What Is Energy Arbitrage?

Energy arbitrage is a simple concept with a big impact:

Use electricity when it’s cheap. Avoid it when it’s expensive.

For homeowners in Oregon, this doesn’t mean selling power back for profit — it means strategically reducing your utility bill by controlling when your home pulls electricity from the grid.

With a properly designed solar + battery system, you can shift your energy usage and avoid the most expensive rates of the day.

How Time-of-Use (TOU) Pricing Works in Oregon

Utilities like Portland General Electric (PGE) and Pacific Power are moving toward Time-of-Use (TOU) rate structures.

Typical TOU structure:

• Off-peak (lowest cost): Midday and overnight
• Mid-peak: Shoulder hours
• Peak (highest cost): ~4pm–9pm

The problem:

👉 This peak window is when most households use the most energy — HVAC, cooking, lighting, EV charging.

That means you’re paying the highest rates at the worst possible time.

How Solar + Battery Storage Creates Energy Arbitrage

A solar-only system helps.
A solar + battery system gives you control.

Here’s how it works:

1. Produce energy during the day
Your solar system generates power when the sun is out — often more than your home needs.

2. Store excess energy
Instead of sending all that energy back to the grid, your battery stores it.

3. Use stored energy during peak hours
When electricity rates spike in the evening, your system automatically pulls from your battery instead of the grid.

The result:

• Lower utility bills
• Reduced exposure to peak pricing
• Smarter energy usage

PGE and Pacific Power Rate Increases (2020–2025)

Utility rates in Oregon have been steadily rising — and that trend is expected to continue.

Portland General Electric (PGE)

• Multiple rate increases from 2020–2025
• Estimated cumulative increase: ~30%–40%+
• Key drivers:
  • Grid upgrades and reliability improvements
  • Wildfire mitigation investments
  • Transition to renewable energy
  • Inflation and operating costs

Pacific Power

• Consistent annual rate adjustments
• Estimated cumulative increase: ~25%–35%+
• Key drivers:
  • Infrastructure modernization
  • Rising energy procurement costs
  • Environmental and regulatory compliance

👉 Bottom line: Electricity is getting more expensive — and faster during peak hours.

Why Energy Arbitrage Matters More Than Ever

Historically, solar savings relied heavily on net metering (1:1 credit in Oregon).

But the market is shifting:

• Utilities are evaluating changes to net metering
• TOU pricing is expanding
• Peak rates are rising faster than average rates

The new reality:

The value of solar is no longer just what you send to the grid — it’s how you use your own energy.

Benefits of Solar Energy Arbitrage for Oregon Homeowners

With solar + battery storage, you can:

• Avoid peak electricity rates
• Lower your monthly utility bill
• Protect against future rate increases
• Keep your home powered during outages
• Increase long-term ROI of your system

This is especially important in Oregon, where:

• Winter storms can cause outages
• Energy demand is rising
• Utility costs continue trending upward

Is Solar + Battery Right for Your Home?

Energy arbitrage works best for homeowners who:

• Use most of their electricity in the evening
• Want protection from rising utility rates
• Are considering battery backup for outages
• Plan to stay in their home long-term

Take Control of Your Energy Costs

Solar alone helps reduce your bill.
Solar + battery storage puts you in control.

As PGE and Pacific Power rates continue to rise, energy arbitrage is becoming one of the most practical ways to manage long-term energy costs in Oregon.
