Sacramento homeowners paid an average of $145 per month on their SMUD bill in 2025 — and with the approved 3% rate increases hitting in 2026 and 2027, that number is climbing. If you’ve been watching your summer bills spike during those brutal 100°F+ stretches in Natomas, East Sacramento, or Elk Grove, you’re not alone. The good news? Strategic electrical upgrades can cut your SMUD bill by 20–40%, and many qualify for SMUD rebates that offset the upfront cost. At TNT Electric, we’ve helped hundreds of Sacramento homeowners reduce their electric bills with targeted upgrades — not generic tips you’d find on any website, but real electrical work that delivers measurable savings month after month. Here are the 10 upgrades that deliver the biggest return on your SMUD investment.

1. LED Lighting Conversion — Save Up to 75% on Lighting Costs
Lighting accounts for roughly 15% of the average Sacramento home’s electric bill, and if your house still has incandescent or even CFL bulbs, you’re burning money every time you flip a switch. LED bulbs use at least 75% less energy and last up to 25 times longer than traditional incandescent bulbs — that’s not marketing hype, it’s physics.
For a typical Sacramento home with 30–40 light fixtures, a full LED conversion can save $200–$400 per year on your SMUD bill. The upgrade goes beyond just swapping bulbs. Older homes in Land Park, Curtis Park, and midtown Sacramento often have outdated dimmer switches that buzz or flicker with LEDs, requiring compatible dimmer replacements. Recessed can lights with incandescent trim kits should be replaced with integrated LED recessed lighting for maximum efficiency.
Cost: $500–$2,000 for a whole-home conversion including dimmer upgrades and recessed light retrofits. SMUD’s Energy Store offers $3 instant rebates per LED bulb, so stock up there first.
Pro tip: Focus on the lights you use most — kitchen, living room, and outdoor security lights deliver the fastest payback. A single 60W-equivalent LED running 5 hours daily saves about $10/year compared to its incandescent counterpart at SMUD’s current rates.
2. Smart Thermostat + Proper Wiring
Your HVAC system is the single biggest energy consumer in your Sacramento home, easily accounting for 40–50% of your summer SMUD bill when temperatures hit triple digits. A smart thermostat can reduce heating and cooling costs by 10–15% — but only if it’s wired correctly.
Here’s what most homeowners don’t realize: many Sacramento homes built before 2000 lack a C-wire (common wire) at the thermostat location. Without it, smart thermostats like the Ecobee or Google Nest draw power erratically, causing Wi-Fi disconnects and ghost cycling that can actually increase your bill. We run into this constantly in Arden-Arcade, Carmichael, and older Roseville neighborhoods.
A proper smart thermostat installation includes verifying your HVAC system compatibility, running a dedicated C-wire if needed, and programming the thermostat to align with SMUD’s Time-of-Day rate schedule. That means pre-cooling your home before the 5 p.m. peak window and letting the thermostat coast during the $0.3765/kWh summer peak hours.
Cost: $150–$400 installed, including C-wire run if needed. SMUD offers a $50 instant rebate on qualifying smart thermostats through the SMUD Energy Store — plus additional incentives if you enroll in the My Energy Optimizer® program, which rewards you for shifting energy use out of peak hours.
Pro tip: Set your smart thermostat to pre-cool to 72°F by 4:30 p.m., then let it drift up to 78°F during the 5–8 p.m. peak. You’ll barely notice the difference, but your SMUD bill will.
3. Whole-House Fan Dedicated Circuit
Sacramento’s climate is uniquely suited for whole-house fans. While our summer days are scorching, nighttime temperatures regularly drop into the low 60s — that’s a 30–40°F temperature swing you can exploit. A whole-house fan pulls cool evening air through your home and pushes hot attic air out, cooling your house for pennies compared to running the AC.
A quality whole-house fan (like the QuietCool QC ES-7000 or CL-3100) uses just 100–600 watts compared to your central AC’s 3,000–5,000 watts. Sacramento homeowners on Reddit regularly report 20% reductions in summer SMUD bills after installing one. Run it from 8 p.m. to 6 a.m. during off-peak hours ($0.1550/kWh in summer), and you’re cooling your home for roughly $0.10–$0.30 per night instead of $3–$5 with AC.
The electrical work matters here. A whole-house fan needs a dedicated 15- or 20-amp circuit from your panel — not a shared circuit that trips when the fan kicks on. We also install the proper attic venting (minimum 1 sq. ft. of net free area per 750 CFM) required by code to prevent back-pressure issues.
Cost: $1,200–$2,500 installed with dedicated circuit and proper attic venting. This upgrade often pays for itself in one to two Sacramento summers.
Pro tip: Pair a whole-house fan with a smart thermostat schedule. Set the AC to shut off at 8 p.m. and the whole-house fan to kick on via a smart switch — your SMUD bill during July and August will thank you.
4. Time-of-Use Rate Optimization with a Smart Electrical Panel
SMUD’s Time-of-Day rate structure creates massive price swings that savvy Sacramento homeowners can exploit. Under the standard 2026 residential TOD rate, summer electricity costs $0.3765/kWh during peak hours (5–8 p.m. weekdays) but only $0.1550/kWh during off-peak hours. That’s a 143% price difference for the exact same electricity.
A smart electrical panel — like the Span Smart Panel or Lumin Smart Panel — gives you circuit-level control and monitoring so you can see exactly where your energy goes and automate load shifting. It can automatically delay your electric dryer, water heater, or pool pump until off-peak hours, and prioritize essential circuits during peak pricing windows.
This upgrade requires a full electrical panel upgrade if your current panel is a 100-amp or outdated model (we still see Federal Pacific and Zinsco panels in Citrus Heights and Fair Oaks homes — those need replacing regardless for safety). A smart panel upgrade kills two birds with one stone: you get modern safety and SMUD bill optimization in a single project.
Cost: $4,000–$8,000 for a smart panel upgrade (varies by panel size and existing wiring). The ROI depends on your usage patterns, but homeowners shifting 30–40% of their consumption to off-peak hours typically save $40–$80/month during summer.
Pro tip: Even without a smart panel, you can manually shift high-draw activities. Run your dishwasher, laundry, and EV charger after 8 p.m. That alone can save $20–$30/month in summer.
5. EV Charger Scheduled Charging at Off-Peak SMUD Rates
If you’re charging your electric vehicle at 6 p.m. on a summer weekday, you’re paying $0.3765/kWh — the most expensive rate SMUD offers. Charge that same car after midnight, and you’re paying just $0.1550/kWh, minus an additional 1.5¢/kWh EV discount that SMUD offers registered EV owners for usage between midnight and 6 a.m. That brings your effective rate down to roughly $0.14/kWh — less than half the mid-peak price.
For a typical EV that uses 30 kWh per charge, that’s the difference between $11.30 per charge during peak and $4.20 per charge overnight. Over a year of daily commuting, that adds up to $2,500+ in savings just by changing when you charge.
The electrical upgrade you need: a properly installed Level 2 (240V) EV charger on a dedicated 40- or 50-amp circuit with a charger that supports scheduled charging (ChargePoint Home Flex, Emporia, or Tesla Wall Connector all have built-in scheduling). We install the circuit, mount the charger, and program the schedule so your car starts charging at midnight automatically.
Cost: $1,200–$2,500 for Level 2 charger installation including dedicated circuit. SMUD’s Charge@Home program offers up to $600 in rebates toward charger equipment and circuit installation. Don’t forget to register your EV with SMUD to unlock the overnight rate discount.
Pro tip: If your panel doesn’t have room for a 50-amp EV circuit, ask us about circuit-sharing devices that let you add EV charging without a full panel upgrade.
6. Solar Panel Prep + Net Metering Optimization
Going solar in Sacramento is a strong financial move, but the electrical prep work makes or breaks your ROI. Before a single panel hits your roof, your home’s electrical system needs to be ready — and most solar installers won’t tell you what’s lurking behind your panel cover.
Sacramento homes built before 1990 almost always need a panel upgrade to 200 amps before solar installation. If your home has a 100- or 125-amp panel (common in Tahoe Park, South Land Park, and North Sacramento), you simply can’t accommodate a solar inverter alongside your existing loads without upgrading first. Getting this done before your solar install avoids delays and double-permitting costs.
Here’s the financial picture under SMUD’s current Solar and Storage Rate: surplus energy exported to the grid earns you $0.096/kWh as of June 2026 — recently boosted from the previous $0.074/kWh rate. While that’s better than before, it’s still significantly less than the $0.3765/kWh you pay during summer peak hours. The optimization strategy is clear: use your solar power during peak hours rather than exporting it, and shift grid consumption to off-peak periods.
Electrical prep for solar includes upgrading your main panel, installing a solar-ready meter base, running conduit for the inverter connection, and potentially adding a sub-panel for future battery storage.
Cost: $2,000–$5,000 for electrical solar prep (panel upgrade + meter base + conduit), separate from the solar system itself. The federal Investment Tax Credit (ITC) covers 30% of the total solar installation cost including electrical upgrades done as part of the project.
Pro tip: Plan your panel upgrade to include space for a future battery system, even if you’re not installing one today. Adding a battery-ready sub-panel now costs $300–$500 extra but saves $1,000+ later.
7. Pool Pump Timer Circuit Upgrade
Sacramento is a pool town — roughly 25% of homes in Folsom, Granite Bay, and Roseville have in-ground pools. And that pool pump? It’s one of the biggest silent energy hogs in your home, drawing 1,500–2,500 watts and running 8–12 hours daily. On SMUD’s summer rates, running a pool pump during peak hours can add $80–$120/month to your bill.
The fix is straightforward: install a programmable timer or smart controller on a dedicated pool pump circuit that runs the pump exclusively during off-peak hours. At $0.1550/kWh off-peak versus $0.3765/kWh peak, you’re cutting pool pump energy costs by nearly 60% just by shifting the run time.
Better yet, if your pump is more than 8 years old, upgrading to a variable-speed pool pump (required by California Title 20 for new installations) reduces energy consumption by 60–80% on its own. A variable-speed pump on a dedicated circuit with off-peak scheduling is the ultimate combo. The electrical work involves running a new dedicated 240V circuit to your pump equipment pad and installing a weatherproof timer or smart relay.
Cost: $400–$800 for a timer/smart controller installation on an existing circuit; $1,200–$2,000 if a new dedicated circuit run is needed. Variable-speed pump + electrical: $2,500–$4,000 total.
Pro tip: Schedule your pool pump to run from midnight to 8 a.m. The filtration works just as well at night, and you’ll avoid every penny of peak and mid-peak SMUD pricing.
8. Insulation + Electrical Weatherization Combo
This is the unsexy upgrade that delivers some of the biggest SMUD bill reductions. Sacramento’s extreme temperature swings — from 38°F winter mornings to 105°F summer afternoons — mean your home’s thermal envelope is constantly fighting to maintain comfort. When that envelope leaks, your HVAC works overtime and your SMUD bill explodes.
The electrical side of weatherization includes sealing air leaks around electrical outlets, switches, and recessed light fixtures on exterior walls and ceilings. Every unsealed outlet box on an exterior wall acts like a small open window. In older Sacramento homes — especially those in Midtown, Oak Park, and the Fab 40s — we routinely find recessed lights with no IC (insulation contact) rating, creating mandatory gaps in attic insulation that pour heat into your living space.
Our approach bundles energy-efficient electrical upgrades with insulation work: we replace non-IC-rated recessed cans with airtight IC-rated LED fixtures, install foam gaskets behind every outlet and switch plate on exterior walls, and seal wire penetrations in your attic and crawlspace. Combined with proper attic insulation (R-38 minimum per California Title 24), these upgrades can reduce HVAC energy consumption by 15–25%.
Cost: $800–$2,000 for the electrical weatherization component (recessed light replacements, outlet sealing, wire penetration sealing). Full attic insulation + electrical weatherization packages run $2,500–$5,000. SMUD’s Home Performance Program (HPP) bundles energy-efficiency upgrades and may offer additional rebates when you combine multiple improvements.
Pro tip: Start with an energy audit. SMUD offers free home energy assessments that identify your biggest loss points. We then target the electrical fixes that deliver the fastest payback.
9. ENERGY STAR Appliance Circuit Upgrades
Upgrading to ENERGY STAR appliances is one of the most effective ways to reduce your SMUD bill — but many Sacramento homeowners hit a wall when their home’s wiring can’t support modern, efficient equipment. That vintage 1970s Carmichael kitchen with two-prong outlets and shared circuits wasn’t designed for today’s high-efficiency appliances.
Common electrical upgrades needed for modern ENERGY STAR appliances include:
- Dedicated 20-amp kitchen circuits — NEC code requires at least two dedicated 20-amp small appliance circuits for countertop receptacles, but older homes often have just one shared circuit
- 240V circuit for induction cooktop — Switching from gas to induction (SMUD offers $750 rebates for gas-to-electric conversions) requires a dedicated 40- or 50-amp circuit
- Heat pump water heater circuit — These ultra-efficient units (qualifying for up to $4,000 in SMUD rebates) need a dedicated 30-amp, 240V circuit, and they perform best in garages where Sacramento’s warm climate helps the heat pump operate efficiently
- Updated grounding and GFCI/AFCI protection — Required by current NEC code for new circuit installations
The cumulative savings add up fast. An ENERGY STAR refrigerator uses 15% less energy than non-certified models. A heat pump water heater uses 65% less electricity than a standard electric tank. An induction cooktop is 85–90% energy efficient compared to 70% for a standard electric range.
Cost: $300–$800 per dedicated circuit; full kitchen circuit upgrade packages run $1,500–$3,500. SMUD appliance rebates ($50–$4,000 depending on the appliance) offset a significant chunk.
Pro tip: Bundle multiple circuit upgrades into a single project. Running three new circuits in one visit is far more cost-effective than three separate service calls — and we can coordinate with your appliance delivery schedule.
10. Battery Storage Integration for Peak Shaving
Battery storage is the most advanced — and increasingly the most financially compelling — way to lower your SMUD bill in Sacramento. The concept is simple: charge your battery during cheap off-peak hours ($0.1550/kWh) and discharge it during expensive peak hours ($0.3765/kWh). That price arbitrage saves you money on every kilowatt-hour you shift.
A typical home battery system like the Tesla Powerwall 3 (13.5 kWh) or Enphase IQ Battery 5P can store enough energy to power your home through the entire 5–8 p.m. peak window and into mid-peak evening hours. At SMUD’s current summer rate differential, peak shaving with a single battery can save $50–$100/month during summer — more if paired with solar.
The real incentive game-changer is SMUD’s My Energy Optimizer Partner+ program, which offers a one-time enrollment incentive of up to $10,000 for new battery storage customers, plus ongoing quarterly payments for participating in virtual power plant events. Combined with the federal 30% tax credit on battery installations (when paired with solar or as a standalone starting in 2023 under the Inflation Reduction Act), the effective cost of a battery system drops dramatically.
The electrical work for battery integration includes installing a dedicated battery sub-panel, a transfer switch or gateway for backup capability, and proper interconnection with your existing panel and SMUD’s grid. If you’re pairing with solar, the battery and solar systems need to be designed together for optimal performance.
Cost: $12,000–$18,000 installed for a single battery system before incentives. After the federal tax credit and SMUD incentives, net cost can drop to $3,000–$8,000. Payback period: 5–8 years depending on usage and solar pairing.
Pro tip: Even if you have solar, a battery makes the math work better under SMUD’s Solar and Storage Rate. Instead of exporting surplus solar at $0.096/kWh, store it and use it during peak hours when it’s worth $0.3765/kWh to you. That’s nearly 4x the value per kWh.
Frequently Asked Questions
How much can I realistically save on my SMUD bill with electrical upgrades?
Most Sacramento homeowners save 20–40% on their SMUD bill by combining two or three of the upgrades listed above. The biggest immediate impacts come from LED conversion ($200–$400/year), smart thermostat optimization ($150–$300/year), and shifting high-draw appliances to off-peak hours ($300–$600/year). Battery storage and solar provide the largest long-term savings but require a bigger upfront investment.
What is SMUD’s Time-of-Day rate and how does it affect my bill?
SMUD’s Time-of-Day (5–8 p.m.) Rate charges different prices depending on when you use electricity. In summer 2026, you pay $0.3765/kWh during peak hours (5–8 p.m. weekdays), $0.2139/kWh during mid-peak (noon–5 p.m. and 8 p.m.–midnight), and $0.1550/kWh during off-peak (midnight–noon). Weekends and holidays are always off-peak. Shifting energy use away from that 5–8 p.m. window is the single most impactful thing you can do to lower your SMUD bill.
Do I need a permit for electrical upgrades to save energy in Sacramento?
Yes, most electrical work in Sacramento County requires a permit. Panel upgrades, new circuit installations, EV charger wiring, and solar/battery interconnections all require permits and inspections to meet NEC and California Title 24 code requirements. At TNT Electric, we pull all necessary permits and schedule inspections as part of every job — you never have to visit the building department yourself.
