ISO New England provides this web guide to help you understand the interconnection process for small and large generating stations and optional transmission upgrades (ETUs) for connection to the managed transmission network. However, you shouldn`t just rely on this web guide. Consult ISO New England Inc. Transmission, Markets, and Services Tariff (ISO Tariff), Section II, known as ISO`s Open Access Transmission Tariff (OATT), along with relevant planning and operating procedures to ensure you meet all requirements. In the event of a discrepancy with this web guide, the ISO tariff and the applicable operating and planning procedures shall apply. Although small generators cannot ask for E&P, they do have another option – see the facility study information for more information. Use the diagram in this section to assess whether the sign-in process applies to your project. If you are unsure, please contact the circuit owner and ISO to determine if the installation is part of the managed system for connection purposes. In addition to submitting your interconnection application before starting business operations, you must also register as a market participant in order to participate in individual ISO markets and ancillary services. Instructions and options can be found on the participant registration website. All technical data are due at the time of submission of the interconnection request. Appendix 23, Appendix 2 and Appendix A of the IR form provide details on the data required. To opt for accelerated interconnection, inform ISO in writing within 10 working days of the results of your System Impact Assessment (SIS).
The associated timelines are as follows: The IR must be submitted to ISO through the IRTT, a web application for submitting, tracking and viewing connection requests. For an IR to be considered valid, it must: Several annexes to ISO`s open access tariff contain rules that detail the interconnection process: Once a resource has signed an interconnection agreement and becomes commercial, it can participate in all New England markets. Clients participating in ISO-managed markets must register their assets with ISO New England for settlement and other market-related purposes. Other types of generators may also be required to provide an acceptable simulation model, as discussed at the framework meeting. Before sending an interconnection request (IR) to ISO to connect a new generating station or optional transmission upgrade (ETU) or modify an existing facility, you must determine whether your project will be connected to the ISO-managed transmission system as part of the ISO process or will be connected through the state process. A generating station participating in wholesale electricity markets that were originally interconnected as part of a government process must follow the ISO interconnection process for any changes. The “Interconnection Process” training is available on the website along with the training materials. Annex 22, Section 11, Standard Large Producer Interconnection Agreement (LGIA), includes the process for developing the Large Producer Interconnection Agreement; Annex 25 contains those relating to optional transport upgrade interconnection agreements (ETUIA); and Annex 23, Section 4.8, IAMS (Small Producer Interconnection Agreement), includes those for small producers. The following is a summary of the most important points. Once ISO has validated your interconnection request, it assigns a queue position to your project in the ISO interconnection queue to determine upgrades and cost responsibility, as well as the order in which ISO should perform interconnection studies. A project scoping meeting will review relevant information about your project and the liaison studies that ISO is conducting to assess the impact of your project on the energy system and the facilities and upgrades that may be required to connect your project in accordance with all requirements and standards.
Follow the ISO connection process in this guide. Getting Started → For more information on future projections for projects like these, see the Distributed Generation Forecasts or Demand Resources Working Group reports. Projects listed in the non-FERC affected jurisdiction/system portion of the queue can also be listed in connection queues managed by distribution companies or adjacent control areas. Among other things, the queue data represents the potential future combination of electricity resources in New England, as outlined in tomorrow`s energy mix and reported in iso`s Chief Operating Officer`s monthly reports to the participants` committee. However, the queue is a dynamic database that can change from day to day as projects send or remove connection requests or start operations. Stakeholders and media professionals trying to export and interpret the latest queue data should consider the following important points: To speed up the connection of a large generator or optional transmission upgrade, you can request an engineering and provisioning agreement from the owner of the connection transmission. This is done before the execution of an interconnection agreement and gives you the opportunity to do without the facility study (AEC). Accelerated connection commits you to one or more of the following steps under the LGIA (Appendix 22): Once you have determined that you intend to establish a resource that must connect to the managed transmission system, refer to the Interconnection Process Guide for the necessary details and other connection steps. Applications should be sent to the Interconnection Request Tracking Tool (IRTT). ISO`s Open Access Transmission Tariff (OATT) describes the rules of the interconnection process.
See Annex 22, Section 9, Engineering and Supply Agreement for Large Generators or Appendix 25 for ETUs. As a regional transmission organization (RTO), ISO coordinates how transmission lines, power plants and other resources are connected and operated in New England`s managed transmission system to ensure reliability and facilitate participation in the wholesale electricity market. ISO does not manage the interconnection process for projects subject to government interconnection processes. Thus, after determining that the ISO interconnection process applies to your project, you must send an interconnection request to ISO via the Interconnection Request Tracking Tool (IRTT). Existing customers can create an account through IRTT, while new customers must first or simultaneously obtain an ISO customer ID and access critical information about energy infrastructure. Once ISO has completed the required courses, work with ISO and the transfer owner on an Interconnection Agreement (AI), a formal document that lists the terms and conditions of the interconnection service. You must perform an AI before you can build or operate an elective transmission generator or upgrade. The final steps in the interconnection process are to submit the final data and register your asset with ISO. To provide energy and/or capacity in New England, new resources must be connected to the managed transmission system. Please note that distribution facilities should inquire with their local transport owner if they are subject to the ISO connection process.
