The Results

After three months of intense focus, camaraderie and, both virtual and in-person learning, we are excited to announce Rock Rabbit as the Energy 2024 winner. The company delivers an AI-powered platform and app that makes it fast, easy and reliable to find and claim incentives for green home upgrades. Chosen through a peer-review process, the company received a $25,000 award and a pilot project awarded by Burlington Electric Department (BED). BED also awarded a pilot project Moduly, which is a smart energy system behind the meter integrating plug-and-play home energy storage and IoT devices in a single ecosystem. Additional Vermont companies and utilities are in talks with cohort companies to implement further pilot projects.

The 2024 challenge

To be part of a competitively selected cohort of start-up and/or seed stage ventures who offer innovative products or services aimed at reducing greenhouse gas emissions in an effort to help Vermont meet its climate goals. Start-ups addressing the decarbonization of buildings, transportation, heating and industrial processes through electrification, biofuels, thermal energy networks or other renewables with a particular focus on load management controls integrated with storage, heat pumps, electric vehicle charging equipment and building systems are encouraged to apply. Ventures that address energy burden for under-represented and low to moderate income populations are of particular interest.

The eighth DeltaClimeVT energy and climate business accelerator program is designed to accelerate the drive towards a zero-carbon future for Vermont, by helping Vermont’s utilities increase adoption of clean energy, smart building and electric vehicle technologies that enable the integration of distributed energy resources with the grid. Entrepreneurs will work directly with Vermont utilities throughout the program to contribute to Vermont’s Comprehensive Energy Plan (90% renewables/efficiency by 2050) and Burlington’s Net Zero by 2030 goals.

We were particularly interested in services and technologies that have wide potential applicability in rural locations and that allow commercial and industrial (C&I) businesses, low and moderate-income Vermonters, underrepresented populations and multi-family building residents to participate in the emerging low-carbon economy.

Examples of technologies or services could include but are not limited to:

  • Smart building technologies such as building controls, dynamic EV charging equipment (V2X), heat pump load management, storage and other devices that can align with utility demand response signals and support data verification;
    • Especially technologies that can overcome communication challenges with limited broadband access, cellular networks, and radio signals with a particular focus on open ADR (due to mountainous terrain);
    • Especially lower cost solutions where aggregator integration costs and software fees are affordable for smaller utilities with fewer connected/controlled devices;
  • EV and EV charging services and technologies related to V2G/V2H/V2X, commercial EV fleet services and telematics;
  • Thermal energy network technologies and services with a focus on community scale systems utilizing waste heat and/or ground source heat pumps;
  • Service models designed to eliminate engagement and participation barriers for underserved customers and encourage whole home decarbonization; and/or
  • DIY electrification opportunities that relieve the need for contractors.

About the Program

The DeltaClimeVT business accelerator program is managed by the Vermont Sustainable Jobs Fund and facilitated by ecosVC. The program is centered around the ecosVC Lens of the Market® ACCELERATED curriculum, designed to ensure participating startups produce a well grounded case for their business and are able to articulate a compelling plan for success to investors.

The program features an extensive online curriculum plus 1-1’s facilitated by ecosVC principals, active engagement with sponsoring Vermont utilities, business mentors, investors and successful venture leaders. Startups must have at least two senior members of their team actively participate in all aspects of the program. The program includes two online and two in-person intensive sessions (each 2-4 days in duration), weekly assignments and bi-weekly webinars as well as frequent 1:1 engagement with program leaders and mentors. Active engagement and peer-mentoring by participants is an essential part of the program and a final award of $25,000 is provided to a peer-selected company. The DeltaClimeVT program managers work to ensure that startups in the cohort are non-competitive.

“It’s just incredibly humbling, to say the least. The corporate partners and the mentors of the DeltaClimeVT program have been incredibly generous with their time. I’ve never experienced anything like that. Everyone said yes to having a conversation. And then they were very candid about providing feedback, even if sometimes it wasn’t always the feedback you wanted to hear but it helps make your company better and it helps make you develop a product that’s better so that’s been incredible. We’ve been in a few accelerators – this has been the best by far.”

Noteworthy AI helps utilities evaluate the condition of the electric distribution grid at-scale using vehicle-mounted cameras, edge computing and computer vision. As the vehicles drive, the camera system autonomously geolocates, photographs and analyzes grid assets to help utilities gain grid intelligence across several applications, including: asset inventory/GIS clean up, asset inspections, vegetation management, 3rd party attachment assessments, lighting and more. By automating this data collection and analysis process, Noteworthy can significantly increase situational awareness on the distribution grid while reducing operations and maintenance costs.
