New Course: Pre-Construction in Utility-Scale Solar The subcontractors you select, the contracts you put in place, and the commercial foundations you establish before construction starts will shape every aspect of project execution. A well-run pre-construction (pre-con) process is one of the highest-leverage things an EPC can… Continue reading “New Course: Pre-Construction in Utility-Scale Solar”
New Course: Owning the Customer Interconnection Experience Many people get introduced to interconnection the same way: someone hands them a stack of utility paperwork and says, we need these filed. So they do. They submit the applications. Then a problem comes up, and they realize there’s a… Continue reading “New Course: Owning the Customer Interconnection Experience”
New Course Announcement: Transformer Specification & Applications for Inverter-Based Resources As many residential solar designers move up into larger C&I and utility-scale projects, the work starts to look pretty different from a rooftop install. Transformer specification is one of those areas where the learning curve shows up fast and where… Continue reading “New Course Announcement: Transformer Specification & Applications for Inverter-Based Resources”
How the Future of DER Interconnection Could Mirror the Evolution of Booking a Flight The interconnection process can make or break a project. And yet, it’s difficult to tell exactly how bad the bottlenecks truly are. Distribution-level interconnection data is fragmented across more than 3,000 utilities regulated by 50 different states, with few central… Continue reading “How the Future of DER Interconnection Could Mirror the Evolution of Booking a Flight”
What is an Energy Market Forecaster for ESS?
