Jes Rivas



Jes Rivas is a building systems engineer with more than 15 years of experience in technology assessment, market characterization, and evaluation. Her expertise spans a wide range of commercial, industrial, and residential programs and measures with a focus on emerging technology, demand response, and the internet of things (IoT). She leverages her engineering background and industry experience to help her clients design for and achieve meaningful results while negotiating a rapidly evolving landscape. With a reputation for exceptional project management, Jes is a trusted advisor who values client service and reliable, consistent, and authentic communication. Recently, Jes developed ILLUME’s pipeline development model that allows utilities to look across their energy portfolio, scan and understand opportunities, and then test and launch new offerings. For the past two years, she has drawn together qualitative and quantitative streams at ILLUME to create a practice designed to research and shape markets. This work is meant to sow the seeds for technology transfer and is enabled by a deep and holistic understanding of markets, channels, and the communities and trusted messengers who support them. When Jes is not helping clients future-proof their portfolios, you can find her exploring the Pacific Northwest’s natural beauty.

Jes is located in San Diego, CA.
