The Regional Transmission Plan addresses regional and ERCOT-wide reliability and economic transmission needs and the planned improvements to meet those needs for the planning horizon (up to six years). Proposed transmission projects are categorized into Reliability driven and Economic driven Projects. The differentiation between these two types of projects is based on whether a simultaneously-feasible, security-constrained generating unit commitment dispatch is expected to be available for all hours of the planning horizon that can resolve the system reliability issue that the proposed transmission project is intended to resolve. If it is not possible to simulate a dispatch of the Generation Resources such that all reliability criteria are met without the project, and the addition of the project allows the reliability criteria to be met, then the project is classified as a reliability-driven project. If it is possible to simulate a dispatch of the Generation Resources in such a way that all reliability criteria are met without the project, but the project may allow the reliability criteria to be met at a lower total cost, then the project is classified as an economic-driven project. For reliability-driven projects, the comparison of project costs generally includes only the relative capital costs of the alternatives. DNV staff selected and proposed for this engagement have also, since 2008, directly participated in the ERCOT RPG process on behalf of the ERCOT TSP’s for various reliability transmission driven projects. DNV has conducted various reliability studies in ERCOT to identify the best solution and to determine the cost vs benefit. The contribution of DNV includes screening analysis to identify potential reliability issues beforehand in the area of interest, and if needed perform a detailed transmission system analysis to validate issues identified in the screening analysis. If a reliability concern is identified, DNV will identify transmission solutions to meet ERCOT reliability or economic criteria. DNV will outline the study assumptions, methodology, transmission base case(s) analysis, planning horizon scenarios to be studied, identifying transmission alternatives, coming up with criteria matrix to identify relative performance of the transmission alternatives, propose and recommend the best alternative(s), conduct sensitivity analysis as needed to validate the long-term benefits of the proposed solution. The above detailed approach aids the TSP in making the decision if the transmission solution is advantageous in relative performance by meeting all of the ERCOT reliability criteria. DNV has conducted various detailed technical system analysis such as steady state load flow and contingency analysis, short circuit breaker adequacy analysis, transient or dynamic stability analysis, and system strength assessments such as short circuit ratio and sub synchronous resonance assessments. The analysis will consider system normal operation, NERC Category contingencies including ERCOT Category contingencies and any additional contingency conditions ERCOT might be interested in evaluating. DNV will also utilize the results of the annual system planning and FERC 715 filing study to evaluate the need for transmission system enhancements and/or new projects on the DME and/or neighboring transmission system. DNV will work with DME and other interconnected utilities to develop justification for the projects based on the ERCOT reliability criteria. DNV will also review the studies performed by neighboring utilities to ensure optimal system benefits from a DME standpoint and adequate justification for reliability projects. 6.3 Transmission project submission to ERCOT for Regional Planning Group (RPG) review, comments and approval Depending on the Tier (1, 2, 3, 4) of transmission projects, except projects that have only localized impacts and projects that are directly associated with the interconnection of new Resources, all other transmission projects in the ERCOT Docusign Envelope ID: 185AFDF7-340D-84E7-816C-AB43765F33D1 DNV Doc.

Timestamps Electronic Record and Signature Disclosure ELECTRONIC RECORD AND SIGNATURE DISCLOSURE From time to time, City of Denton (we, us or Company) may be required by law to provide to you certain written notices or disclosures. Described below are the terms and conditions for providing to you such notices and disclosures electronically through your DocuSign, Inc. (DocuSign) Express user account. Please read the information below carefully and thoroughly, and if you can access this information electronically to your satisfaction and agree to these terms and conditions, please confirm your agreement by clicking the 'I agree' button at the bottom of this document. Getting paper copies At any time, you may request from us a paper copy of any record provided or made available electronically to you by us. For such copies, as long as you are an authorized user of the DocuSign system you will have the ability to download and print any documents we send to you through your DocuSign user account for a limited period of time (usually 30 days) after such documents are first sent to you. After such time, if you wish for us to send you paper copies of any such documents from our office to you, you will be charged a $0.00 per-page fee. You may request delivery of such paper copies from us by following the procedure described below. Withdrawing your consent If you decide to receive notices and disclosures from us electronically, you may at any time change your mind and tell us that thereafter you want to receive required notices and disclosures only in paper format. How you must inform us of your decision to receive future notices and disclosure in paper format and withdraw your consent to receive notices and disclosures electronically is described below. Consequences of changing your mind If you elect to receive required notices and disclosures only in paper format, it will slow the speed at which we can complete certain steps in transactions with you and delivering services to you because we will need first to send the required notices or disclosures to you in paper format, and then wait until we receive back from you your acknowledgment of your receipt of such paper notices or disclosures. To indicate to us that you are changing your mind, you must withdraw your consent using the DocuSign 'Withdraw Consent' form on the signing page of your DocuSign account. This will indicate to us that you have withdrawn your consent to receive required notices and disclosures electronically from us and you will no longer be able to use your DocuSign Express user account to receive required notices and consents electronically from us or to sign electronically documents from us. All notices and disclosures will be sent to you electronically Unless you tell us otherwise in accordance with the procedures described herein, we will provide electronically to you through your DocuSign user account all required notices, disclosures, authorizations, acknowledgements, and other documents that are required to be provided or made available to you during the course of our relationship with you. To reduce the chance of you inadvertently not receiving any notice or disclosure, we prefer to provide all of the required notices and disclosures to you by the same method and to the same address that you have given us. Thus, you can receive all the disclosures and notices electronically or in paper format through the paper mail delivery system. If you do not agree with this process, please let us know as described below. Please also see the paragraph immediately above that describes the consequences of your electing not to receive delivery of the notices and disclosures electronically from us.
