About this course

Launching August 2024
These courses will be submitted to IEEE for qualifying for CEUs.
 

The U.S. Energy Information Administration expects a record addition of utility-scale solar in 2024, if the scheduled 36.4 GW are added to the grid. This growth would nearly double last year's 18.4 GW increase, which was itself a record for annual utility-scale solar installation in the United States.

With this huge increase in utility-scale solar, developers and designers may need to upskill their teams with a foundation in transmission. Electric power transmission in the U.S. is a complex topic and it can be difficult to find timely and concise resources on the subject.

That's why Tim Taylor, Owner of Electric Distribution Academy, created this 2-course series. 
  • Introduction to Electric Transmission provides professionals with a basis for working with electric power transmission, including a knowledge of how the industry is structured and operated in the US, transmission stakeholders, and the equipment and facilities that comprise transmission.
  • Interconnection of Utility-Scale Solar PV to Transmission builds on the first course to cover transmission systems and electric power equipment, transmission operators interconnection procedures and requirements, specialized system studies, and solar PV interconnection equipment and control, with aim of this course to boil down the most important concepts to a level where everyone can get an understanding of the very involved and complex task of interconnecting solar PV to transmission systems.

Solar PV Interconnection to Transmission - Current State and Challenges

In this module, generation interconnection to transmission is introduced. We look at the current state of interconnections, trends, and challenges. We discuss the goals of successful interconnections from the perspectives of generation developers/owners and from transmission owners and ISOs. Transmission owner interconnection requirements are reviewed.

We go over important FERC Orders that continue to shape interconnection processes in the US, including FERC Orders 2023, 1920, and 1977. We look at FERC's pro forma LGIP and LGIA, that form the basis of transmission providers' interconnection processes and agreements. We look at OATT's (Open Access Transmission Tariffs) and their role in generator interconnection. We also have a look at the most significant NERC federal regulations pertaining to generator interconnections.

Processes for Generator Interconnection to Transmission

In this module we take a look at processes for generator interconnection to transmission. We step through typical generator interconnection processes for Large Generators and the steps in the process. We focus on the "First Ready, First Served Cluster Study" approach, recently mandated by FERC 2023 "approach and which replaces "First Ready, First Served Study" still in use at some transmission providers. We also take a look at each ISO/RTO in the US, and what the current status of generator interconnections are in each one.

Technical Studies for Generator Interconnection to Transmission

For each proposed generator interconnection, the transmission provider (or designated consultant) performs a series of studies, called the Cluster Study, Cluster Re-Study (as-needed), and Interconnection Facilities Study.  An Affected System Study and additional re-studies are performed as needed. We take a look at these studies, data requirements, what they entail, and what their results are.


We discuss the different types of studies, including frequency-domain power flow, short-circuit, and transient stability. We also look at the emerging requirements for EMT (Electromagnetic Transient) time-domain simulations, the reasons why they are being requested, and how they impact the generator interconnection process.  We discuss contingency studies and the concept of transfer distribution factor (TDF).
 We look at example reports from actual studies, and discuss their meaning.
