TENET #3 – ACHIEVING LONG-TERM GOALS REQUIRES UNLIMITED SCALABILITY

By Michael Ratliff on Sep 26, 2017 8:50:00 AM

REDEFINING SUCCESS FOR A DISTRIBUTED ENERGY GRID: THE THREE TENETS

In our first “Three Tenets” blog we talked about the importance of speed when it comes to effectively leveraging distributed energy resources (DERs), and in the second one we wrote about the importance of accuracy. In this one we add a third dimension of criticality – scalability. From our perspective, these are by far the top three critical success factors today when it comes to successful DERMS and VPP projects and the determining factors for the long-term viability of these projects as increasingly larger numbers of distributed energy assets find their way onto the grid. There are, of course, other important factors, but many that topped the criteria list during the early phases of DER adoption have been far overshadowed in today’s world by the need for the triumvirate combination of speed, accuracy and scalability.

Could Virtual Power Plants Make Utilities the Uber of Distributed Energy Resources?

By Enbala on Sep 8, 2017 2:44:59 PM

It’s been said that analogy is a powerful force when it comes to innovation. It creates an environment where it’s easier for people to apply knowledge from one domain that they already understand to another that they don’t understand quite as well and thus make it, too, easier to grasp. 

Uber is a prime example of analogy taken, perhaps, to the extreme. It would be tough to estimate the number of companies that have come into being recently aiming or claiming to be the “Uber for ....” you fill in the blank. There’s an “Uber for errand running,” an “Uber for pet care,” an “Uber for tool rental,” an “Uber for grocery (and alcohol) delivery,” an “Uber for finding parking spaces…”  You get the picture.

Efficiency and Cooperation

By Malcolm Metcalfe on Aug 16, 2017 8:03:00 AM

I have posted several blogs in the past few weeks, focused on the potential to improve the operation of the electric power grid, reducing losses, and driving the overall efficiency up. Some of the thoughtful comments that have been posted by readers have provided food for thought. One comment was particularly important to this discussion…

“What’s best for players individually is not what’s best for the public and for the system as a whole.”

This comment reveals an issue that may soon be a problem.

For most of the 130-year history of the electric grid, utilities have charged residential customers for energy used and have NOT charged for peak power demand, as they do for commercial and industrial accounts.

TENET #2: NEW FRONTIERS IN DER ACCURACY

By Michael Ratliff on Aug 10, 2017 8:30:00 AM

REDEFINING SUCCESS FOR A DISTRIBUTED ENERGY GRID: THE THREE TENETS

When it comes to effectively leveraging distributed energy resources (DERs), there are three critical success factors that any DER management system or Virtual Power Plant (VPP) must embody. In a previous blog we focused on Tenet #1: the importance of speed.  

In today’s blog, we address another of the top three criteria: accuracy. Just as the question “how fast is fast enough” was answered with “it depends,” so too does the question “how accurate is accurate enough” have the same response. The criticality of accuracy depends on what the distributed energy resources are being dispatched to do.

The Grid Needs a Symphony, Not a Shouting Match

By Enbala on Jul 20, 2017 3:45:24 PM

Our blog post this week was authored by our friends and fellow Coloradans at the Rocky Mountain Institute (RMI). We think it's one of the best posts we've read in a while, and RMI kindly gave us permission to share it. 

In April, U.S. Secretary of Energy Rick Perry announced a 60-day study on electricity market design and grid reliability, meant to assess to what extent current market designs fail to adequately compensate “baseload” (i.e., coal- and nuclear-fired) power plants.

The memo commissioning the study presents as “fact” a curious claim: “baseload power is necessary to a well-functioning electric grid.” This notion has been thoroughly disproven by a diverse community of utilities, system operators, economists, and other experts that moved on from this topic years ago. To these practitioners, this premise seems as backward as if President Eisenhower, instead of launching the interstate highway system, had called for restudy of the virtues of horse-drawn carriages.

Today, the grid needs flexibility from diverse resources, not baseload power plants. Leveraging market forces to help us decide between options offers the best chance of avoiding the multitrillion-dollar mistake—and gigatons of carbon emissions—of blindly reinvesting in the past century’s technologies.

TENET #1: FASTER THAN A SPEEDING BULLET

By Michael Ratliff on Jun 26, 2017 12:45:00 PM

REDEFINING SUCCESS FOR A DISTRIBUTED ENERGY GRID: THE THREE TENETS

When it comes to effectively leveraging distributed energy resources (DERs), there are three critical success factors that any DER management system or Virtual Power Plant (VPP) must embody. This is especially true as the number of distributed energy assets continues to grow and as the ways in which distributed energy can be used to keep the grid in balance grows along with them. They are: 

  • Speed
  • Scalability
  • Accuracy

In this blog, we tackle the topic of speed and exactly why this such an important success criteria.

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.

Virtual Power Plants and the New Energy Future

By Enbala on May 25, 2017 1:05:15 PM

IN CASE YOU MISSED IT:

Virtual power plants or VPPs are one of the hottest topics in the energy industry today. In fact, investments in VPPs are expected to total over $68.6 billion by 2025 -- this according to Navigant Research, who has published a new white paper on the topic. 

Software advancements are enabling greatly expanded capabilities in the distributed energy resources (DERs) that can be aggregated into VPPs, which are now capable of responding to the needs of the power grid at the sub-second speeds required for instantaneous grid balancing. 

Titled Stacking Values with Virtual Power Plants in Today's Digital Power Grid: Moving Distributed Networked Energy Into the Mainstream, the paper was authored by Navigant's Peter Asmus and covers:

  • The expansion and convergence of VPP market segments
  • New distributed energy resource architectures
  • Physical VPP grid and market interaction values
  • ROIs on VPPs

A commentary on the FERC NOPR to Integrate More DERs into Organized Markets

By J.T. Thompson on May 9, 2017 8:00:00 AM

Opening the Distributed Energy Doors is a Win-Win

In November of last year, FERC issued a Notice of Proposed Rulemaking (NOPR) around electric storage resources. The goal was to better allow these distributed energy resources (DERs) to compete in the various wholesale markets.  Per their November press release, FERC’s NOPR would require that RTOs/ISOs:

  • Establish a participation model consisting of market rules that, recognizing the physical and operational characteristics of electric storage resources, accommodate their participation in the organized wholesale electric markets
  • Define distributed energy resource aggregators as a type of market participant that can participate in the organized wholesale electric markets under the participation model that best accommodates the physical and operational characteristics of its distributed energy resource aggregation

Disrupting the Status Quo…  Thinking Out of the Box

By Malcolm Metcalfe on May 4, 2017 8:58:22 AM

A few days ago, I listened to a group of environmentalists on the evening news protesting a plan to build a new bridge that would solve traffic congestion and make it easier for people get in and out of a local large city. The protestors wanted the money spent instead on public transit, claiming that this options had not even been examined, and arguing that their solution would solve the transportation problem without requiring construction of new infrastructure.

I looked more closely at both alternatives. The government and the consultants retained to propose solutions to the problem had advanced several standard options, all of which revolved around either a bridge or a tunnel, while the environmentalists had extended the options by one – adding public transit as a means to achieve a similar result.

This seemed logical until I started thinking about the need to add one other criteria to the equation: the need to reduce carbon emissions.
