOLAR PPA HELP MEET THE LONG-TERM NEEDS 1

DESCRIBED IN THE 2015 IRP? 2

A. Yes. The Chicot Solar PPA will help the Company meet the long-term 3

needs of its customers consistent with the Company’s Resource Planning 4

Principles and the 2015 IRP. 5

6

Q. IS THE CHICOT SOLAR PPA AN APPROPRIATE RESOURCE TO 7

SUPPLEMENT EAI’S EXISTING GENERATION IN ORDER TO 8

ADDRESS EAI CUSTOMERS’ LONG-TERM RESOURCE NEEDS? 9

A. Yes. Consistent with the requirements in new Ark. Code Ann. §23-18-10

109(c)(3) through (5), the Chicot Solar PPA adds diversity to EAI’s 11

generation portfolio and is an economically attractive, emission-free 12

resource. It provides EAI with a geographically well-suited resource for 13

meeting its customers’ long-term energy needs and represents another 14

large-scale solar project constructed in Arkansas. In addition, the Project 15

is expected to provide additional societal and economic development 16

benefits. 17

18

Q. PLEASE EXPLAIN HOW THIS RESOURCE WOULD PROVIDE 19

ADDITIONAL DIVERSITY TO EAI’S GENERATION PORTFOLIO. 20

A. Cost and performance parameters for generation technologies differ. 21

Diversity means utilizing a mix of generating technologies and fuel 22

sources within the generation portfolio. A diverse generation portfolio 23

Entergy Arkansas, Inc. Direct Testimony of Kurtis W. Castleberry Docket No. 17-041-U

mitigates risk by helping protect customers from fluctuations in the cost 1

and availability of the fuel needed to produce electricity. For example, a 2

diverse generation portfolio protects customers from supply disruptions 3

associated with particular fuel sources or delivery channels because 4

alternative fuels are available within the portfolio. Similarly, fluctuations in 5

the price of particular fuels are less likely to affect total supply cost. The 6

effect of changes in the price of any one fuel is less significant because a 7

diverse generation portfolio relies on a variety of fuels and resource types, 8

the prices of which are not likely to move in perfect unison. Increases in 9

the price of one fuel may be offset or mitigated by other fuels that exhibit 10

declining or stable costs. 11

In recent years, economic options for increasing diversity have 12

been limited. Among conventional resource alternatives, natural gas-fired 13

combined cycle gas turbine (“CCGT”) and combustion turbine (“CT”) 14

technologies have been the most attractive. Based upon production cost 15

modeling, these highly-efficient technologies are economically attractive 16

across a wide range of fuel and environmental assumptions. New nuclear 17

and advanced coal technologies do provide fuel price stability relative to 18

the price of natural gas that is used to fuel CCGTs and CTs. However, 19

new nuclear and advanced coal technologies are not attractive options 20

relative to natural gas-fired technology because of the current 21

assumptions for the level of required capital expenditures and on-going 22

operating costs, primarily driven by uncertainty around existing and 1

pending environmental and other regulatory requirements. 2

The remaining technology alternatives that can provide such 3

diversity are renewable energy resources. The Chicot Solar PPA offers 4

an opportunity to further diversify EAI’s generation portfolio with the 5

addition of a resource that offers stable pricing while avoiding exposure to 6

volatile fuel prices as well as anticipated CO2 and other environmental 7

emission-based costs. Significantly, the 2016 EAI RFP economic 8

evaluation for the solar PPA indicates that these diversification benefits 9

(the value of which is not included in the economic analysis) can be 10

achieved while lowering customer costs, which also supports the 11

requirement in new Ark. Code Ann. §23-18-109(c)(2) that the PPA provide 12

savings for retail customers as compared to other power supply options 13

over the term of the agreement. 14

15

Q. WOULD YOU EXPLAIN THE SIGNIFICANCE OF AVOIDING 16

EXPOSURE TO POTENTIAL CO2 AND OTHER ENVIRONMENTAL 17

EMISSION-BASED COSTS? 18

A. Yes. As I mentioned above, new nuclear and coal resources provide 19

greater fuel-price stability relative to natural gas resources, given the high 20

variability that natural gas prices have shown over the past two decades. 21

There are, however, future cost uncertainties associated with nuclear and 22

coal resources. For example, the environmental impacts of emissions 23

associated with coal-fired generation and the costs required to address 1

those impacts present issues that will need to be dealt with as additional 2

environmental regulations (e.g., CO2 and other emission regulations), 3

may be imposed upon such facilities. With respect to new nuclear 4

resources, numerous recent examples reflect a host of uncertainties 5

associated with such projects, particularly associated with the cost of 6

construction, raising questions about the viability of such resources in the 7

future. Thus, as EAI’s ANO units approach the end of their license period 8

(which already has been extended by the Nuclear Regulatory 9

Commission), new nuclear resources, with their limited emissions, still 10

may not be a viable option for meeting customers’ future energy needs. 11

The Chicot Solar PPA provides EAI’s portfolio with a generating 12

resource that will not release emissions, will not require significant 13

volumes of water, and will not require pipelines or railways to be 14

constructed to bring fuel to the plant. From an environmental cost risk, as 15

well as an environmental impact standpoint, this solar PPA sourced from 16

the Project has a much lower risk profile than nuclear and coal resources. 17

Entergy Arkansas, Inc. Direct Testimony of Kurtis W. Castleberry Docket No. 17-041-U

A. Yes. Through the 2016 EAI RFP, the Company sought to identify 1

renewable energy proposals that are economically attractive for 2

customers. As discussed by Ms. Fielder and consistent with new Ark. 3

Code Ann. §23-18-109(c)(1) and (2), the solar PPA was the most 4

attractive solar proposal submitted in the 2016 EAI RFP, and EAI’s 5

analysis of that resource indicates that it will provide economic benefits to 6

customers over the term of the PPA. 7

8

Q. DO RENEWABLE ENERGY RESOURCES HAVE BENEFITS BEYOND 9

THE ECONOMIC VALUE TYPICALLY DETERMINED BY PRODUCTION 10

COST MODELING? 11

A. Yes. As set forth in greater detail in EAI’s Application, the Arkansas 12

General Assembly has issued various legislative findings recognizing that 13

the value of renewable energy resources can extend beyond the specific 14

economic value that the resource provides to customers in the form of 15

lower fuel and purchased energy costs.”8 Consequently, the statutes 16

impose an obligation on electric utilities subject to APSC jurisdiction to 17

consider renewable resources as part of their resource plans. This solar 18

PPA is for a renewable resource and is consistent with that obligation. 19

Further, as EAI noted in its action plan in the 2015 IRP regarding 20

renewable resources, “EAI will monitor its load and capability position and 21

8 Ark. Code Ann. § 23-18-701 et.seq. and § 23-18-502 (c)(1).

take steps to add supply-side resources for both traditional and/or 1

renewable resources as warranted.”9 This solar PPA is consistent with 2

this goal. 3

4

Q. WHY IS THE PROJECT’S GEOGRAPHIC LOCATION BENEFICIAL? 5

A. The geographic location of this facility is beneficial because it is physically 6

sited within Arkansas and will be interconnected to the Company’s 7

transmission facilities, making it close to the customers that EAI serves. 8

In addition, its reliance on solar energy enhances this resource’s fit within 9

the Company’s generation portfolio, as a connection can be drawn 10

between the energy needs of EAI’s customers and the energy that this 11

solar PPA will provide. At a high level, customers’ energy needs are 12

highly influenced by the weather, which encompasses the amount of 13

sunlight in the Company’s service territory. The peak energy usage 14

periods arise in the summer months and typically are higher because 15

weather conditions prompt customers to use more energy (e.g., higher air 16

conditioner use). With a resource that generates energy from the same 17

source that is causing those higher loads (i.e., the sun), this solar PPA is 18

expected to provide energy at the times when EAI’s customers’ energy 19

needs are higher, and when one would expect power prices to be higher 20

as well. 21

Entergy Arkansas, Inc. Direct Testimony of Kurtis W. Castleberry Docket No. 17-041-U

In this respect, note that a similar assertion by me in Docket No. 1

15-014-U was addressed by the Attorney General’s witness Kevin 2

Woodruff. His testimony clarified that my statement should not be 3

misinterpreted as a direct correlation between the output of this facility and 4

EAI’s daily peak load.10 To be clear, I do not intend to convey the direct 5

correlation of production and intra-day peak demand that Mr. Woodruff 6

explains. Yet, it is also important to recognize that this solar resource will 7

produce energy in on peak periods, and its location in Arkansas will mean 8

better correlation with EAI’s customers’ energy consumption than a 9

remotely located renewable resource. I also would note that the Chicot 10

facility will utilize solar tracking, which is a technology that Mr. Woodruff 11

previously noted would improve the intra-day production of the resource 12

and presumably mitigate his concerns in this respect. 13

14

Q. WHAT IS YOUR UNDERSTANDING OF THE ECONOMIC 15

DEVELOPMENT BENEFITS THAT THE CHICOT SOLAR PROJECT 16

MAY PROVIDE? 17

A. The Project is designed to qualify for the 30 percent federal investment tax 18

credit (“ITC”) that will be used by the provider to offset its cost of 19

construction. From my conversations with Chicot Solar, I understand that 20

the Project is expected to have a positive economic impact on the local 21

economy. Specifically, Chicot Solar or its affiliate(s) have represented to 1

EAI that they expect to employ approximately 150 to 200 workers during 2

the construction phase; generally, workers and vendors employed by 3

contractors are sourced locally. During the operational life of the project, 4

Chicot Solar expects to expend approximately $600,000 annually in 5

outside services for project site maintenance such as land management 6

and vegetation control, operations office rent, operations team payroll, and 7

other items that will have a local impact. EAI further understands that 8

Chicot Solar estimates that the sales and use tax contributions to the 9

State of Arkansas during the construction phase of the Project will be 10

approximately $1.8 million. I would think it is reasonable to conclude that 11

local businesses such as stores and hotels may also benefit indirectly 12

from the infusion of construction workers and activity during this time 13

period. Further, Chicot Solar has represented to EAI that during the 14

20-year operational life of the Project, it will staff the facility with two to 15

three full-time employees who will be responsible for day-to-day 16

operations and anticipates additional opportunities for local businesses to 17

contract to provide specialized services on-site. In addition, the property 18

taxes during the first year of operation of the Project are estimated to 19

provide approximately $384,000. 20

Entergy Arkansas, Inc. Direct Testimony of Kurtis W. Castleberry Docket No. 17-041-U

A. Yes, I believe it is. As previously mentioned, the General Assembly has 1

found that renewable resources in general are in the public interest.11 In 2

addition to the economic benefits that Ms. Fielder addresses in her 3

testimony, this solar PPA addresses a long-term resource need for EAI’s 4

customers and supplements the Company’s existing generation portfolio 5

by providing locational and fuel diversity benefits and is, therefore, in the 6

public interest. 7

8

IV. RISKS ASSOCIATED WITH THE CHICOT SOLAR PPA 9

Q. ARE THERE RISKS ASSOCIATED WITH THIS AGREEMENT? 10

A. Yes, as there are with any commercial arrangement. As the Commission 11

has recognized previously, there are always risks with respect to resource 12

planning decisions, because the outcomes are always dependent upon 13

future facts and circumstances.12 However, in this instance, the Chicot 14

Solar PPA would be the second long-term PPA that EAI has executed in 15

recent years, and as was the case with the Stuttgart Solar PPA, the 16

manner in which those risks are allocated and borne by the seller on one 17

hand and the Company and its customers on the other must be 18

considered in the evaluation of whether the terms of this solar PPA are in 19

the public interest. 20

Entergy Arkansas, Inc. Direct Testimony of Kurtis W. Castleberry Docket No. 17-041-U

To understand the distinction, first consider a situation where EAI is 1

acquiring a generating facility, such as the Ouachita, Hot Spring, and 2

Union facilities that were acquired relatively recently. In those cases, EAI 3

owns the resources, and consistent with the utility business model, the 4

Company is provided the opportunity to recover its costs of operating and 5

maintaining the unit and earn a fair and reasonable return of and on its 6

capital investments. 7

8

Q. HOW IS THE ARRANGEMENT DIFFERENT WITH THIS SOLAR PPA? 9

A. With this solar PPA, EAI is not earning a return of and on its invested 10

capital commensurate with the prudence relationship I mentioned above 11

with respect to the Company’s owned generating assets. While Act 1088 12

does provide for recovery of an additional sum in the form of a 13

corresponding return on the PPA as would be allowed for an equivalent 14

investment in a power plant, EAI is not seeking an additional sum 15

calculated in that manner for this PPA. In contrast, the contractual 16

obligations of Chicot Solar are established in the contract, including 17

damages for failing to comply with its obligations. EAI’s corresponding 18

rights and obligations (and therefore those of its customers) against Chicot 19

Solar for any failure to perform are as set forth under the contract. 20

Notably, any damages potentially owed by Chicot Solar under the solar 21

PPA may not be based upon the difference between the solar PPA costs 22

and the actual costs incurred for Chicot Solar’s failure to perform its 23

obligations under the contract. Instead, the Company has negotiated the 1

most advantageous contractual terms that it could in order to address 2

such issues. Again, EAI is not seeking recovery of an additional sum in 3

this instance commensurate with the returns it would receive as an owner 4

of the facilities, so it does not bear the same risks for any such potential 5

failures by Chicot Solar to perform as it would with an owned facility. 6

Chicot Solar would be responsible to customers only insofar as the 7

applicable contractual provisions of the solar PPA would require. 8

Ms. Fielder discusses several of the key contractual terms in her direct 9

testimony. 10

11

Q. WHAT ARE THE PRICING OPTIONS ASSOCIATED WITH THE CHICOT 12

SOLAR PPA? 13

A. The specifics regarding the various pricing options available under the 14

Chicot Solar PPA are competitively sensitive. Ms. Fielder addresses the 15

pricing options for Chicot Solar in her direct testimony and Highly 16

V. COST RECOVERY SOUGHT BY EAI FOR CHICOT SOLAR AND 1

ADDITIONAL SUM 2

Q. WHAT COST RECOVERY IS EAI SEEKING FROM THE COMMISSION 3

IN THIS PROCEEDING? 4

A. EAI is seeking approval to recover all costs of the Chicot solar PPA as 5

well as an additional sum in recognition of the unique characteristics of the 6

solar PPA, which is in the public interest. 7

This Chicot solar PPA is a long-term commitment that would be 8

undertaken by EAI for its customers. Given the statutory requirements, as 9

well as the financial obligations associated with the solar PPA that the 10

Company would assume, EAI seeks the Commission’s approval for its 11

decision to enter into this agreement. Indeed, it is for this reason that EAI 12

included a provision in the solar PPA that conditions the agreement on the 13

Commission’s approval, including appropriate cost recovery. 14

15

Q. PLEASE DESCRIBE THE COST RECOVERY PROVIDED BY ACT 1088 16

AND THE COMPANY’S PROPOSAL FOR THIS SOLAR PPA? 17

A. Yes. First, Act 1088 authorizes the Commission to approve recovery of 18

costs over the term of a PPA that it finds to be in the public interest. As 19

discussed, the facts of this case support that this solar PPA is in the public 20

interest and, therefore, EAI should be permitted to recover the costs of the 21

PPA over the term of the agreement. 22

Entergy Arkansas, Inc. Direct Testimony of Kurtis W. Castleberry Docket No. 17-041-U

Second, Act 1088 authorizes the Commission to provide a utility 1

recovery of an additional sum recognizing the unique characteristics of a 2

PPA and the benefits that arise from such an agreement if the 3

Commission finds that the additional sum is in the public interest. In 4

determining the additional sum, Act 1088 provides that the Commission 5

may consider an equitable sharing of savings between the utility and 6

customers, with customers receiving no less than 75 percent of any 7

savings. 8

9

Q. IS EAI REQUESTING THAT THE COMMISSION ALLOW IT TO 10

RECOVER SUCH AN ADDITIONAL SUM? 11

A. Yes. Should the Commission approve the solar PPA, EAI requests that 12

the Commission also approve recovery of an additional sum representing 13

an equitable sharing of the savings with customers. By entering into this 14

solar PPA, EAI is taking steps to provide customers with an attractively 15

priced, emission-free renewable energy resource that offers a variety of 16

economic and environmental benefits, including bringing another 17

large-scale solar project to the State of Arkansas as I mentioned 18

previously, and doing so at a time to provide EAI’s customers the benefits 19

of current federal investment tax credits available for such solar resources. 20

interest, but it will encourage the further pursuit of transactions of this type, 2

A. EAI proposes to calculate the additional sum for this solar PPA based on 7

an equitable sharing of savings with customers consistent with Act 1088. 8

Consistent with the Commission’s decision on the Stuttgart PPA, EAI 9

would propose to calculate the actual savings associated with the Chicot 10

Solar PPA using the methodology that originally was proposed by the 11

Staff, agreed to by EAI, and ultimately approved by the Commission for 12

Stuttgart. In this case, however, EAI would propose that customers 13

receive 75 percent of the savings and the Company receive 25 percent of 14

the savings, an outcome that is consistent with the Commission’s authority 15

under Act 1088 and, EAI believes, is warranted in this case. 16

Entergy Arkansas, Inc. Direct Testimony of Kurtis W. Castleberry Docket No. 17-041-U

A. In my opinion, each PPA transaction should be evaluated on its own 1

merits, depending on its specific facts and circumstances. In this case, 2

the facts and circumstances presented for the Chicot Solar PPA merit the 3

highest award of sharing allowed for EAI under Act 1088. My opinion is 4

based upon several factors associated with EAI’s efforts in this 5

proceeding, all of which I have mentioned above, but which I will 6

summarize here. 7

With the Chicot Solar PPA, EAI has once again negotiated and 8

executed a PPA for a very valuable renewable resource for its customers 9

on what I believe are very favorable terms, with the benefits of this 10

resource projected to exceed the benefits of the Stuttgart PPA 11

substantially. As explained by Ms. Fielder, the proposed solar PPA has a 12

projected 2017 net present value (“NPV”) savings of approximately $91.4 13

million in the reference case production cost scenario over the term of the 14

agreement, and that figure is based upon the highest priced option 15

available to EAI. In that respect, the development of the pricing options 16

available under the Chicot Solar PPA reflects an innovative approach to 17

structuring such a proposal, as Ms. Fielder discusses in more detail in 18

Highly Sensitive EAI Direct Exhibit KF-3. In addition, EAI has also 19

executed an amendment to the Stuttgart Solar PPA that provides 20

additional benefits to EAI’s customers, as I will discuss later in my 21

testimony and in Highly Sensitive EAI Direct Exhibit KWC-1. 22

Entergy Arkansas, Inc. Direct Testimony of Kurtis W. Castleberry Docket No. 17-041-U

In Order No. 5, in Docket No. 15-014-U, the Commission 1

recognized that the evidence shows that the sharing of actual net benefits 2

will result in EAI receiving less than if it received a commensurate return 3

on an equivalent investment in a power plant.14 In my opinion, the 4

Commission should incent utilities not only to seek out resources such as 5

these through competitive solicitations, but also to strive for innovative 6

approaches and solutions in those cases that ultimately inure to the 7

benefit of customers. EAI has done so in connection with the Chicot Solar 8

PPA and the amendment to the Stuttgart Solar PPA. Its actions and 9

efforts merit the Commission rewarding it to the fullest extent possible 10

allowed by Act 1088. The Commission recognized the importance of the 11

additional sum in Order No. 5 by stating 12

“Through this mechanism the utility is incentivized to 13 seek and negotiate favorable agreements with the 14 lowest possible PPA price and the highest actual 15 benefits.”15 16

Consistent with the Commission’s stated desire to incent a utility to 17

negotiate for the lowest possible PPA price and the highest actual 18

benefits, EAI should receive the highest possible additional sum. Absent 19

such action in this case, I believe the utilities in Arkansas will be left to 20

wonder whether any circumstances would merit the full award 21

contemplated by the Arkansas Legislature in enacting Act 1088. 22

Q. HOW DOES EAI PROPOSE TO RECOVER THE ADDITIONAL SUM? 2

A. After receiving the Commission’s approval of the additional sum in this 3

additional sum through Rider ECR. Mr. Celino provides an overview of 5

the existing provision of Rider ECR, approved in Docket No. 15-014-U,16 6
