On October 4th, 2018, Leaders in Energy (LE), in partnership with Resilient Virginia, held its “Utilities of the FutureForum” at the US Navy Memorial in Washington DC. The event had over 80 attendees and was an exciting opportunity to look at recent developments in the role of utilities and future of energy provision and new changes.
Electricity markets are complex compared to other markets such as transportation and physical commodities markets, as supply and demand are required to be matched in real time. In addition to this, mismatches in electricity load scheduling can lead to serious consequences such as blackouts. Due to its high social importance, in many countries, the electricity sector was previously owned and operated by state agencies. This has however changed, and many countries have restructured and deregulated their electricity markets. Regulated and deregulated electricity markets have their pros and cons in terms of consumer price, efficiency and environmental impacts. In this article, the case of United States is examined to compare the renewable integration strategies in these two different types of electricity markets. In the United States, the Northeast, Midwest, Texas and California have deregulated market structures while other parts have regulated markets. Currently, 24 states have a deregulated generation sector and 18 of them have deregulation at retail level also.
The United Nations Millennium Summit in 2000 produced 8 Millennium Development Goals (MDGs), designed as a blueprint to improve the lives of the world’s poorest and most vulnerable populations. The MDG target date came and passed at the end of 2015. After analyzing the successes and shortcomings of the MDGs, the UN followed with a set of 17 Sustainable Development Goals (SDGs)—agreed to by 193 countries, including Cambodia—to replace and expand the MDGs, as well as highlight additional areas of global concern. One of these SDGs is the new goal of bringing “affordable and clean energy” to all nations.
In line with this objective, Cambodia’s government has embarked on an ambitious plan to provide reliable and inexpensive energy to its entire population. Cambodia has made great strides in meeting the energy demands of its population. But what remains uncertain are the environmental and social costs of the dams and fossil fuel plants being built. But it is hard to turn down the funding and support in Cambodia’s drive to develop its lagging infrastructure. This is a dilemma faced by the poorest nations—not just Cambodia—as they look for paths to improve the lives of their people. If Cambodia is to move up the economic ladder and attract more international business investment, it needs to continue improving energy access and stability. In rural areas this may mean looking at a combination of on-grid and off-grid solutions. It also needs to protect its valuable resources and look for more sustainable approaches to energy access.

The electrical grid is the largest tangible network created by humankind. It all started in 1880’s, when energy was produced very close to end users, usually big industrial facilities. After 150 years of development, the world created incredible infrastructure to assure electricity supply almost anywhere. Since then, electrical grids have been expanding and embracing more generation units and end-users while covering extensive areas. That pattern, once obvious and most practical, became outdated. Overloaded electrical grids are difficult to maintain, unstable and, in case of infrastructure damage, extremely time-consuming to restore.
On September 20th, 2017, when Hurricane Maria crashed into Puerto Rico, about 95% of the island lost electricity. This energy crisis demonstrated how non-resilient the current grid is. Extreme weather events crippled the entire island. It could have been significantly mitigated - if not avoided - if Puerto Rico had developed independent microgrids. Downscaling the electrical grid by creating dispersed microgrids would increase reliability and resiliency in the electricity supply.
In this day and age, when we can hear a lot of negative news, I wanted to share some positive highlights from a fascinating technical tour that I took on March 7-8, 2018 of the National Energy Technology Laboratory (NETL) and the Longview power plant which uses High-Efficiency Low-Emissions (HELE) technologies. The tour was conducted by the National Capital Area Chapter for U.S. Association of Energy Economics (NCAC-USAEE) to these facilities in Morgantown, West Virginia.
