Reliability


I hear a lot of talk about a great desire to include renewable energy into the national energy mix, if it weren’t for the issue of intermittency. Sure, we can control the costs to build a wind farm or a solar plant, but the fuel supply is truly in the hands of Mother Nature whenever she decides to make the wind blow or the sun shine.

As the CEO of a renewable energy company with more than 500 MW of wind and solar installed in North America, I know we only build renewable energy projects in areas with the best wind or solar capabilities within a given market. But still, it is not possible to know exactly when Mother Nature will smile on us. Unfortunately, this challenging characteristic of renewable energy has become the foremost excuse for utilities to restrict or block the addition of renewable energy resources to our energy mix. I would argue that intermittency itself is not the immediate issue for utilities, but rather how they are looking at the larger energy pool in total. Instead of focusing on intermittency roadblocks, utilities need to consolidate into more modern and broader markets that diversify management of the intermittency issue and ensure competitive access to the power grid.

The industry of substation automation, involving a multitude of devices, technologies, and business models requiring skilled product selection, implementation, interoperability, and engineering, is burgeoning. Committed Smart Grid nations are prioritizing their efforts to revitalize their decaying electric infrastructure by investing in critical upgrades to their substations and ensuring these structures can be seamlessly connected to the Smart Grid.

SBI Energy report “Global Smart Substation Products Market” examines the avid worldwide interest in smart substation development, including the market size, scope of the products and the uneven pace at which nations are adopting the different substation automation architectures. Keep reading →


“The results from these case studies demonstrate that variability needs not be an impediment to deployments.”

“As long as power systems and markets are properly configured so they can get the best use of their flexible resources, large shares of variable renewables are entirely feasible from the balancing perspective.” Keep reading →


The US military has long been viewed as a source for technological innovation. Inventions, from airplanes to computers, were tested in initial phases for military use.

This time around, the US military may be leading the way in energy efficiency technology. Keep reading →

The future of nuclear energy post-Fukushima is a major outstanding question in the energy industry.

The need for reliable, large-scale electricity generation to replace steadily-retiring coal units and aging nuclear plants is obvious, and until earlier this year nuclear seemed like the best option. Keep reading →


The electricity grid of the future needs to be flexible in order to integrate growing use of renewables, a new book from the International Energy Agency (IEA) says.

In Harnessing Variable Renewables: A Guide to the Balancing Challenge, the agency uses case studies of eight geographic regions, each facing unique energy challenges, to develop a four-step Flexibility Assessment (FAST) method. Keep reading →

Representatives for two groups of power generators were sharply divided over the federal government’s plans for reducing emissions of mercury and other toxics from power stations.

At a Philadelphia hearing on the Environmental Protection Agency’s proposals for limiting emissions from coal- and oil-fired power plants, the spokesmen presented dramatically different views on whether the plans are financially and technically achievable or are the result of flawed analysis that overstates economic benefits and imposes heavy costs on the industry.

With its latest new product announcement, globe-spanning conglomerate GE is trying to solve several of the electricity sector’s most pressing challenges at once.

The new FlexEfficiency 50 Combined Cycle Power Plant design was announced today in Paris, amid claims that the unit’s ability to quickly cycle up to full power and operate at a very high 61% operating efficiency make it a game changer in the industry. Keep reading →


Coal remains the workhorse of the US electricity sector, but its future is murkier than ever.

The industry has been on a campaign for nearly a decade to educate Americans about the extent to which their electricity comes from coal, but have had difficulty turning that into a wider recognition of the contributions comparatively cheap power have made in boosting US economic performance.
