What 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 […]

Utility-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 […]

Grading the States: Clean Energy Adoption and Access to the Grid

One difficulty that solar PV and other clean-tech companies face when looking to expand their business into other states is that every state is different – different in their goals, policies, interconnection processes, technical standards, data availability, and other factors.

For solar PV companies like developers, EPCs (Engineering, Procurement, and Construction), and contractors, it’s about questions […]

Power Flow Studies on Utility Distribution

If you work with utility-scale or community solar PV, you may have heard the utility refer to the term “power flow study”, also called “load flow study”, and wonder what that is.

Utility distribution feeders are designed and operated at medium voltage, also called primary voltage, which is typically between 4 kV and 35 kV in […]
