Brian Poeltl, PE, a senior electrical engineer and project manager at BL Companies, authored a piece for POWER Magazine on why the future of solar growth rests on how effectively new generation can be integrated into the grid. Energy demand is rising rapidly with the proliferation of data centers, electrification and EV charging. Smart inverters and flexible interconnection, not multimillion dollar infrastructure upgrades, is the real key to expanding solar’s capabilities. In this excerpt, Brian explains the predicament facing distributed generation solar projects:
In theory, the process is straightforward. Engineers submit detailed electrical drawings, equipment specifications, and a site or roof plan to the utility. The utility reviews the local circuit and substation to confirm that it can safely accommodate the power. If the system can handle the generation, the project proceeds.
The reality is very different. I’ve seen clients line up land, secure financing, finish their engineering, and then sit in limbo. Depending on the state and utility, an interconnection review can take anywhere from nine months to four years. These delays reshape the economics of entire portfolios of DG projects. Owners lose interest. Incentive windows close. The finance community begins to doubt whether a project will ever reach construction and energization. Some developers eventually walk away.
Fortunately, new tools are emerging that can ease this bottleneck. Smart inverters and flexible interconnection strategies make it possible to connect projects more quickly and at lower cost, even on circuits that may appear constrained.
