The Issue - Growing Plug Load“Plug loads for household electronics account for 15-19% of residential energy use and are increasing as more households purchase more electronics” - California Energy Commission PIER

“Energy Star labeling of electronic products with lower standby power levels. But public policies and programs have paid insufficient attention to active-mode energy use becauseof a lack of detailed information about the quantity and types of devices and use patterns in the home.” - California Energy Commission PIER

Low Income, High TV Penetration

• Larger TVs that consume more energy are less expensive• Creating demand with unique features encourages early

upgrade/replacement (Smart TV, 3D TV, thinner designs, LED, Ultra HD, etc.)

• Ultra HD TV’s are 30% more energy intensive than Standard HD• TV manufacturers are not alone, new PS4, Xbox One, Wii U, smart

BluRay players, media streamers, etc.• This is creating “The Refrigerator Syndrome” where the existing units

will get handed down, added to additional rooms, creating more overall plug load

• Adding more TVs and devices to more rooms means more peripherals shuffled around further increasing household plug load

Increasing Plug LoadAs the CFL savings values drop and becoming harder to capture and LED in its infancy, plug load is another cost effective efficiency area to help reach demanding kWh reduction targets.

Targeted Areas

Consumer electronics waste power in two distinct ways: – Passive standby where power is

used by the product to keep it ready to switch on (vampire/phantom)

– Active Power Wastage where the product is on but not performing its main function (e.g. TV is on but is not being watched)

An ideal efficiency approach would target both types of waste.

Active power wastage

As the Net to Gross value for CFLs continues to drop and LED is too becoming challenging, addressing plug load is the next cost effective efficiency area to help reach kWh reduction targets.

Overview - Tier 1 APS• First Generation Advanced Power Strips (APS) are a master

control device that reduce standby power• Benefits of Tier 1 APS

• Inexpensive• Save only 26 kWh annually if installed and used correctly• Good for proactive energy savers who don’t mind

inconvenience

• Issues with Tier 1 APS• Only saves 4% of overall AV energy usage• Only saves energy if someone takes action• Not intuitive, many must be manually adjusted

by the user• AV equipment usage now inconvenient• High de-installation rate• There are additional well known issues also

Embertec Addressing Plug Load• Have been working with the CA IOU’s for last 4 years to

evaluate Tier 2 Advanced Power Strips (APS)

• Participated in the idea 365 program to introduce Tier 2 APS to CA market

• CEC funded CalPlug has undertaken an assessment on Tier 2 APS technologies

• Millions of Tier 2 APS have been deployed already – however not yet in CA.

• Bonneville Power Authority has approved Tier 2 APS based on trials conducted under the direction of CA IOU’s in CA homes..

• Canadian Utilities also installing Tier 2 APS in their energy efficiency programs based on CA field trial data

Overview – Tier 2 APS2nd Generation Advanced Power Strips utilize advanced controls-micro processor with greater automationBenefits:• Address both Active and Passive Standby waste• Automated savings/Automatic adjustment• Saves up to 48-53% of total AV area energy usage• Real world CA field trials:

• CalPlug Assessed 346 kWh , 300 kWh BPA Deemed

• Real world proven savings (millions installed to date)• Low cost per kWh saved - $0.20/kWh for Tier 2 compared with

$1.15/kWh for Tier 1 APS.• Tier 2 APS 6 times more cost effective and over 11 times the energy savings

over Tier 1 APS.

• No workaround to operate AV equipment required• Proven high retention rate

SDG&E Field Trial

10

• Residential and Commercial Tier 2 APS field trial recently completed

• All CA IOU’s are aware of and awaiting the final work-paper both from SDG&E and the CalTF

• Preliminary findings are directly in-line with CalPlug work-paper.

• 50% energy reduction in AV environments

• Around 300kWh annual savings in Residential and Commercial environments

Low Income Applicability

11

• Easier to use than Tier 1 APS

• Current ESA Program Performance:

– 350 Annual kWh savings with Tier 1 APS

– $1,170 per home (including thermo savings)

• Inclusion of Tier 2 APS in ESA program will deliver:

– 625 Annual kWh savings with Tier 2 APS

– $1,198 per home (including thermo savings)

• An additional 2.3% expenditure per Low Income home will almost double the current ESA program kWh savings.

• On average two Tier 2 APS devices per home are applicable:

– $1258 per home will deliver – 925 kWh savings annually

– To put simply the ESA program could move from $3.34/kWh saved to $1.36/kWh saved.

Low Income Inclusion Challenges

12

• Even with previously reported (CalPlug) metrics some IOU’s are claiming Tier 2 APS is less cost effective than Tier 1 APS…

• Discussion with the CPUC and an assessment using the E3 calculators of all 3 IOU’s has demonstrated that Tier 2 APS are clearly a much more cost effective measure than Tier 1 APS

• The longer it takes to migrate to more efficient APS technology, the greater the ongoing disadvantage to Low Income residents who are losing kWh reduction opportunities through the adoption of Tier 1 APS.

Further Value from Tier 2 APS

13

• Tier 2 APS can today also be offered with cost effective communications capabilities which will provide:– Smartphone interface presenting greater value

proposition to householders– Ability to verify Tier 2 APS installation automatically– Ability to verify Tier 2 APS retention rates automatically– Interface with the IOU to communicate grid constraints or

time of use tariff information to the householder– A platform towards additional energy efficiency and

control capabilities that will assist in addressing the energy/water nexus

Proposed Next Steps

14

• Present the final findings from the SDG&E Field Trial for residential Tier 2 APS application

• Further discussion with representatives of the LIOB to discuss the steps towards inclusion of Tier 2 APS within the ESA program

• To provide a detailed overview (by IOU) on the stated barriers preventing the inclusion of Tier 2 APS

Tier 2 APS is an activity which is currently being deployed in other parts of North America with millions deployed in overseas energy efficiency programs since 2011.
