Sigora Microgrid Provides Affordable, 24/7 Power to Haiti’s Impoverished Communities

Sigora HaitiSigora Haiti microgrid lights up Môle-Saint-Nicolas

How is it that the poorest country in Western Hemisphere is home to one of the world’s most sophisticated microgrid projects? Maybe fate has determined that the embattled people of Haiti deserve a break, after decades of earthquakes, hurricanes, massive flooding, corruption and gruesome political oppression. Or, maybe it’s because a group of idealistic energy geeks, together with a team of determined Haitians, decided to bring renewable energy to a rural  health clinic. […]

HOMER Energy Explores Microgrid and Renewable Energy Solutions for Puerto Rico

Close to three months after Hurricane Maria swept across Puerto Rico, utterly destroying the island’s electrical grid – as well as countless homes and communities –  much of the island is still without power. And, where power has been restored, it is often unreliable. Puerto Rico’s aging electrical grid was already in bad shape, but a direct hit from Category 4 storm Maria dealt a catastrophic blow to the infrastructure of the Puerto […]

HOMER to Present at CO Distributed Generation Workshop, December 4, 2017

How Can Small-Scale Wind and Solar Producers Optimize Their Energy Development Decisions? The Distributed Wind Energy Association (DWEA) will be presenting a day-long workshop on distributed generation in Yuma CO, with a focus on northeast Colorado’s clean energy future. HOMER Energy VP of Sales, Dominick Morone, will be presenting “It’s All About the Economics.” The talk will highlight specific opportunities that HOMER Pro presents for the farmers, agricultural producers and small scale commercial energy […]

So, What is a Microgrid, Exactly?

what is a microgrid

Extreme weather events, environmental concerns, and energy economics are bringing microgrids into public discourse in the grid-connected world. The energy landscape is suddenly changing very quickly, and microgrids are a big part of that change. The entire world — every corner of it — is finally looking at the potential for microgrids to fill many needs. But what is a microgrid? A microgrid can be defined as an independent power network that uses […]

Combined Dispatch Algorithm “Two-for-one Deal” Accurately Models Microgrid Controller

combined dispatch algorithm

By Cycle Charging during periods of low net load, the Combined Dispatch algorithm helps avoid using a diesel generator at low loads. By Load Following during periods of high net load, the algorithm maximizes the use of available renewable energy. Due to this flexibility of being able to account for both high and low loads, the Combined Dispatch algorithm is a better option than choosing between Load Following or Cycle Charging (and potentially making the wrong choice). It is also a better option than running both strategies by default, which doubles the processing time. On top of that, we’ve seen that Combined Dispatch can perform as well, if not better than, either Load Following or Cycle Charging.

Guest Blog by Navigant Research’s Peter Asmus: Data Centers as Microgrids – Moving toward Utility Interdependency

This blog post was written by Peter Asmus, Principal Research Analyst at Navigant Research. HOMER Energy is proud to be a media sponsor of Navigant’s upcoming webinar on October 24th: Data Centers and Advanced Microgrids.   The forecasted growth of Internet of Things devices and the rapid uptake of cloud-based applications to manage the emerging digital economy speak to a fundamental fact: the role data centers will play in our lives will continue […]

I recently had an opportunity to visit the on-site training campus of Solar Energy International (SEI), located in Paonia, Colorado, a quaint town of 1500 people in western Colorado. I was so impressed with SEI’s mostly outdoor training center, in a spectacularly beautiful location, that I wanted to share it with you. HOMER Energy’s focus for the next month is to highlight the urgent need for millions of people to understand how small-scale, […]

A New HOMER to Help Millions Learn About Microgrids

educate millions about microgrids

HOMER Energy CEO Dr. Peter Lilienthal discusses how to educate millions about microgrids. The advent of electricity created disruptive change in the world. Now, the world of electric power is about to undergo a massively disruptive change itself. The rapidly declining cost of solar and batteries is ushering in a new era of clean, reliable, local electricity generation, and an end to the era of ever-bigger power plants and large transmission lines. These […]
