Multi-stakeholder Microgrid Ownership Model Provides ‘Win-win-win’ Solution

multi-stakeholder-microgridsPartnering between community, government, and industry helps piece together an affordable, sustainable microgrid puzzle.

Public-private partnerships, multi-stakeholder microgrid ownership, public-purpose financing, cooperative ownership, microgrid-as-a-service (MaaS)… It’s fitting that there are multiple monikers for a multi-benefit microgrid financing tool in which ownership is split between several entities. The multi-stakeholder microgrid ownership model challenges the often prohibitive private sector financing models that may disregard the public service microgrids can provide. Owners, partners, and stakeholders may include citizens, small businesses, tech services providers, utility companies, and government entities. This small but growing […]

Grid-scale or Local Renewable Energy: Change Your Shirt or Change the World?

corporations-microgrids-renewables

 You’re running out the door for a date, and you’re late, and you’re maybe not looking quite how you want to look. Sure, you’d love to take a shower and put on brand-new clothes, but instead, you go the easy route: grab a clean shirt and head out the door. When large companies claim that they are going “100% renewable,” what they mean, in all but a few notable cases, is that they […]

The Hydro Empowerment Network (HPNET), co-founded by Dipti Vaghela (left) in 2012, brings practitioners a knowledge exchange platform to advance micro-hydro power. HPNET focuses primarily on “policy, technology, and socio-environmental aspects for sustainability.” Vaghela, who serves as HPNet’s coordinator, talks to Microgrid News & Insight in this first of a two-part interview. In part 1, Vaghela talks about the benefits of micro-hydro and the connection between local communities and project successes.   MGN: Micro-hydro power is […]

Part 1 of this post addressed the issue of global energy poverty in rural areas: its implications, challenges, and promising developments in African nations and in India. Part 2 addresses off-grid problems in Haiti, potential microgrid solutions in Alaska, and the population-empowering “Minigrid Game.” Haiti struggles with extreme energy poverty Haiti is the poorest nation in the Western Hemisphere. Seventy-five percent of Haitians lack electricity access and must cook and light their homes with […]

Ending Worldwide Rural Energy Poverty with Clean, Off-grid Solutions: Part 1

More than 1.2 billion people worldwide lack basic access to electricity. According to the International Energy Agency (IEA), 95% of these people are in Sub-Saharan Africa and developing Asia, and 80% are the rural poor. Providing reliable, resilient clean energy to the world’s often remote, off-grid rural communities gives these communities the power (in both senses of the word) to run businesses, create new economic opportunities, and ultimately improve health and sanitation while increasing […]

Cuomo’s Reforming the Energy Vision (REV). REV […]

Main-grid and Microgrid Bankability in Africa: A Comparison

Clusters of gas-fired turbines, big dams, and geothermal projects in Sub-Saharan Africa tend to have very complex financing structures. In addition, they also often involve complex debt/equity structures from local banks. Microgrids, however, are within the reach of much smaller organizations.

Microgrid Antifragility: Don’t Be a Turkey

Like banks “too big to fail,” the grids in most developed nations are so fragile and interdependent that they are vulnerable to natural or human-made disasters that can cripple whole cities and regions. Microgrids, however, are like your local bank: independent from other local banks and thus much more resilient to unexpected future events. Resilience is an obvious  benefit of breaking the grid system into smaller components independent of each others’ operation. But […]

RISØ Report Concludes Danvest System Delivers Power Quality in Microgrid Applications

Danish national research institute RISØ, a world leader in setting standards for the modern wind industry, has released a report on power quality in diesel-wind microgrid-based hybrid systems.  RISØ measured performance using a Danvest Hybrid Power Plant running with a Vestas 600kW wind turbine. The institute tested voltage and frequency fluctuations during continuous operation as well as during transitions between different states of operation. The report concludes that frequency and voltage vary very little, both […]
