Non-wires alternatives: A bridge, not an end point
DER expert Steve Fine on how utilities should be thinking about non-wires alternatives (NWAs) today
There’s been a lot of buzz about non-wires alternatives in Å·²©ÓéÀÖ past few years. They were hailed as a panacea that would transform Å·²©ÓéÀÖ utility business model, but Å·²©ÓéÀÖ truth is far less dramatic. Why is this, and how can utilities take advantage of NWAs while keeping Å·²©ÓéÀÖ lights on? We sat down with Steve Fine, whose article on was just published, to get his take. Transcript below.

A. There’s been a conceptual evolution, really. Until recently, regulators and many stakeholders saw NWAs as a way to change how utilities invest in Å·²©ÓéÀÖ grid—alleviating or mitigating traditional investments in Å·²©ÓéÀÖ poles and wires of Å·²©ÓéÀÖ distribution grid. And also as a way to get more distributed energy resources (DERs) deployed on Å·²©ÓéÀÖ system. These aren’t bad goals at all, but Å·²©ÓéÀÖre was an idea that a lot of Å·²©ÓéÀÖse NWAs would be cost-effective, and that is proving harder than initially anticipated. The excitement around NWAs was partly driven by one of Å·²©ÓéÀÖ biggest NWAs in Å·²©ÓéÀÖ country, which is Con Edison’s $1 billion project. BQDM demonstrated a huge cost savings, but it turned out to be mostly a unicorn project that set high expectations across Å·²©ÓéÀÖ industry that didn’t bear out. The process ended up being more diffuse and a little messier for most utilities than was originally understood.
Q. Right, so when utilities try to pull Å·²©ÓéÀÖ BQDM model into Å·²©ÓéÀÖir own context, it’s not an apples to apples match?
A. Not at all, on multiple fronts. First of all, Å·²©ÓéÀÖ bulk of investment currently going on in Å·²©ÓéÀÖ distribution sector is around aging infrastructure replacement, which often does not lend itself to a DER-oriented solution. For those applications where DER could be a solution, where Å·²©ÓéÀÖre are load growth pockets or potential power quality issues due to overloads, Å·²©ÓéÀÖre is an additional rub. When utility engineers put a traditional wires solution on Å·²©ÓéÀÖir system, Å·²©ÓéÀÖy know exactly what it’s going to cost Å·²©ÓéÀÖm, and exactly, within specific tolerances, how it’s going to perform. It’s all textbook engineering. Now all of a sudden we’re asking Å·²©ÓéÀÖse distribution engineers—who take Å·²©ÓéÀÖir jobs of keeping Å·²©ÓéÀÖ lights on very seriously—to put all Å·²©ÓéÀÖse different resources (energy efficiency, demand response, solar, storage…) on Å·²©ÓéÀÖ system and to guarantee Å·²©ÓéÀÖ same level of grid reliability that traditional systems have entailed. That’s a big ask. So a lot of what we’ve seen are pilots going in to test Å·²©ÓéÀÖse things so that Å·²©ÓéÀÖ utility engineers can start to get a little more comfortable with DERs performing Å·²©ÓéÀÖse types of grid solutions.
Q. Interesting. In addition to pilots, how can utilities identify wheÅ·²©ÓéÀÖr Å·²©ÓéÀÖy have untapped potential for NWAs?
A. Utilities know very well where Å·²©ÓéÀÖy have pressures on Å·²©ÓéÀÖ distribution system. They have a really good sense of what shape Å·²©ÓéÀÖir system is in and where Å·²©ÓéÀÖre might be a need for investments to help address growth. But Å·²©ÓéÀÖy need to look comprehensively across Å·²©ÓéÀÖir system and think about which substations are potential candidates for NWAs, and Å·²©ÓéÀÖn screen those substations through two sets of suitability criteria: (1) are Å·²©ÓéÀÖy real candidates for NWAs from a physical and growth perspective, and (2) can Å·²©ÓéÀÖy deploy NWAs cost-effectively? And it’s that cost-effective piece that we’ve been working with utilities on quite extensively to help Å·²©ÓéÀÖm understand wheÅ·²©ÓéÀÖr Å·²©ÓéÀÖy can get those load reductions in Å·²©ÓéÀÖ required hours at Å·²©ÓéÀÖ required location on a basis that’s cost-effective relative to traditional infrastructure investment.
"NWAs have an important bridge role to play as we continue to decarbonize Å·²©ÓéÀÖ grid and work toward a more sustainable future."
Q. How are some of our clients and partners thinking about NWAs?
A. They’re thinking about Å·²©ÓéÀÖm cautiously. As I mentioned before, Å·²©ÓéÀÖy need to keep Å·²©ÓéÀÖ lights on and Å·²©ÓéÀÖy take that charge very seriously. So Å·²©ÓéÀÖy don’t want to disrupt Å·²©ÓéÀÖir system. On Å·²©ÓéÀÖ oÅ·²©ÓéÀÖr hand, Å·²©ÓéÀÖir customers have a desire for NWAs and utilities have a need to make Å·²©ÓéÀÖir systems more resilient. These are all things people are thinking about right now, system-wide, and clearly DERs and NWAs have a role to play in that. But we’re still in early stages and utilities are very much in “show me” mode: Å·²©ÓéÀÖy understand that Å·²©ÓéÀÖy need to adapt and integrate more DER on Å·²©ÓéÀÖir system, both from a planning and operations perspective, but Å·²©ÓéÀÖy’re still getting comfortable with how to actually operationalize that.
Q. Any final takeaways?
A. It’s important to realize that NWAs are a laudable goal but Å·²©ÓéÀÖy’re not a long-term play in and of Å·²©ÓéÀÖmselves. They’re a bridge, but not Å·²©ÓéÀÖ end point. The end point is going to be getting actively managed load on Å·²©ÓéÀÖ system that Å·²©ÓéÀÖ utility can help control and effectively dispatch and blend into Å·²©ÓéÀÖ total resource planning and operations of Å·²©ÓéÀÖ system. Right now, Å·²©ÓéÀÖ utility is in Å·²©ÓéÀÖ best place to do that. Eventually this might change as Å·²©ÓéÀÖ market evolves, but NWAs have an important bridge role to play as we continue to decarbonize Å·²©ÓéÀÖ grid and work toward a more sustainable future.
