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.

Moving from VPPs to DERMS: A Global Phenomenon Driven by EVs

By Peter Asmus on May 23, 2019 10:00:00 AM


Guest blogger Peter Asmus of Navigant Research posts this week about the widening use of distributed energy resources around the world, virtual power plants and distributed energy resources management systems.

As distributed energy resources (DERs) continue to proliferate, so do the reliability challenges associated with the world’s aging grid infrastructure. The diversity of resources added to the power grid include plug-in EVs (PEVs) and rooftop solar PV coupled with energy storage devices at residences. As the grid was not designed for two-way power flows, these trends create challenges and opportunities for vendors and grid operators.

Alectra is Building the Business Case for Integrating Microgrids, VPPs and DERMS

By Peter Asmus on Sep 12, 2018 12:59:06 PM

Leading up to a September 17 webinar with Alectra, Navigant and Enbala, Navigant's Peter Asmus provides insights on some of the topics to be covered in the webinar. 

Alectra, the second largest municipal utility in North America, was the first utility to develop a microgrid offering for its customers. It developed a small, commercial-scale microgrid and then a utility-scale microgrid, the latter at its own headquarters at Cityview in Vaughan, Ontario. This utility-scale microgrid integrates a variety of distributed energy resources (DERs) while also featuring the ability to island, if necessary, to maintain reliability at a site that includes Alectra’s center of operations.

This utility-scale microgrid was focused on the internal optimization of these assets to create a reliable optimization network. As Alectra looks out into the future, however, it realizes that it had to build the business case to provincial regulators about why ratepayer investments in control of BTM assets provided value to all distribution network ecosystem stakeholders, including those with DERs and those without.

Two Sides of the Same Coin: How Enbala and Alectra Are Pushing the Energy Cloud Envelope

By Peter Asmus on Aug 23, 2018 8:40:11 AM

Guest blogger Peter Asmus of Navigant Research posts this week about virtual power plants, distributed energy resources management systems, microgrids — and the way in which Alectra is bringing them all together to meet its customers energy needs and its own grid reliability requirements. 

Electricity is a multidimensional product that requires constant fine-tuning. Otherwise, the lights go out, resulting in substantial lost economic activity. The challenge of accomplishing this task has become increasingly difficult as the fleet of distributed energy resources (DERs) begins to take over electricity resource pools. Beginning in 2018, annual centralized power resources began to give way to distributed generation and a more diverse DER mix. I noted last year that this transition was likely.

Taking VPPs to the Next Level

By Peter Asmus on Jun 21, 2017 9:10:00 AM

This week, we feature guest blogger Peter Asmus of Navigant Research, who talks about virtual power plants (VPPs) and their changing role in the utility industry.

The primary goal of a virtual power plant (VPP) is to achieve the greatest possible profit for asset owners—such as a resident with rooftop solar PV coupled with batteries—while maintaining the proper balance of the electricity grid at the lowest possible economic and environmental cost. The purpose is clear, but getting to this nirvana is not easy. Nevertheless, there are clear signs that the VPP market is maturing. New partnerships are pointing the way for control software platforms that can manage distributed energy resources (DER) in creative ways.
