When Disaster Response Drives Transformational Change to Grids, Fuel Cells are the Preferred Choice of Many Energy Prosumers
The increasing frequency of weather-related disasters puts emergency disaster response in the headlines often and encourages more and more systematic solutions. In the example of wildfires in the U.S., where 30,000 fires burned over 3.5 million acres between January – August 2019, systematic solutions are crucial. Seeking to minimize fire damage, utilities in California have instilled the ...

Structure-preserving dynamical model and distributed stabilisation of electricity infrastructures with renewable energy resources
This paper introduces a module-based approach to modelling and controlling electricity infrastructure with a high penetration of distributed renewable energy resources. Each energy-converting component is defined as a module and is represented in terms of its local variables and the interaction variables between the module and the transmission network. The structure of the electricity ...

Rhode Island Hospital’s Journey From The Sidelines To Optimized Demand-Side Energy Management - Case study
When a new EPA law threatened demand-side energy management at the largest hospital in The Ocean State, CPower answered the call. The moment he learned what the EPA’s law meant for diesel generators participating in demand-side energy management, Marc Leduc figured he and Rhode Island Hospital had a problem. The largest hospital in its state, Rhode Island Hospital is the only Level I ...

6 reasons smart grids need green, digital and more secure ring main units (RMU)
Globally, every industry is accelerating decarbonization initiatives. Buildings and factories are becoming more electrified by replacing fossil-fuel-based heating and processes. As more renewable energy is progressively added to the power grid, the grid itself must take steps to decarbonize. The SF6 greenhouse gas currently has a unique use exemption in insulating medium-voltage (MV) electrical ...

How big is the distributed energy opportunity for water and wastewater utilities?
Energy costs for water utilities are large, and growing Energy is a significant cost for many water utilities, and costs are growing as more energy-intensive forms of water supply, including desalination, are being used. Energy is typically the second-largest utility budget item in developed countries, after labour. In many developing countries, energy can account for 70% or even more, of annual ...

How Energy Storage Can Pave the Way for Renewable Energy Adoption
Introduction Renewable energy offers a hopeful promise to reduce the energy sector’s carbon footprint, but many challenges must be addressed before it can be more extensively integrated into our society. One of the greatest barriers to widespread adoption is quite simply that due to the nature of renewable energy – the fact that it is produced only when solar rays, wind, etc. are ...

The regional analysis of energy consumption and energy resources in China
In recent years, issues relating to Chinese energy supply and consumption have drawn worldwide attention. The Chinese government maintains that the solution to energy demand issues should be resolved by improving domestic supply; but the regional availability of energy is irregular across China. The regional consumption and composition of energy supply are analysed in this paper and suggestions ...

Why 98% of commercial and industrial buildings aren’t getting the most value out of their solar installations
Solar installations at commercial and industrial buildings have soared in recent years, with businesses realizing that they’re smart investments. Part of the reason is that solar installations produce clean, locally generated energy — a must-have in a time of ambitious sustainability goals. But not all solar installations are alike. According to a 2021 study by Berkeley Lab, 98 ...
