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.

INTRODUCTION:

Raise your hand if you’re a utility professional or grid operator planning to make some significant infrastructure investments in the next few years. You won’t be alone.

After all, energy infrastructure in the U.S. earns a D+ from the American Society of Civil Engineers (ASCE). If you went to the ASCE report card, you’d see some mighty big numbers associated with the transmission and distribution spending that will likely be needed by 2020 to fill the investment gap, which is the difference between what’s needed and what’s planned.
