For grid-connected commercial and industrial (C&I) customers, the demand charges associated with peaks in consumption during high-use periods can be substantial–up to 70% of the customer’s utility bill–and peak shaving is a great option to reduce these costs. In fact, a just-released National Renewable Energy Laboratory (NREL) survey of U.S. demand charges found that more than 25% of commercial utility customers (or about 5 million customers) in the U.S. alone would benefit from reducing peak demand consumption.
I launched this “From the Founder” column last month and used it to go back to HOMER’s roots as a mechanism to serve the energy access world. This month, I want to continue the conversation about how to rapidly and efficiently help millions of people understand how distributed power systems work — at the opposite end of the spectrum. Specifically, I’m referring to companies and organizations that are serious about being competitive in […]

Version 3.7, released in August 2016, introduced three new ways for users to supplement or replace the default load following and cycle charging strategies HOMER has used for decades. Moving HOMER to an Open Platform to Meet Modern Challenges “HOMER was originally created in 1993, when microgrids […]
