Why Tiered Electricity Pricing Is Tricky for Non-Solar Customers

You see an electricity plan advertised at 8.5¢ per kWh. Sounds great, right? You sign up, use electricity like you normally do, and then your first bill arrives - and it's higher than what you were paying before.

Welcome to the world of tiered pricing. It's one of the trickiest parts of shopping for electricity in Texas, and it catches non-solar customers off guard more than almost anything else.

What Is Tiered Pricing?

In Texas, every electricity plan comes with an Electricity Facts Label (EFL). The EFL is required by the Public Utility Commission of Texas (PUCT) and shows you the average price per kWh at three usage levels:

• 500 kWh (low usage)
• 1,000 kWh (average usage)
• 2,000 kWh (high usage)

That advertised rate of 8.5¢? That's usually the price at 1,000 kWh only. Your actual rate at 500 kWh or 2,000 kWh could be very different.

The Bill Credit Trap

Here's why. Many plans include bill credits - a fixed dollar amount subtracted from your bill when you use more than a certain threshold. A common structure looks like this:

| Component | Amount | |---|---| | Energy charge | 11.5¢/kWh | | TDU delivery | ~4.2¢/kWh | | Bill credit (at 1,000+ kWh) | −$50.00 |

At exactly 1,000 kWh, that $50 credit makes the math look beautiful:

> (11.5¢ × 1,000) + (4.2¢ × 1,000) − $50 = $107 → 10.7¢/kWh

But at 999 kWh? You lose the entire $50 credit:

> (11.5¢ × 999) + (4.2¢ × 999) = $156.84 → 15.7¢/kWh

One kWh difference. Five cents per kWh swing. That's a $50 cliff hiding in the fine print.

The "Sweet Spot" Problem

This means tiered plans have a sweet spot - a usage range where the math works in your favor. Outside that range, you could be overpaying significantly.

Here's what a typical tiered plan actually looks like across different usage levels:

| Monthly Usage | Effective Rate | |---|---| | 500 kWh | 15.7¢/kWh | | 750 kWh | 12.3¢/kWh | | 999 kWh | 15.7¢/kWh | | 1,000 kWh | 10.7¢/kWh | | 1,200 kWh | 11.2¢/kWh | | 2,000 kWh | 12.1¢/kWh |

Notice the pattern? The rate jumps around depending on where you fall. A customer using 750 kWh per month would see a completely different effective rate than someone using 1,100 kWh - even though they signed up for the same plan.

Why This Matters for You

If you're a non-solar customer in Texas, your usage changes every month. You might use 800 kWh in April and 2,200 kWh in August. A plan that saves you money in spring could cost you more in summer.

Most comparison sites - including the official PowerToChoose.org - show you the rate at 1,000 kWh. That's helpful as a starting point, but it doesn't tell you what you'll actually pay across a full year of real usage.

How to Protect Yourself

1. Look at all three EFL price points, not just one. If the rate at 500 kWh is dramatically higher than at 1,000 kWh, there's probably a bill credit creating an artificial sweet spot. 2. Know your actual monthly usage pattern. Download your usage data from Smart Meter Texas - it shows your real consumption for every month. If your usage swings between 600 and 1,800 kWh seasonally, you need a plan that works across that entire range. 3. Calculate your cost at YOUR usage, not the advertised usage. The only way to know what a plan truly costs you is to run your actual monthly numbers through each plan's rate structure - not just multiply your usage by the advertised rate. 4. Consider flat-rate plans. Plans with no bill credits and a simple per-kWh rate are more predictable. You won't get the flashy low number at 1,000 kWh, but you also won't hit any cliffs. What you see is what you get.

The Bottom Line

Tiered pricing isn't inherently bad - some customers genuinely save money on these plans. But the savings only happen if your usage consistently lands in the right range. For everyone else, it's a pricing structure that looks cheap but costs more.

When WattTrim runs your electricity audit, we calculate your cost on every available plan using your actual month-by-month usage - not just the advertised rate. We interpolate between the EFL anchor points to find your true cost at every usage level, including the months where you'd fall outside the sweet spot.

That's the difference between picking a plan based on a single number and picking one based on 12 months of reality.
