The rise of renewable energy means utility companies must change business models

 Missouri S&T – News and Events – The rise of renewable energy means utility companies must change business models (mst.edu)


With the rise of individual households producing surplus power via solar panels and selling energy back to power companies, the profitability of electric companies could drop and lead to acquisitions and mergers. The electric industry has also seen changes in renewable energy integration and regulatory changes that could lead to shrinking profits and firm consolidations.

A researcher at Missouri S&T is studying the hypothetical creation of energy oligopolies, a small group of companies with little competition, in the electricity industry and their chances of remaining profitable through the move to more renewable energy sources such as solar power.

“Our study examines distributed energy resources, which are small-scale and local energy generation units connected to the grid at the distribution level,” says Dr. Mahelet Fikru, an associate professor of economics at Missouri S&T. “These resources such as rooftop solar panels and small-scale wind farms are transforming the electric grid and changing business models by the day.”

Fikru says that these distributed energy resources can help meet energy demand where traditional power supply is low and allow consumers to have access to renewable energy sources, but will have an impact on utility companies’ costs and revenue streams.

In the study, conducted with Dr. Luis Gautier at the University of Texas-Tyler, Fikru includes two sector parameters that may influence profitability – the rate that renewable energy raises grid integration costs and the extent to which renewable energy reduces pollution. Her models predict that an increase in the first parameter reduces the profitability of mergers while an increase in the latter increases mergers.

“We find an increase in energy produced from distributed sources reduces the profitability of profitable mergers and reduces losses from unprofitable mergers,” says Fikru. “The model also shows that the variability in electricity produced from renewable sources encourages utilities to produce more, which in turn magnifies the extent that extra renewable energy affects merger profitability.”

As an example, Fikru says that due to physical constraints of the distribution systems, utilities have to explicitly factor in these individual resources of electricity generation in their future planning and investment decisions. As distributed energy resources become competitive with traditional central electricity generators, utilities will have to change their business models to maintain competitiveness.

Subsidy For Biomass Briquetting Plant Project In India

blog.briquettingpressmachine.com/subsidy-for-biomass-briquetting-plant-project-in-india/ Subsidy for biomass briquetting plant project is the unique feature of this project. The new energy system biomass briquette plant is the great option for need of renewable energy in future. Sustainable energy sources are new expect for future energy sources and that’s why biomass briquetting plant is more preferable in India as well as foreign countries. Government encourages biomass briquette plant project by offering best subsidy plans to buyers. You can find any information of government incentives on biomass briquetting project, here. State Subsidy for  briquetting machine  in India is varies depends upon government taxes. Due to subsidy for biomass briquette plant in India, advantages and profitability of briquetting press machine is great. Being Agriculture country, the current availability of biomass in India is estimated at about 500 millions metric tones per year which is ...

Solar Cell Manufacturers review

There are essentially 3 types of Solar Cell Companies .The tier 1 comprising top 2% do core R&d and are integrated end-to-end.The experience is more than 10 years. The second line about 8% do not indulge in R&d but use partial robotics etc for manufacturing. They have experience of 2-5 years .The rest 90% are assemblers and use human production lines for manual soldering.The projects however have a good capital output ratio .  Here's a good link to review the top Solar Companies  http://www.forbes.com/sites/uciliawang/2014/12/03/guess-who-are-the-top-10-solar-panel-makers-in-the-world/#2e34708f2812 Solar equipment makers are gearing up to expand production again after many of them had to idle production lines or close factories. So who are the top 10 solar panel makers these days? IHS   released its ranking today that put Trina Solar as the top shipper of solar panels in 2014, followed by Yingli Green  Energy . Both companies are based in ...

11 countries leading the charge on renewable energy

https://www.climatecouncil.org.au/11-countries-leading-the-charge-on-renewable-energy/   The need for a swift transition to renewable energy is more urgent than ever. Climate change, driven by the burning coal, oil and gas, is already wreaking havoc on communities, economies and ecosystems right around the world. The easiest, quickest and most effective way of driving down greenhouse gas emissions and giving ourselves the best chance of kicking climate change’s butt is by moving to an energy system based on renewables and storage.  Here are some inspiring countries that are using clever combinations of renewable resources and efficient, targeted policies to drive down their emissions . Sweden In 2012 Sweden reached their target of 50% renewable energy 8 years ahead of schedule. This puts them right on track to reach their 2040 goal of 100% renewable electricity production. How did they do it? By taking advantage of their natural resources and using a com...
