Buffering batteries placed near transmission constraints are rarely listed among grid enhancing technologies. The usual list includes advanced conductors, dynamic line rating, and power flow control devices. All of those technologies increase the instantaneous capacity of transmission lines. Batteries do not do that. A battery cannot turn a 500 MW … [continued]
Dynamic line rating can produce large savings in some parts of the electricity system. In other cases it reveals that operators had been overestimating how much cooling transmission lines receive from the surrounding air. Both outcomes matter. Dynamic line rating replaces assumptions with measurements and forecasts about what transmission lines … [continued]
The series examining Oʻahu’s energy transition has followed a consistent structure. It began by defining the island’s fully electrified energy system and stripping away energy uses that do not serve the civilian economy. Aviation fuel for flights leaving Hawaiʻi, maritime bunkering for ships crossing the Pacific, and military energy consumption … [continued]
I’m preparing to speak to engineers at GE Vernova during Engineering Week at the request of Cornelis Plet, CTO of GE Vernova Grid Systems Integration. It is a useful moment to step back and look at a class of technologies that rarely make headlines but quietly shape how modern power … [continued]
The US startup SOLRITE is opening up a new energy storage opportunity for residential ratepayers to participate in money-saving VPPs, whether or not they have rooftop solar panels.
Nearly a decade ago, I gave a presentation at EVBox’s rEVolution conference in Amsterdam. One of the other presenters at the even was the head of The Mobility House, founder and then-CEO Thomas Raffeiner. The company’s focus: vehicle-to-grid technology. It was clear he and The Mobility House had been working … [continued]
TL;DR — Public charging is expensive and messy because the business model is wrong. Instead of selling electricity, charging operators should just provide infrastructure — and utilities should bill drivers directly at their home rate. A single API can make this happen and unlock the kind of seamless experience Tesla … [continued]
Gagan Dhillon, CEO of Synop, and I sat down recently to discuss why electric school buses are the perfect starter V2G fleet, real-world results from electric school bus V2G programs, making electric school bus (and other EV) fleets pencil out after the federal tax-credit cliff, EV fleet energy management, and … [continued]
Several months ago, when I conducted an interview about a new energy storage system in the Shetlands, I didn’t know the GEMS software was involved. By happy accident, it turns out Wärtsilä Energy Storage recently had some news about GEMS Pulse, so it was possible to do another one with … [continued]
Solar power is the dominant form of new electricity generation capacity globally now. That’s because it has become the cheapest option for new power capacity in locations all around the world. However, to maximize the usefulness of solar power, people have innovated and been creating more and more ways of … [continued]
