What's Coming? The Power of Distributed Energy in a Modern Grid

By Bud Vos on Jan 5, 2017 11:30:00 AM

It’s a new year, folks, and time to learn from the ups and downs of the previous 12 months and set a course for a successful 2017.  We spent some time at the end of 2016 working with Edison Foundation’s Institute for Electric Innovation (IEI) on a book titled “Thought Leaders Speak Out: Key Trends Driving Change in the Electric Power Industry.”  Enbala’s contribution was a chapter exploring the future of distributed energy in a modern grid.

The U.S. election is finally over, leaving some elated and others terrified. The last several months have been polarizing and contentious, and many feel that a Trump presidency is destined to bring uncertainty to the energy industry and endanger the goal many of us share of a more sustainable energy future.

Here are my thoughts on the key reasons why I believe that the distributed energy resources (DERs) market will continue to thrive, along with the march towards an advanced energy economy.

Mix ‘n’ Match DERs

By Enbala on Nov 4, 2016 10:30:00 AM

Right now, analysts see enormous growth ahead for solar-plus-storage systems. A report by IMS Research forecasts the market for storing power from solar panels – which was less than $200 million in 2012 – to reach $19 billion by 2017. And, it’s easy to see why.

After all, rooftop solar panels are more valuable to people if they can store the excess energy produced and prolong the benefits of the on-site generation capacity. Plus, the flexibility of battery energy storage makes it truly valuable. With a quick response time and precise controllability, batteries can provide a wide set of grid services, so they can deliver value to multiple participants in the power system, including end-use customers, distribution utilities and wholesale market operators.

Distributed Energy Resources: The Energy Efficiency Story

By Ginger Juhl on Oct 5, 2016 10:30:00 AM

Today, October 5, is the inaugural Energy Efficiency Day 2016, and the perfect time to talk about what we are doing - in conjunction with our customers - to reduce traditional energy consumption and make the world a better place for ourselves, our children and our children’s children.

Energy Efficiency Day is a collaborative effort of regional and national organizations working to promote energy efficiency, including many that we strongly support. This includes the American Council for an Energy-Efficient Economy (ACEEE), Advanced Energy Economy, the Regional Energy Efficiency Organizations, Appliance Standards Awareness Project, E4TheFuture, Natural Resources Defense Council, and a very long list of cities, utilities, universities, associations and companies like ours who share a common mission with sustainability at its core. You’ll see most of us writing, tweeting and otherwise sharing our energy efficiency stories today – stories about using better technology and practices so that less energy is consumed to accomplish the same tasks, while continuing to keep homes and businesses comfortable.

Three Best Practices for IT/OT Convergence in a Distributed Energy World

By Malcolm Metcalfe on Sep 29, 2016 1:29:20 PM

Ten years ago or so, when utility workers first started talking about IT/OT convergence, conversations revolved around the wealth of data streaming into utility offices from advanced metering infrastructure and remote sensors.

With AMI, for instance, utility engineers could suddenly see consumption in 15-minute increments, allowing them to leverage that data for things like load studies and distribution-system transformer sizing. Utility managers could use the blink counts from advanced meters to direct tree-trimming crews, letting them know there was a pretty good chance wayward branches were causing momentary outages on a feeder. Or, they could use the last-gasp signals to more quickly triangulate an outage and dispatch restoration crews more efficiently.

IT/OT convergence is what happens when IT and OT drop the silo walls to unite systems such as outage management with front-end, field technology like advanced meters or distribution system assets. But, IT/OT convergence has begun to expand as generation assets begin to proliferate behind the meter, and IT systems will be needed to help accommodate and control these assets. The convergence is becoming more complex and all-encompassing, so here are a few pointers for utility mangers to keep in mind.

DERMS: Coming Soon to Your Utility’s IT/OT Convergence

By Malcolm Metcalfe on Sep 8, 2016 1:38:22 PM

Last year, analysts at Gartner placed IT/OT convergence on their Top-10 list of trends affecting the utilities industry. Actually, it’s been in progress for nearly a decade but, now more than ever, IT/OT integration looms as a crucial utility move. What’s more, it is factors outside utility walls that are rousing such urgency. What are they? Look around your neighborhood. If you see a lot of rooftop solar panels, some of those factors are sitting right in front of you.

What’s more, GTM Research forecasts a 94 percent increase in new PV installations in the U.S. during 2016. Worldwide, Navigant Research says, “Annual installed capacity across the global distributed energy resource (DER) market is expected to grow from 136.4 GW in 2015 to 530.7 GW in 2024, representing $1.9 trillion in cumulative investment over the next 10 years." 

What does this have to do with IT/OT convergence?

Spock or Scotty: Which character fits your organization?

By Enbala on Aug 29, 2016 10:00:00 AM

Raise your hand if you sometimes feel like Mr. Scott from the original Star Trek series, frantically trying to keep the engines roaring while the ship takes one phaser hit after another: If you did raise your hand, you’re not alone. There are plenty of reasons utilities might be playing the Mr. Scott role.

One is under investment in infrastructure, which was named as the top concern by 47 percent of utility executives who answered a Utility Dive survey late in 2015. Another is what the California Independent System Operator calls the Duck Curve. It shows how behind-the-meter solar installations are creating daytime over-generation on the California grid and, because rooftop solar quits generating power about the same time people come home and start using more of it, there are steep ramps at the end of the day.

Demand response programs could help utilities deal with these issues. But, utilities that are doing simple demand response are kind of like Star Trek’s Scotty. They’re just getting by, handling one crisis after another, giving it all she’s got, Captain. “I don’t think she can take any more!”

Load, the oft-overlooked distributed energy resource

By Enbala on Aug 17, 2016 2:00:00 PM

INTRODUCTION:

Researchers at DNV-GL did a fine report for the New York Independent System Operator a few years ago. Titled A Review of Distributed Energy Resources, it offered this definition of the various distributed energy resources (DERs) examined in the report:

“… DER technologies are defined as ‘behind-the-meter’ power generation and storage resources typically located on an end-use customer’s premises and operated for the purpose of supplying all or a portion of the customer’s electric load. Such resources may also be capable of injecting power into the transmission and/or distribution system or into a non-utility local network in parallel with the utility grid. These DERs include such technologies as solar photovoltaic (PV), combined heat and power (CHP) or cogeneration systems, microgrids, wind turbines, micro turbines, back-up generators and energy storage.”

Granted, the research team did acknowledge that some sources – including the New York Public Service Commission – included customer load in its list of DERs, but load wasn’t one of the DERs covered in the report. That’s too bad because load can hold its own against other DERs for a variety of grid-supportive purposes.

Fight, flight or innovate: How will utilities deal with DERs?

By Malcolm Metcalfe on Aug 3, 2016 4:06:42 PM

INTRODUCTION:

Fight or flight may be the two most common reactions mammals have when facing a threat, but for utilities that perceive distributed energy resources (DERs) as risky to business, there’s another option: innovate.

The rapid pace of disruption

Tony Seba, a clean-technology thought leader, author and Stanford University instructor, believes that the age of what he calls “participatory energy” – user-centric generation, storage, management and energy-market participation – will eclipse the utility-centric model of today by 2030.
