November 8, 2017 ELECTRONICALLY FILED WITH RCA Regulatory Commission of Alaska 701 W. 8th Avenue, Suite 300 Anchorage, Alaska 99501 Subject: Tariff Advice No. 446-8; Second Amendment to the Isolated Operating

Agreement for Government-Owned Disaster Preparedness Generation Facilities between Chugach Electric Association, Inc. and the Anchorage School District

Commissioners: The tariff filing described below is hereby transmitted to you for filing in compliance with the Alaska Public Utilities Regulatory Act and Sections 3 AAC 48.200 - 3 AAC 48.420 of the Alaska Administrative Code. With this filing, Chugach Electric Association, Inc. (“Chugach”) requests approval of the attached agreement entitled, “Second Amendment to the Isolated Operating Agreement for Government-Owned Disaster Preparedness Generation Facilities between Chugach Electric Association, Inc. and the Anchorage School District” (“Second Amendment”). Tariff Sheet No. 73 of Chugach’s operating tariff is attached and has been updated to reflect the Second Amendment. TARIFF SHEET NUMBER CANCELS SHEET NUMBER SCHEDULE OR ORIGINAL REVISED ORIGINAL REVISED RULE NUMBER

73 14th Revision 73 13th Revision Schedule of Special Contracts This filing is not for a new service, will not result in the termination of an existing service, conflict with any other schedule or rate contained in Chugach’s operating tariff, or in any other way adversely impact customers or the public. This filing has no impact on Chugach’s revenues, and Chugach does not believe that any individual customer is directly impacted by this filing. Rather, Chugach believes the interconnected electric power system is benefitted by the limited power supply redundancy permitted by the Second Amendment. Thus, the Second Amendment does not adversely affect other customers and there is no impact on Chugach’s rates or charges. Chugach has approximately 67,800 retail members (80,900 retail metered locations). This filing has no impact on wholesale members. Summary The Anchorage School District (“ASD”) installed generation facilities at various schools located throughout the Municipality of Anchorage as part of a district-wide disaster preparedness effort to provide shelter for students, faculty and in some instances the community during disaster and emergency situations. As part of this effort, ASD installed a generator within the Service High School Complex (“School Complex”) and requested that it be permitted to use Chugach’s distribution system within the complex when power from Chugach’s interconnected grid is not available. Chugach agreed to allow the ASD use of its distribution system facilities within the

Commissioners November 8, 2017 Tariff Advice No. 446-8 Page 2 of 4

School Complex without any attendant wheeling or other access charges provided the power is wheeled in response to an emergency situation or for testing purposes in conformance with the guidelines contained in the agreement. In 2006, Chugach and the ASD entered into an agreement titled, “Isolated Operating Agreement for Government-Owned Disaster Preparedness Generation Facilities” (“2006 Agreement”). This Agreement specified the terms and conditions under which ASD may use Chugach’s distribution facilities within the School Complex for the delivery of emergency power from ASD’s generator during times when power from Chugach’s interconnected grid was not available. Under terms of the 2006 Agreement, the ASD is not permitted to generate power for delivery outside the School Complex unless otherwise authorized by Chugach. In no event shall electricity generated by ASD be resold or be delivered to locations that are not used or relied upon by ASD in response to an emergency situation. The 2006 Agreement was submitted to the Commission under Tariff Advice No. 275-8 and approved in Letter Order L0600565. The Agreement was for a ten-year term ending December 31, 2016. On February 13, 2017, the Commission approved a 1-year extension of this Agreement in Tariff Advice No. 432-8.1 Contract Summary The 2006 Agreement has worked very well over the past eleven years and the Parties have not experienced any significant difficulties with the 2006 Agreement. The Second Amendment updates the 2006 Agreement in two fundamental ways: 1) commissioning and testing protocols associated with the original commissioning of the generation unit have been removed; and, 2) switching responsibilities have been transferred from the ASD to Chugach. Below is a summary of each section of the Second Amendment. Section 1: Parties, identifies the parties to this agreement. Section 2: Recitals, describes the parties, including the need for, and conditions of, the operating agreement for disaster preparedness generation service. This Section has been expanded to include reference to the 2006 Agreement and the one-year extension. Minor wording changes have been made for increased clarity. Section 3: General, articulates the key provisions of this Agreement. This Section is largely unchanged from the 2006 Agreement with the exception of updates to Sections referenced in the Agreement. It describes the terms under which the ASD will use the Chugach Distribution facilities within the School Complex and prohibits the ASD from reselling or delivering energy generated by ASD for purposes other than emergency situations. The ASD is also prohibited from delivering generated energy to those outside the School Complex area, including into the Chugach supply grid. 1 See Letter Order L1700050.


Section 4: Ownership of and Responsibility for Equipment, specifies which party will own, maintain and be responsible for which equipment. It also describes the process to be followed if replacement, modification or design of the ASD equipment is contemplated. Section 5: Operational Conditions and Procedures, contains descriptions of the situations when the standby generation will be utilized and the rights of the parties in those situations. In the 2006 Agreement, Section No. 5 addressed initial systems testing and acceptance provisions. Because the emergency generator is now installed and operating, that Section has been deleted in its entirety. The new Section 5 addresses operational conditions and procedures and remains largely unchanged from the 2006 Agreement. This Section references Attachment A to the Second Amendment to describe the conditions under which the emergency generator will be operated. It also covers the conditions for generator testing, limits and coordination efforts required for such testing. It permits Chugach to disconnect the generator from the Chugach system, when necessary, to protect personnel or property. Section 6: Metering, Rates and Billing, specifies how energy supplied by the parties will be identified and treated with this type of arrangement. The description of several delivery points has been updated. Chugach has redacted member and account numbers from this Section of the attachment as they are considered confidential member information. The parties deleted the provision regarding telecommunication access for the delivery points. This is no longer needed because meter reading is now completed through Chugach’s Advanced Metering Infrastructure program. Section 7: Term; Transferability; Amendments; Termination, identifies when this Agreement becomes effective, its duration and how it would be terminated. Similar to the 2006 Agreement, the parties again seek a ten-year term, through December 31, 2027, for the Second Amendment. Section 8: Miscellaneous Provisions, provides the Second Amendment is subject to RCA approval and remains subject to revision by the RCA. Section 8 also contains boilerplate contractual provisions covering indemnification, waivers, no third-party beneficiaries, governing law, severability, insurance and notice provisions, all of which are identical to the 2006 Agreement. Section 9: Definitions, provides explanation of the terms used in the Agreement. Changes in this Section are clarifying in nature. Tariff Sheet Changes Tariff Sheet No. 73: The text “Second Amendment to the” has been added to the beginning of the sentence on item number “2.” simply to acknowledge that this is the second amendment to this contract. In addition, the effective date has been changed from “September 1, 2006 through December 31, 2017” to “January 1, 2018 through December 31, 2027” to reflect the new term of the Second Amendment.

Tariff until this Agreement is approved by the RCA and, notwithstanding

anything to the contrary contained herein, this Agreement is at all times

subject to revision by the Commission.

33. Representations and Warranties

Each individual signing this Agreement represents that he/she is duly

authorized to execute this Agreement on behalf of the Party for whom he/she

is signing and that upon his/her execution hereof the Party for whom he/she is

signing will become legally and validly bound to this Agreement.

34. Indemnification

Each Party shall, as to all actions taken relevant to this Agreement, indemnify

and hold harmless the other Party, its directors, officers and employees,

against all costs, loss, damage, legal expense and liability to third persons

arising from any injury to, or death of, persons or injury to property to the

extent caused by any act or omission of the indemnifying Party, or its

directors, officers, agents, or employees. Except to the extent prohibited by

law, ASD shall, at all times during the term of this Agreement, indemnify,

defend, and hold harmless Chugach and its directors, officers, employees, and

agents from and against any and all claims, demands, actions, causes of

action, damages, or losses of third parties arising out of, or resulting in any act

or omission of ASD, including but not limited to any claims, demands,

actions, causes of action, damages or losses, including property damages,

personal injury or death, for any power delivered to parties by ASD during


emergency or testing situations via the Generator, including but not limited to

power delivered by ASD to AWWU and the MOA, at Delivery Points within

the Service High School Complex hereunder.

35. No Waiver or Estoppel

The failure of a Party to insist on the strict performance of any provision of

this Agreement or to exercise any right, power, or remedy upon a breach

thereof shall not constitute a waiver of the same or of any other provision of

this Agreement, and shall not estop the Party from enforcing said provision or

any other provision of this Agreement or from exercising any right, power, or

remedy upon the breach or any other breach of this Agreement.

36. No Third Party Beneficiaries

The Parties hereby agree that by entering into this Agreement neither Party

has created any obligation for the benefit of any third party, promised any

performance to any third party, or otherwise created or vested in any third

party a right to enforce all or any portion of this Agreement.

37. Governing Law

This Agreement shall be interpreted, construed, and enforced in accordance

with, and otherwise governed in all respects by, the laws of the State of

Alaska, with venue being appropriate in Anchorage.

38. Severability

The provisions of this Agreement are not intended to be considered in

isolation. Each provision represents a portion of the consideration agreed

upon among the Parties for each other provision of this Agreement. The

Parties believe that it would be impossible, in general, to invalidate or sever


any particular provision of this Agreement without working a potentially great

hardship on one or the other of the Parties, and without denying one or both of

the Parties of important, bargained for consideration. Thus, if after this

Agreement has become effective, any provision of this Agreement shall be

finally adjudicated by any court or government agency with jurisdiction over

the subject matter to be invalid or unenforceable, or if any government agency

with authority over the Parties requires changes to this Agreement then either

Party may terminate this Agreement pursuant to Section 7. If, however,

neither Party terminates this Agreement pursuant to Section 7, any provision

found to be invalid or unenforceable shall be deemed to be severed from this

Agreement and any changes required to be made to this Agreement shall be

deemed made, and this Agreement as so modified shall continue in effect.

39. Insurance

Each Party agrees to obtain and maintain in full force and effect during the

term of this Agreement, adequate insurance (or an equivalent self-insurance

program) with responsible insurers as may be required by law and as are

appropriate to the operations contemplated herein.

Attachment A:

Power Emergency Sequence of Operations for

Service High School Disaster Preparedness Generator

Automatic Source Transfer Sequence from Chugach to ASD Generator:

1. Upon loss of Chugach source potential on all three phases, sensed at Chugach’s SC

839 Way-1, switch 14090, the Chugach control relay will initiate a 3-minute

delayed trip at SC 839 Way-1. Simultaneously the ASD generator transfer control

will initiate a 5-minute delay to allow for recovery of Chugach source potential.

2. After 3-minutes, if Chugach source potential is not restored on all three phases at

SC 839 Way-1, switch 14090, the Chugach control relay will automatically open

SC 839 Way-1.

3. After 5-minutes, if Chugach source potential is not restored on all three phases at

SC 839 Way-1, the ASD controller will start the ASD generator.

4. After the generator is running and the ASD transfer control has verified that SC

839 Way-1, switch 14090 is in the open position (all three-phases) the ASD

transfer control will send a close signal to SC 839 Way-2 switch 14091 completing

the transfer sequence from Chugach source to the ASD generator.

Manual Source Transfer Sequence to Restore Chugach Supply:

1. Upon restoration of Chugach source potential on all three phases, at SC 839 Way-

1, switch 14090, Chugach dispatch will receive indication that system voltage is

normal. The ASD transfer control will illuminate three lights within the ASD

generator control cabinet (indicating that Chugach source potential is available).

The ASD generator will provide power until communication can be established

between the local ASD personnel and Chugach dispatch for a controlled transfer to

return to Chugach power.

2. Under normal operating protocol Chugach dispatch will contact ASD using the

ASD provided contact information. When communication is established the

voltage on all three phases at SC 839 Way-1, switch 14090 will be verified and

Chugach dispatch will assess whether to transfer back remotely from dispatch or

locally utilizing Chugach line personnel.

3. The controlled transfer sequence is to open SC 839 Way-2, switch 14091 and close

Way-1 switch 14090 to restore the Chugach source power. The generator will

continue to run and voltage may be present at SC 839 Way 2 until the generator

has completed the 10-minute shutdown period.
