The European Take on Virtual Power Plants

By Peter Asmus on Dec 12, 2019 9:30:00 AM

Guest blogger Peter Asmus of Navigant Research writes about the virtual power plant market in Europe. 

Europe, considered the birthplace of the virtual power plants (VPPs), is pushing the envelope on the concept. The continent is adapting platforms to provide new and more sophisticated capabilities to maximize the value of flexibility resources while opening doors to new value streams linked to creative ancillary service markets and real-time energy trading.

Historically, the European VPP market has centered on renewable energy integration. While this remains the case today, a shift is underway to learn from other evolving VPP markets in Canada, Australia, and Japan. The new focus includes integration of demand side resources as well as energy storage and EVs. Today, virtually anything that produces, consumes, or stores electricity (or energy) is a candidate for VPP inclusion.

Postcard From the Future: VPPs in Australia

By Peter Asmus on Sep 25, 2019 12:30:37 PM

Guest blogger Peter Asmus of Navigant Research writes about the evolution of the virtual power plant market in Australia. 

Australian consumers boast one of the highest per capita consumption rates of electricity in the world (even greater than the U.S.). These consumption levels translate into flexible load resources ideal for aggregation and optimization into virtual power plants (VPPs).

What is a VPP? Think of it as a conglomeration of many distributed energy resources (DERs -- loads, but also generation, batteries and electric vehicles -- that can be combined into a pool whose sum of parts’ value is far larger than these DER assets offer individually. With sophisticated artificial intelligence software, these resources scattered across the grid can be combined “virtually” to provide the same services as a traditional 24/7 power plant -- but at much lower and environmental cost.

Japan Could Determine the Fate of the World Market for VPPs

By Peter Asmus on Jul 16, 2019 9:04:00 AM

Guest blogger Peter Asmus of Navigant Research posts this week about the vast potential for virtual power plants and distributed energy resources in Japan. 

The first solar PV cell made in Japan was in 1955; the first solar PV panel was connected to the Japanese grid in 1978. Japan emerged as the global leader in solar cell production in 1999 and then solar power generation in 2004. Though solar PV provided only a small portion of Japan’s overall energy supply, it showed that the country’s regulators were investigating distributed energy resources (DERs) well before other markets globally.

Japan is at a crossroads. How does one leap into the future epitomized by the concept of the Energy Cloud while simultaneously maintaining the centralized generation status quo?  The country is exploring how virtual power plants (VPPs) can help straddle this chasm, serving as a bridge from the past to the future.

Adding PV to the grid: It takes more than firming

By Enbala on Oct 19, 2016 9:20:00 AM

If you’re like most people who’ve gone to a conference lately – or read this blog from its inception – you’ve already heard warnings about what could happen to grid voltage and stability when stray clouds waft over neighborhood solar arrays and block PV generation. The sudden drop of renewable power is what many people point to as the key challenge of variable generation resources.

After all, that’s why utilities are looking for ways to “firm” renewable generation, which is the process of backing variable resources up with some combination of fast-ramping power or demand-side management to jump in when power production subsides. But, while loss of power gets most of the attention, over-production is an equally daunting challenge for grid operators.

Smarter solar: Go West!

By Bud Vos on Nov 18, 2015 6:44:41 PM

Anyone who’s seen the California ISO “Duck Curve” knows south-facing roof-top solar is not particularly good for utilities. The problem, which appears so clearly in the eloquent graph below, is that daily peak continues to grow, so utilities still have to build out new generation, transmission and distribution facilities. But, household solar reduces overall energy sales, and this is where most of the money comes from to pay for the new capacity. Some utilities are referring to this as the “death spiral.”
