Think about a extreme storm knocks out a neighborhood powerline; whereas most properties go darkish, one home-owner seamlessly manages their backup vitality, prioritizing vital home equipment. This isn’t the longer term—it’s occurring now with SPAN’s sensible electrical panel.
SPAN is the one startup firm to undergo two of the Nationwide Renewable Power Laboratory’s (NREL’s) startup help packages: the Shell GameChanger Accelerator Powered by NREL (GCxN) and the Wells Fargo Innovation Incubator (IN2). SPAN created a sensible electrical panel that goes past conventional capabilities, permitting customers to manage particular person circuits for particular person gadgets. SPAN additionally has an app that gives customers with a dashboard to maintain monitor of the related home equipment and electrical hundreds. The panel gives real-time visibility into a house owner’s vitality consumption, damaged out by particular person breakers, so owners can prioritize totally different hundreds throughout an influence outage, whereas utilities can achieve perception into grid flexibility methods.
When NREL Senior Engineer Bethany Sparn had SPAN’s sensible panel put in in a lab, all of the laboratory electricians have been enthusiastic about it.
“The electrician that installed the panel asked me how it worked, and I explained that every circuit had a dedicated power meter and relay, all hidden in the backplate of the panel,” Sparn stated. “They thought it was really cool. The SPAN panel shook up the world of breaker panels in a way that feels like the early days of smart thermostats. They created a product that would be beneficial to utilities and consumers.”
SPAN Vice President of Enterprise Growth Alex Pratt stated the corporate reimagined an influence panel from the bottom up.
“Each of the circuits in our panels are granularly metered and controllable through a relay,” Pratt stated. “This combined with significant onboard processing and multichannel communications creates a powerful platform to provide novel home energy management capabilities.”
The primary undertaking that introduced SPAN’s know-how to NREL was by way of the GCxN program in 2019. NREL scientists, together with Senior Analysis Engineer Shibani Ghosh, centered on simulations to check the doable impacts of excessive adoption of SPAN panels on the neighborhood scale beneath a utility’s distribution feeder. The simulations demonstrated how grid operations may enhance and assist utility shoppers when particular person consumptions are managed by SPAN sensible panels.
“If a smart panel like SPAN’s can communicate and track when the electricity price goes down,” Ghosh stated, “you can schedule the operation of your devices and save money within your time preferences.”

The outcomes of the simulations supported that SPAN’s panel may ship grid advantages as anticipated, in order the GCxN undertaking wrapped up, SPAN joined IN2 in 2020, initiating Sparn’s work with the sensible panel within the lab.
“SPAN was unique in that they had already gone through GCxN, but that had been an entirely simulation-based project,” Sparn stated. “For IN2, we wanted to get their hardware in the lab. We wanted to look at a number of features that could help people add electrical equipment or provide resilience. For instance, if you install their panel with a backup battery, you can change what circuits are powered during a grid outage and even prioritize them.”
Pratt factors to a concrete instance of how the panel operates and gives worth when a house owner goes to put in a brand new electrical load within the dwelling, comparable to an electrical automobile (EV) charger or warmth pump. These additions may exceed the quantity of electrical energy the house was initially designed to attract.
“The panel eliminates the need for the consumer to upgrade their service level with a utility and instead will intelligently balance the loads in their home automatically,” Pratt stated.
The laboratory testing of the panel confirmed that its superior options, comparable to turning off circuits to keep away from overloading {the electrical} service and configurable backup energy, have been working as anticipated. The IN2 laboratory experiments laid the groundwork for additional collaboration between SPAN and NREL.
Along with the GCxN and IN2 packages, one other collaboration alternative was led by Xin Jin, NREL group supervisor for Grid Edge and Superior Controls on the Constructing Applied sciences and Science Middle. Jin and his group developed a man-made intelligence (AI)-driven dwelling vitality administration system, known as foresee™, which received an R&D 100 award in 2018. By means of a cooperative analysis settlement after the IN2 undertaking, Jin explored how integrating SPAN’s panel with foresee may generate extra advantages.
“This maximized the work NREL did with SPAN through the GCxN and IN2 projects,” Jin stated. “With their panel and our software, we can modulate the thermostat, manage EV charging, and control the water heater. We can talk to every major load in the home. By combining their panel and circuit-level power metering with foresee, there is more control, and that translates to utility bill savings.”
NREL’s foresee software program makes use of superior algorithms that be taught the dynamics of every dwelling together with its occupants’ patterns to foretell future vitality consumption. Automated management of related home equipment and methods will save vitality, cut back pressure on the grid, and will save owners as much as $9 billion on vitality payments—with out asking folks to turn into vitality consultants. Launched in 2018, it was a big breakthrough within the dwelling vitality administration market, attracting curiosity from startups and enormous HVAC producers.
SPAN continues to scale up in the way in which it really works with NREL. The corporate began in California and Hawaii, and its panels are actually broadly deployed in all 50 states, supported by a community of a whole bunch {of electrical} installers. Whereas owners and contractors have historically been SPAN’s audience, additionally it is exploring functions for utility grid providers.
“As we’re trying to introduce a new category and new approach to home energy management technology, having the credibility from a partnership with an entity like NREL is invaluable,” Pratt stated. “We’ve proven the viability and value of our product. We are now focused on accelerating adoption, and electric utilities represent a step-function change in the scale we can achieve and impact we can have.”
The SPAN panel made an enduring influence on the NREL researchers, they usually stay enthusiastic about its potential.
“Their panel is really sleek,” Jin stated. “It’s like an art piece—it’s very beautiful and well built. In terms of function, it’s very advanced.”
