Emerging Technology for Multifamily Water Heating

Keshmira McVeyProgram Manager – BPA

Market Opportunity

• EE savings potential of several hundred MWa

• 2018 utility all hot water savings .003 MWa

• More analysis needed from building stock assessments

4

How can we get more MFWH savings?

Is one for one replacement

suitable?

Can I daisy chain units together for greater efficiency?What if new

GWP regs come about?

Will tenants be satisfied with performance?

Can we design a plug and play

model?

What happens if it is really cold

outside?

How efficient is it?

Grid Interactive Water Heaters (aka: CTA-2045)

Tony Koch Bonneville Power

May 14, 20193:15 - 4:30p

EFX19: Coeur d’Alene, ID


14

Click to edit Master title styleThe Challenge: Demand Response Opportunity

Residential water heaters are an attractive DR resource

Traditional practice is On / Off control via external power switch

Switch installation is costly, disrupts the consumer

Requires an electrician to install the switch

Turns into a costly stranded investment if consumers opts out

It is ranked as one of the least cost effective DR resources for BPA


15

Click to edit Master title styleThe Solution: CTA-2045

A modular, open source, DR specific communications port and command language

Consumer Technology Association (CTA) published the standard in 2013 and was updated in 2018

The standard is now ANSI approved and used internationally

Two form factors: DC (3V) and AC (240V)


16

Click to edit Master title styleExamples of DC and AC forms


17

Click to edit Master title styleAdvantages of a Standard Socket = Lower Cost !

USB is analogous to CTA2045• Standard Physical Socket • Standard format for data packets• Standard initial exchange of information• Does not depend on DR language

Examples of standard sockets in the photo• 120V electrical outlet• USB (in various form factors: mini, micro, standard)

Water Heater Manufacturers and Utilities• Manufacturers can built one type, at scale

• Utilities can choose their back-haul commso AMI, cell, proprietary, and future technologies

• Open standard means lower cost at scale

• Use the same module on multiple appliances o Mitsubishi HVAC heat pumps


18

Electric Power Research Institute (EPRI) provided initial technology proving and demonstrations (2013 – 2016)

water heaters, thermostats, EV charging, pool pumps, PTACs

BPA regional CTA-2045 water heater DR project (2016 – 2018)
