1 SCE Grid Interconnection Workshop
Introduction to SCE’s Generator Interconnection Processes with Guidance to Select the Appropriate Path to Interconnection SCE Grid Interconnection Workshop

2 SCE Grid Interconnection Workshop
Objectives The purpose of this presentation is to: Provide answers to basic interconnection-related questions to prospective generation project* developers Identify the options to interconnect depending on the ultimate use/purpose of the energy produced Guide interconnection customers to the selection of the appropriate interconnection process * In this presentation, the word “project” refers to a generation or energy storage facility (and the assets associated with it) that is intending to be interconnected to SCE’s electric system. SCE Grid Interconnection Workshop

3 Frequently Asked Questions Regarding the Interconnection Process
What generation equipment should I use? Who will buy my project’s output? Where should I locate my project? ? ? ? How much will my interconnection cost? ? How long will it take? ? ? How do I participate in the CAISO market?

4 What Generation Equipment?
SCE does not design your generation or storage facility. The developer chooses the type of technology and technical specifications for the project If the generation owner plans to sell the energy under a specific energy procurement program, there might be requirements (such as size, technology, technical specifications, etc.) to participate in the program. Consult the entity you are selling your energy to. Once you have designed your project and decided to interconnect to SCE’s system, a complete application is required to commence the interconnection process. The application includes: complete detailed technical data regarding the equipment chosen including balance of plant items (e.g., inverters, power system controls, etc.) a site plan, a single-line diagram, demonstration of exclusive rights to use the proposed site, and the applicable review fee or study deposit SCE Grid Interconnection Workshop

5 Where Should I Locate my Project?
In general, SCE does not provide recommendations on the project’s location Some of SCE’s energy procurement programs may be targeted for projects located in specific, preferred areas. Consult SCE’s Power Procurement team However, where you locate your facility is important in the interconnection process The interconnection process varies depending on whether the proposed project connects to SCE’s transmission or distribution lines System constraints, such as areas of over-generation, may impact the cost and timing of your interconnection Choosing the right size and location could expedite the interconnection process SCE maps of its distribution circuits provide information that could help developers to size or site a project SCE’s Interconnection Circuit Maps (DERiM) SCE Grid Interconnection Workshop

6 SCE Grid Interconnection Workshop
What System Information Is Available to Make Decisions about My Project? At any time, any interested party can request technical information regarding SCE’s electric system around a potential interconnection site. Upon receipt of a completed Pre-Application Report Request and a non-refundable processing fee of $300, SCE will provide available system data. This typically includes: Total Capacity (in MWs) of substation bus Approximate circuit distance between the proposed site and the substation Relevant line section(s) peak line load estimate Number of protective devices and voltage regulating devices between the proposed site and the substation/area Whether or not three-phase power is available at the site Limiting conductor rating from proposed Point of Interconnection to distribution substation Links for more information about how to request a Pre-Application Report: Pre-Application Report Request <link # 9a> under SCE’s WDAT Pre-Application Report Request <link # 9b> under SCE’s Rule 21 SCE Grid Interconnection Workshop

7 Who Will Buy My Project’s Output?
Largely depends on who is your intended market: Wholesale market Sales to SCE, CAISO or any other 3rd party under a wholesale contract. It usually requires Seller to become a participant in CAISO’s market. Sell 100% to SCE under a Power Purchase Agreement For more information about the available SCE energy procurement programs, refer to SCE’s Power Procurement website at Self-Generation These are projects built on site for use by, or sale directly to, an energy customer without exporting power for sale into SCE’s system Self-Generation (and Billing Credits) These are projects built on site for use by, or sale directly to, an energy customer that may export excess power to SCE’s system in exchange for “billing credits”. Existing SCE programs that offer billing credits include Net Energy Metering (NEM) and RES-BCT (more on this later) SCE Grid Interconnection Workshop

8 How Do I Participate in the CAISO Market?
CAISO provides information on how to become a market participant at The interconnection process applicable for a project that is intending to be a CAISO’s market participant depends on whether the project interconnects to the transmission or distribution system Refer to CAISO’s “Resource Interconnection Guide” website if your project is connecting to the transmission system Refer to SCE’s [WDAT Page] if your project is interconnecting to SCE’s distribution system Any new project participating in CAISO’s market is required to follow CAISO’s New Resource Implementation (NRI) process SCE encourages developers to become familiar with the NRI process since CAISO requires notice at least 210 days prior to online date. SCE Grid Interconnection Workshop

9 How Much Will it Cost, And How Long Will it Take?
The cost and time to interconnect is determined when the project is evaluated or studied through the applicable interconnection process The next sections of this presentation will provide more details about the available interconnection processes. For each process, we will describe: What tracks are available to evaluate the proposed project and to identify its interconnection requirements (scope, cost, and timing) The timelines for the various tracks, including study timelines, security postings, and negotiation of interconnection agreements How interconnection costs are determined and how financial responsibility is allocated SCE Grid Interconnection Workshop

How to Identify the “Right” Interconnection Process Based on the Use/Purpose of the Energy Produced SCE Grid Interconnection Workshop

11 Most Common System Configurations
Backup Systems Used by Customers to serve part or all of their electrical needs during a power outage. They are normally operated only when SCE’s electric service is not available. Self-Generation Systems Used by Customers to produce electricity using equipment they (or a third party) own and operate at their site to meet some or all of their energy needs (thus reducing energy use from SCE). Systems for Power Sales Projects that interconnect to SCE’s grid with the intent to sell power will have the option of selling energy and capacity products directly to SCE, CAISO, or any 3rd party in the open market. SCE Grid Interconnection Workshop

12 Interconnecting Your Backup System
These systems operate under either one of two modes: Momentary Parallel mode A backup generator that interconnects and operates with SCE’s Distribution System for duration of one (1) second or less through transfer switches or operating schemes specifically designed and engineered for such operation Isolated mode A backup generator that will be isolated and prevented from becoming interconnected with SCE’s Distribution System through a transfer switch or operating scheme specifically designed and engineered for such operation For either one of this systems, the customer must submit a Rule 21“Non-Exporting” Interconnection Request [link]. Refer to SCE’s [backup] webpage for additional information and for complete application requirements SCE Grid Interconnection Workshop

13 Backup Systems What to Expect in the Interconnection Process
Following the submittal of the application package and applicable fee, an assigned engineer will review the technical data provided (usually within ten (10) business days) Once the application package is approved, you will be required to demonstrate (via a commissioning test) that your generator complies with Rule 21 Tariff requirements for backup operation (usually within 15 business days or as otherwise agreed) Once all of the technical reviews, and inspections are completed you will receive a notification authorizing the operation of your back up system (usually within 10 business days of completion) Additional Information: Please consult with your local permitting authority to verify any local permitting requirements. SCE does not provide permitting services. SCE Grid Interconnection Workshop

14 Self-Generation Systems - Intro
A self-generator uses electricity from a system on site to meet some or all of its energy needs. These systems operate in parallel to SCE’s electrical system. The following are billing programs that helps you take advantage of being a self-generator: Net-Energy Metering (NEM) Self-generators who have eligible renewable energy generation systems connected to SCE and meet program requirements can apply for a rate billing option called Net Energy Metering (NEM). The NEM option allows you to receive a billing credit for the surplus electricity delivered to SCE’s electric grid. This credit will then be applied to your account to offset part of energy charges on your electric bill. Please visit the following link to learn more about this program: Renewable Energy Self-Generation Bill Credit Transfer (RES-BCT) Eligible local governments or campuses that own or operate a qualifying renewable energy generating facility located on their property can apply for RES-BCT. It allows the customer to apply credits for the surplus electricity delivered to SCE’s electric gird to other eligible “benefiting accounts” also owned by the customer. Please visit the following link to learn more about this program: SCE Grid Interconnection Workshop

15 Interconnecting Self-Generation Systems
The interconnection process for Self-Generation Systems depends on the program intended: Net-Energy Metering (NEM) Application for Interconnection: Rule 21 Application Form [link] Application Interconnection Fees: none Interconnection Process: Before you can operate your system, you are required to obtain a “permission to operate” letter from SCE. SCE typically issues this letter within thirty (30) business days after the following requirements are met: (1) SCE’s acceptance of a complete NEM Application packet, (2) execution of the appropriate interconnection and generation agreements, and (3) final electrical inspection. For more Information about NEM, please visit Renewable Energy Self-Generation Bill Credit Transfer (RES-BCT) Application for Interconnection: Interconnection of a RESBCT system to SCE’s electric grid requires a Rule 21 Export Application Form [link] Application Interconnection Fees: Depends on applicable track [link] Interconnection Process: Depends on applicable track [link] For more information about RES-BCT, please visit SCE Grid Interconnection Workshop

16 Systems for Power Sales - Intro
Generation projects that interconnect to SCE’s grid with intent to sell power operate in parallel with SCE’s electric system. Please make note of the following: In most instances the entity that you intend to sell power to will identify requirements that may affect the interconnection process (such as the size of the project, the expected online date, the desired technology, etc.). The interconnection process you select should satisfy the Power Purchase Agreement (PPA) you decide to pursue. Review the terms of the PPA carefully to ensure you apply for the appropriate interconnection agreement. The energy sales under the PPA you pursue will be governed by either the CPUC or FERC. This means that the PPA may require you to choose between the CPUC or FERC jurisdictional interconnection process. SCE Grid Interconnection Workshop
