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.

Global Virtual Power Plant Market Trends

By Lana Gonoratsky on Jul 30, 2019 11:22:00 AM

Energy systems are changing. As variable renewable energy generation replaces retiring fossil fuel-run power plants, we see a shift from our century-old mindset of centralized supply following demand, to a more distributed grid with distributed energy resources (DERs) playing an essential role in a sustainable energy future. In order for renewable energy resources and DERs to replace conventional power plants, they need to be able to act like power plants – virtually at least.

At technology and innovation’s finest hour, we are able to aggregate disparate, geographically dispersed DERs and orchestrate them in such a way that they are able to respond to the grid’s needs at the same speed and accuracy as a traditional power plant. That’s where the Virtual Power Plant (or VPP for short) comes in. Navigant Research defines a VPP as:

“… a system that relies upon software and a smart grid to remotely and automatically dispatch retail DER services to a distribution or wholesale market via an aggregation and optimization platform”

VPPs are critical for the transition to more sustainable energy systems – so where is the technology at? Where can we find VPPs? And what can we expect in the future?

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.

Virtually There: From DERs to VPPs

By Deborah Hazebroek on Oct 26, 2018 11:23:52 AM

At this year’s GridFWD conference delegates met for the first time in beautiful Vancouver, British Columbia, home of our Canadian headquarters. Enbala was present in full force, as a sponsor, panelist and moderator. The well-attended event covered a range of pertinent and enlightening topics including grid modernization and decarbonization.

 One such discussion, moderated by Graham Horn, Enbala’s VP, Business Development, focused on the path from DER grid presence to VPP flexibility. Graham was joined by Jeremy Twitchell, Energy Research Analyst with Pacific Northwest National Labs (PNNL), J.P. Batmale, Division Administrator at the Oregon PUC, and Smriti Mishra, Strategic Partnership Manager with National Grid.

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.

Can DERs Play Too?

By Deborah Hazebroek on Jul 18, 2018 2:06:59 PM

The Question

The world is changing. This isn’t news, of course. In fact, it’s rather old news – the world has changed. And the composition of the power grid has changed along with it. More roofs have solar panels. More garages house electric vehicles. The devices consumers plug into outlets have radically different load profiles than the devices of previous generations. Today there is an increased prevalence of wind farms, smart inverters, batteries and many other distributed energy resources (DERs) at the grid edge.

All these DERs offer tremendous potential through control and optimization. But while this capability presents copious opportunities, it also creates a few headaches, particularly for grid operators, often miles away (literally and figuratively) from where the DERs are located.

Yet DERs are becoming so entrenched in the daily operations of the grid that it’s tempting to ponder just where their limitations lay. With advancements in technology and business models, many innovators are looking to increase value from DERs, which leads to the latest question surrounding the capabilities of these assets: Can DERs play in utility and wholesale markets?

ELECTRIC VEHICLES – good for our roads, good for our lungs, but good for our grids?

By Lana Gonoratsky on Jun 20, 2018 9:26:00 AM

I take the bus to work. On any given weekday, you can find me waiting on the side of a road while vehicles of all shapes and sizes whiz by, leaving behind a trail of noise and exhaust. It would be all well and good if this was just another weekday annoyance that could be easily shrugged off, like a fresh pile of snow blocking the sidewalk or a texter blissfully skipping the line at a busy coffee shop. But that’s not the case. Vehicle exhaust is a known pollutant that significantly affects human health and the environment. Regulators put limits on emissions – but these generally focus on new car sales, and then they can still be tampered with. So as a commuter waiting at the side of a busy road, I don’t feel too reassured. But, when I see that clean technology goals for electric vehicles are on track, hear announcements from companies like Tesla, Thor and Volvo electrifying trucking fleets, and read about commitments by governments to support these efforts, I do feel hopeful.

Changing to Clean Energy

By Malcolm Metcalfe on Mar 19, 2018 12:48:34 PM

Introduction

Science has told us that we must reduce carbon emissions if climate change is to be kept below acceptable limits. The transition has led us in many new directions. Most politicians outside the US believe that our energy supply must be based entirely on renewable energy. This alone creates a large issue, in that the electric grid supplies less than 20% of total energy needs. The proposal to replace all fossil fuel with renewable capacity would require a potentially large increase in grid capacity. Ironically, many politicians typically include nuclear generation among the sources to be eliminated. The one bit of good news is that the efficiency of electrical devices is often better than fossil fuel, and the existing grid operation using a generation following load approach results in a system that can deliver more energy.

The results to date have been frustrating, both in costs and performance, and there are many serious problems that may make a complete conversion very difficult. These challenges include a lack of grid and generation capacity to handle the added electrical load, as well as the operation of the existing grid with extensive distributed devices.
