The Next Generation of DR is limited needs for DR.

Introduction and background:  For Power companies, Demand Response - paying customers to shed load as summer demand needs require -  has been used for many years.

The information presented here is not about downplaying or questioning the use of demand response.

It is about asking if capabilities to provide permanent electricity reductions, Demand Management (DM), would be considered of value for managers of electricity company providers?

This opportunity is the subject of this article.

Part A: Summer Demand needs and Demand Response (DR) Basics

Summer Demand - increased needs for electricity during hot summer months - represents significant and continued challenges for electricity power companies.

Using data from previous summers and analytical techniques, potential summer demand 'hot spots' are identified including estimates of expected KW loads.

With agreements by customers to 'shed load' at several types of notice, Demand Response, the power company manages summer demand.

Customers are paid for their commitments to Demand Response programs and are also paid by the size of the load shedding that they provide.

Living in NY Con Ed territory and being an active NY Con Ed "Participating Contractor", we have seen several annual DR reports.

We interact with several U.S. electricity power companies and we have seen the expenditures that may be needed for their summer demand needs to be met with Demand Response.

The financial costs of Demand response can be tens of millions of dollars within a state and over one billion dollars total nationwide.

##### 

For all its use nationwide, Demand Response (DR) provides band-aids - temporary load reductions - as needed and called for by the power company.

##### 

Part B: Summer Demand needs and Demand Response (DR) Sources of Demand

We recognize that summer demand presents a variety of challenges.

To be able to plan and consider solutions, we need to ask:
                       What are the major contributors to summer demand?

For our purposes here, the major contributors to summer demand are Air Conditioning (A/C) and Refrigeration systems used by Business customers of electricity providers. Also known as Three phase alternating current users.

Please see Note 1 below: Business or commercial & industrial customers compared to residential power company customers. 

The Future of Demand Management and Demand Response (DR)  - A New Scenario

Even knowing the contribution to summer demand of power company business customers' A/C and refrigeration systems, is there now or has there been a reason to inventory business customers' A/C and refrigeration systems, the sources of summer demand?

There has not.

There has not been an energy efficient device capable of reducing electricity for these applications.

The Future of Demand Management and Demand Response (DR):
 
                      A New Scenario - "Intelligent Motor Controllers"

Introducing a family of "Intelligent Motor Controllers" designed to work with business customers' air conditioning and refrigeration systems.   

These motor controllers are sized and installed at the customer air conditioning and or refrigeration application site.   Once installed, the electricity reductions of 25% are permanent.

Where demand response is temporary, the motor controllers provide Summer Demand management - the electricity reductions are continuous.

Please see Note 2 below: Additional applications available with these Motor controllers

Please see Note 3 below: Graphic of motor controllers

The Future of Demand Management and Demand Response (DR):-
 
       The New Scenario - "Intelligent Motor Controllers" - How applied and where

As discussed above, up to now there have not be reasons for power companies to have and manage inventories of their business customers' air conditioning and or refrigeration applications. 


For every U.S. electricity provider, and every one of their customers, whether Business (or Commercial and Industrial) or Residential, their electrical service source can be traced back to an "Area Substation".

As the motor controllers being introduced here work at the customer application site, and each customers electrical application is sourced back to an area substation, it is at the area substation that there are now compelling reasons for power companies to inventory three phase air conditioning and refrigeration systems.

As discussed above, using data from previous summers and analytical techniques, potential summer demand 'hot spots' are identified including estimates of expected KW loads.

These 'hot spots' are a power company area substations.

An area substation if it has and or is expected to experience excessive summer load, summer demand, it will be the focus for our new demand management scenarios and inventories.

Area substations with histories of excessive summer demand and at or near capacity would also be identified and be high priority for inventories.

Having an inventory and being able to measure expected summer demand, as motor controllers are installed and the electricity reductions of 25% measured, needed demand reductions can be monitored and show progress to reduced electricity goals. When a motor controller is installed, the electricity reductions are continuous and permanent. Whenever daily summer demand management needs exist, the electricity reductions will be there.

As the motor controllers are installed, electricity reductions will reduce summer demand levels and reduce demand response needs and costs.

Motor controller installations can also be determined and planned that will increase capacity for customer installations at the area substation.

Benefits for management

  • Managed Inventories and management of summer demand needs.
  • Actual electricity reductions to assess reduced Demand Response needs and costs.
  • Management  now available at area substation to project increased area substation customer capacity.

Smart Grid capabilities provided

Our motor controllers provide smart grid capabilities: reduced electricity usage, reduced start-up spikes and soft-start capabilities. Reduced KW reduces KVAR, and enables Power Factor corrections for the power company grid.

Reduced electricity usage provides extended motor life.

There are communications capabilities that would enable motor controller operations to be monitored at facilities and locations determined by the local power company.

    Detail Column descriptions below example

Depending on the size, number of customers and application type at an area substation,
     Three phase demand reductions may also help manage single phase summer demand needs.

  Additional application types supported by our motor controllers will also see electricity reductions.
      Agriculture refrigeration systems, oil field pump jacks and factory and industrial applications.

We can help:

If you are a company that provides electricity and would like to discuss ways to manage Summer Demand needs: please contact us. We can provide assistance so that your people understand the part played by your area substations customer base. There may be questions regarding the inventories suggested here and how they will provide the tools to manage summer demand.

We can  discuss the roles played by electricity usage Summer Demand challenges with three phase Air Conditioning (A/C) systems and or three phase refrigeration systems and how our Motor Controllers will provide Summer Demand reductions and reduced DR, Demand Response, costs.,

If you are a company with known concerns about the electricity usage costs with three phase Air Conditioning (A/C) systems and or three phase refrigeration systems, please contact us: we will discuss your needs and application installations and suggest actions to get you started reducing those electricity costs.

Please see note 3:  Graphic of the motor controllers

Please see note 4: About us

Note 1: Business or commercial & industrial customers compared to residential power company customers.

In the U.S. Business, also known as Commercial & Industrial power companies customers receive Three phase electrical service with rates different from residential  customers including usage and demand charges.

Residential customers receive single phase electrical service with rates that typically include only usage charges. These services are part of the homes, townhouses and retail units for homeowners and renters.

Note 2: Additional applications available with our Motor controllers include a variety of industrial and factory applications as well as escalators and single motor elevators.

While our focus here are air conditioning and refrigeration systems, a variety of factory and industrial applications use significant KW and may contribute to summer demand issues and load concerns all year.

These applications include conveyors, pulverizors, metal machining and manufacturing presses, wood working, plastic injection molding, and more, will also see reduced electricity usage.

For states with agriculture applications, there are typically refrigeration needs that can see electricity reduced.

For states with Oil Field Pump Jacks usage, electricity reductions are available.

On a pretty serious note - which initiatives has been taken to plant trees in those areas where the summers are too hot? Anyone who has experienced how it is to walk in under the crown of any tree during a hot day, will know that the temperature shift under huge trees can be as much as 5 to 7 degrees of Celsius. 

If you take a trip to the forests, on a typical hot day with 30 degree of Celsius outdoor temperature - you can measure as low as 22 degrees of Celsius inside the forest if the canopy's are tightly joined... 

Try to do the BTU calculation - massive tree planting would also have other side effects such as increasing the humidity, causing more rainfall (when we discuss magnitude of scale...), and anyone who have ever calculated BTU for A/C systems knows that every degree counts...

Sincerely

David Svarrer

DMotor controllers sound like a nice product, however your perspective on DR is too limited and very misplaced.  The direct control programs you cite were always intended to be prototypes for much more all inclusive automated customer directed price-responsive options.  DR under price response provides capability to address all customer loads (residential, commercial and industrial) as well as most utility supply and demand conditions, including renewables.  The California statewide price responsive pilot successfully helped prove this capability back in 2001, however characteristic of the industry, misguided regulatory and political inertia once again prevented progress.  With automated price response DR still has a very good future.

Hi Roger:

DMotor controllers sound like a nice product, however your perspective on DR is too limited and very misplaced

Our Motor Controllers, not DMotor, represent proven technologies used worldwide for ten (10) years. More than a 'Nice product' they can and will deliver significant three phase, Business customer KW reductions and significant reductions in Demand Response costs. The reductions are permanent, once a motor controller is installed, the three phase air conditioning and refrigeration application will see permanent reduced electricity usage.

****

The direct control programs you cite were always intended to be prototypes for much more all inclusive automated customer directed price-responsive options

Until now, no one has known about these motor controllers.

DR under price response provides capability to address all customer loads (residential, commercial and industrial) as well as most utility supply and demand conditions, including renewable.

DR under price response is a band aid, an expensive one. Commercial and industrial demand load management needs can be handled with our motor controllers. They will reduce Demand, KW, lower customer electricity costs and reduce the needs for expensive Demand response solutions.

****

With automated price response DR still has a very good future

Any DR in the future will be of limited needs.

Here's a PLMA pitch: Read all about how DR is evolving at www.peakload.org/DefiningEvolutionDR which PLMA published in 2016 and followed this year with the Future of DER Compendium at www.peakload.org/assets/resources/PLMA-Future-of-DER-Compendium.pdf.  PLMA also produces training course which would help you and others get up-to-(variable)speed on what you've missed about how DR is evolving beyond motors.  Check out www.peakload.org/demand-response-training

Ed:

Please envision our What Is the Future of  DR article Included and integrated into PLMA's    The Future of  Distributed  Energy Resources           www.peakload.org/assets/resources/PLMA-Future-of-DER-Compendium.pdf  with our illustration of a power company Area Substation.

Now consider please, power companies doing preliminary inventories for three phase A/C and refrigeration applications. 

 See *** below  additional application devices supported.

Now they measure some existing units without and with our motor controllers.

What do they find: Significant opportunities to reduce KW 25% whenever the motor controllers is installed. And very happy customers who get direct benefits from reduced electricity costs.

*****  DR Costs

Nowhere in the materials you suggested that I review, do I see discussions of the costs of Demand response (DR) by state, by power company, etc.

I suggest that this is a serious omission on your part,  especially as these expenses are in the Tens of millions of dollars with large power companies, can be over $500 million for large states and billions of dollars nationally. 

***** 

Why don't you and I plan a phone call and we can go over the Area Substations opportunities and value of inventories now that we know our motor controllers can and do reduce electricity usage.

Nowhere in the materials you suggested that I review, do I see any evidence of consideration of  inventories of three phase, business, significant sources of Demand - air conditioning systems and refrigeration systems - and estimates of electricity reductions now available with our motor controllers.

And what else, significant reductions for the need on Band-aid expensive Demand Response (DR) Resources.

The motor controllers provide Demand Side Management solutions, Demand Response does not.

**************  

See *** below  Additional application devices supported.

Applications available with our Motor controller DERs include a variety of industrial and factory applications as well as escalators and single motor elevators.

Applications as oil field pump jacks, escalators, lifts, pumps, conveyor belts, pulverizors, metal machining and manufacture, wood working, metal presses, plastic injection molding, and more, will also see reduced electricity usage. Our Intelligent Motor Controllers also provide soft-start and soft-stop capabilities so that your motor/application devices work far more effectively while also reducing wear and tear on the motors and pulleys used, thus reducing maintenance and operating costs. Units are available in three-phase up to 1400 HP.

Thanks for the phone call offer, but I don't drive PLMA's research initiatives, our members do.  Here's hoping your company will join PLMA so you can become part of the discussion about strategic directon of research and other other initatives to help broaden our members' perspectives... and your own.

Like every technology, motor control has a place in the portfolio for demand management. It, however, is not the only solution worth considering. To manage risks, utility companies need to invest in multiple technologies that address multiple issues - and quite frankly provide new value - on the grid. I think the post title was engineered to get people's attention - which it did.  I just happen to disagree that this is the "one size fits all" solution to a complex problem.

Hi Jenny: Thank you for your comment.

We do not represent this a "one size fits all" solution to a complex problem.

Our article provides an introduction to proven technologies that can provide KW reductions as needed and reduce Demand Response Costs.

Your said: Like every technology, motor control has a place in the portfolio for demand management. It, however, is not the only solution worth considering.

Are the solutions and opportunities that we presentrd being Considered?

If not, Why No?

Your responses to the comments don't appear very open to different opinions regarding the future of DR unless they mesh with your opinions.  Good luck with that approach.
