If you are a renewable developer interested in connecting your resource into the MISO transmission grid, the time to move is now

The MISO definitive planning phase (DPP) 2021 cycle window is currently open and will close on July 21, 2021 at 5:00 PM EST. To prepare for your application, you can view the application checklist in Figure 1. Before getting started, there are many project details to consider, including opportunity identification, technology selection, comprehensive sizing and siting, and how to properly submit the application package. And, perhaps most important, is understanding the proper MISO interconnection requirements and specific processes and timelines—which is key to your project success. But where do you start?

How can I navigate the complex interconnection journey in MISO?

For new and existing non-member entrants, the interconnection journey in MISO can be complex and, at times, intimidating. As a non-member entering the MISO queue, you must ensure you have the right support with the capability to manage not only the application package development and submission, but also the relevant access to the database (which is required seven months after MISO sends the notice of a model review, and only allows 10 days to respond).

How will I know where—and what resource—to connect to the grid?

With ever increasing penetration of renewable projects—as well as transmission, permitting and environmental constraints—it is important to make educated decisions on which location and which resource to connect to the grid to maximize the short- and long-term benefits vs. the cost. Project developers need to consider many factors, including reliability, environmental, permitting, and wholesale market limitations. These factors may not seem critical at the early stage of development, but if not properly planned for, they can substantially impede the success of a project and investment in the long-term. As partner in this decision-making process, DNV’s Resource Sizing & Siting tool provides a comprehensive solution that layers all considerations into one platform (see Figure 2).

How can I avoid technical risks?

Apart from our support to deregulated entities (e.g., renewable developers), DNV’s Power System Advisory team has been supporting electric utilities and ISOs in evaluating the submitted generation interconnection requests and assessing potential acquisition risks for more than a decade. Our engineers have helped in the submission of over 300 interconnection applications across all ISO/RTO regions in North America.

Knowing how a utility or ISO evaluates interconnection and analyzes such renewable projects (during various phases of a DPP cycle), is critical in foreseeing any associated technical risks during the early stage development.
