Who is …. ?

Wh i St ff C ti• Who is …. Steffes Corporation• Steffes Corporation is North America’s leading manufacturer of Electric Thermalleading manufacturer of Electric Thermal Storage (ETS) space and water heating systemsy

• Over the past 7 years Steffes expanded that knowhow by adding high speed communications so those systems could quickly react and respond to the needs of the Grid

Electric Thermal StoragegStorage of Renewable or Off-Peak Electricity in the form of Heat

Electricity is stored as heat in a well insulated brick core

On-board Microprocessor based control system regulates charging and discharging.

Internal blower system delivers the heat to the conditioned space as needed to maintain comfort 24/7. Storage occurs based on availability ofStorage occurs based on availability of renewable or off-peak energy or as signaled by the utility for ancillary services.

What is the …. GETS System?y

Wh t i th GETS S t ?• What is …. the GETS System?• GETS is the Steffes Corporation patented version of GIWH with real‐time control ofversion of GIWH with real‐time control of a large fleet of aggregated water heaters• Imagine 3 intersecting circles with g gGETS in the center of that shared core 

• GETS is that shared space that links DR, Energy Storage, and the “Conscious or Connected Home” ‐helping complete that entire system

GETS is cost-effective

St ff ti i t d i PJM t i l hi h• Steffes participated in a PJM trial high technology trial for “fast‐ramp resources” (batteries flywheels and our GETS system)(batteries, flywheels, and our GETS system) which later led CEO Terry Boston to say: • “Electric water heater storage is the gmost cost‐effective form of energy storage available … “ 

• “… a resource with a combined energy storage capacity on par with today’s pumped storage hydro fleet “

O’ahu Pilot Goal

Th hi l f thi GIWH Pil t• The overarching goal of this GIWH Pilot was to determine the ability of an aggregated fleet of GIWHs to provide a dispatchablefleet of GIWHs to provide a dispatchable electric grid resource that is able to respond to fast‐response signals to provide system p g p yflexibility

Concerns particular to Hawaiip

• Approved / Installed Distributed• Approved / Installed Distributed Generation (mostly rooftop PV) has grown to 69,330 across all the islandsgrown to 69,330 across all the islands• On O’ahu 16% of all residential

customers have rooftop PV – about p316 MW or 37% of the average load of 850 MW

• Most of that load is both “invisible” and uncontrolled by HECO

PV – Water Heating - Hawaii g

O’ h S l R di (kWh/ 2/d ) i• O’ahu Solar Radiance (kWh/m2/day) varies 20% high month to low month

• A 4 kW system (smaller than most) producesA 4 kW system (smaller than most) produces about 6354 kWh / year

• An typical residential household on O’ahu ypuses an average 7.28 kWh of hot water /day 

• Assuming residential electricity use at 550 / /kWh / month (6600 / yr) means that 40% of 

the typical electric load is water heating
