15-Minute Electricity Prices: What Does It Mean for You?

From 1st October 2025, the electricity market is changing. Instead of one fixed electricity price per hour, we’ll now have a new rate every 15 minutes. That’s 96 different prices a day instead of just 24.

This means more opportunities to take advantage of cheap electricity, and, if you’ve got the right setup at home, more chances to sell power at a high price.

Why Are Prices Changing?

Electricity prices are influenced by how much energy is available on the grid at any given time. Supply and demand fluctuate more frequently than once an hour, so introducing 15-minute pricing makes sense.

With these shorter pricing intervals, energy suppliers can match supply and demand more efficiently. For you as a consumer, this means you can potentially save money by using electricity when it’s cheapest.

Why Batteries and Smart Systems Offer the Best Value

If you’ve got a home battery system and smart controls in place, you can really take advantage of these price fluctuations.

You can charge the battery when electricity is cheap and either use it yourself or sell it back to the grid when prices are high. It all happens automatically—there’s no need to manually monitor prices. Smart systems do the hard work for you, managing when the battery charges or discharges.

Claus P. Blicher from AI Power explains:

If you also own an electric vehicle or a heat pump, the benefits multiply, as your electricity use is higher, and so the potential savings are greater.

Without smart equipment or automation, the savings you’ll see from 15-minute pricing are likely to be minimal.

What Do You Need to Be Ready?

To make the most of 15-minute electricity prices, two things need to be in place:

• Your electricity meter must be able to record usage every 15 minutes. Most modern smart meters already support this, but some older models may need to be updated or replaced.

• Your electricity tariff must offer quarter-hour pricing. Many providers still stick to hourly pricing, and with some, you’ll need to request the change yourself.

Batteries and Smart Controls: How It Works

A battery acts as a buffer—or even a savings account—for electricity. It stores cheap electricity that you can use later.

To really make the most of 15-minute pricing, smart control of your battery is a huge advantage. These AI-based systems automatically manage your battery for you, keeping an eye on electricity prices around the clock.

The system will charge your battery during the cheapest 15-minute intervals and discharge—or sell—during the most expensive ones. It also avoids selling electricity when prices go negative, so you don’t lose money.

It can also store power for the times you actually need it, like in the evenings.

A system like IntelliCharge.AI takes care of everything, so there’s no need for you to watch prices or tweak settings.

Claus P. Blicher comments:

Frequently Asked Questions Can I switch to 15-minute pricing straight away?

That depends on your electricity meter and your current tariff. Contact your energy supplier and ask. If they don’t offer it, you can always switch to one that does.

Do I need to be tech-savvy?

Not at all. These systems are designed to run themselves. You can monitor everything via an app, but you don’t need to do anything manually.

Is this only happening in Denmark?

No. It’s being introduced across the EU and also here in the UK. It’s part of the shared European day-ahead market (SDAC).

Checklist – How to Get Started

1. Ask your network operator if your meter supports 15-minute pricing.

2. Check your energy tariff and speak to your supplier about switching to quarter-hour pricing.

3. Use a smart control system that can manage your battery automatically—for example, IntelliCharge.AI.
