PSE Flex stands out among US demand-response programs because it names line-voltage thermostats for electric baseboard heating as eligible, alongside standard central HVAC thermostats. Washington state homeowners with electric baseboard heat (common in older homes) get a rare shot at demand-response credits.

What PSE Flex Pays

PSE Flex is Puget Sound Energy’s demand-response program for residential smart thermostat customers.

Program structure:
– Enroll a qualifying smart thermostat
– PSE sends adjustment signals during peak demand events
– For heating events: setpoint may be lowered slightly
– For cooling events: setpoint may be raised slightly
– You earn bill credits for participation

Typical PSE Flex credits:
– Enrollment bonus (varies by year): $25–50
– Seasonal credits: $20–75 per season based on participation
– Event-based credits: some program structures pay per event

These figures change. Verify the current season’s amounts at pse.com before enrolling.

The Line-Voltage Thermostat Advantage

Most US demand-response programs cover central HVAC systems only, and require low-voltage (24V) thermostats that communicate through standard smart home APIs (ecobee, Nest, Honeywell).

PSE Flex explicitly includes:
– Mysa V2 (120V and 240V electric baseboard) ✓
– Sinopé (select Zigbee and Wi-Fi models) ✓
– ecobee Enhanced and Premium ✓
– Google Nest (Learning Thermostat and Nest Thermostat) ✓
– Honeywell Home T9/Sensi ✓
– Amazon Smart Thermostat ✓

For Washington state homeowners with electric baseboard heating, PSE Flex is close to the only US demand-response program offering credits for baseboard thermostat participation. Enroll Mysa or Sinopé and earn credits alongside neighbors with central HVAC: a direct financial advantage to installing a smart baseboard thermostat, beyond the energy savings.

How to Enroll in PSE Flex

Option 1: Through your thermostat app
ecobee’s eco+ automatically shows PSE Flex as an available program for PSE customers. Select it and follow the prompts to link your PSE account.

For Mysa and Sinopé (line-voltage thermostats), check PSE’s direct enrollment portal. These thermostats may not show up in app-based enrollment flows on their own.

Option 2: Through PSE’s website
pse.com → Energy Savings → Smart Thermostat / PSE Flex → Enroll. Select your thermostat model, link your PSE account, and confirm enrollment.

Option 3: Through PSE customer service
Call PSE directly if your thermostat model doesn’t appear in the online enrollment flow. Representatives can manually enroll qualifying baseboard thermostats.

Stacking with PSE’s Purchase Rebate

PSE also offers a one-time purchase rebate for ENERGY STAR certified smart thermostats (~$50–100). This is separate from PSE Flex.

Total value from both programs:
– One-time rebate: $50–100
– Enrollment bonus: $25–50
– Annual seasonal credits: $20–75/year

Over 5 years: $50–100 rebate + $125–425 in ongoing credits = $175–525 from a thermostat you’re already using.
