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.”
