There are two major steps involved in the interconnection process: applying for interconnection and receiving permission to operate (PTO).
GalleryInverter-Based Resources Reactive Power Capabilities
This is the third of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.” Here’s the last article – “Reactive Power and Transmission & Distribution Operations” – in case you need to catch up.
Inverters are a key component of any Inverter-Based Resources (IBR) facility, including utility-scale solar PV. Because of their ability […]
GalleryReactive Power and Transmission & Distribution Operations
This is the second of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.”
In Part 1 of this series, we looked at the differences and relationship between real, reactive, and apparent power. We also looked at the production and absorption of reactive power by equipment such as transformers, reactors, and capacitors.
Before we […]
GalleryWhat Are Reactive Power and VArs?
This is the first of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.”
Right after I started my first job out of college, I found myself presenting at a meeting and talking about reactive power and VArs. These were very senior-level engineers, and, although I didn’t recognize it at the time, never […]
The Most Important Factors When Specifying a Transformer
Going from designing residential solar systems to commercial and industrial (C&I) solar systems requires new knowledge in many areas. One area in particular is equipment selection. When megawatt-scale solar systems are designed and put into operation, medium voltage electrical equipment must be properly selected for safe and optimal operation. In this excerpt from Megawatt Design, […]
GalleryUtility-Scale Solar PV Flourishes Despite Mixed Business Conditions
In September 2023, SEIA and Wood Mackenzie released its “Solar Market Insight Report Q3 2023” report. The report projects more than 20 GW of additions in utility-scale solar in 2023, up from 11.8 GW in 2022.
Last month, EIA reported that nearly 17 GW of utility-scale solar was added in the first half of 2023.
These reports […]
