How much energy does a brewery or winery use?

A small brewery uses about 15 kWh of electricity per hectolitre of beer (BtoBeer). In one survey, English and Welsh wineries used on average 0.557 kWh of energy per litre of wine (UK Data Service). Cooling is the largest share of winery energy consumption, but the bill follows the harvest or brew-week peak that a business battery can carry.

Most of the year your site runs quietly, then the harvest, a week of brew days or the bottling line comes. The press, the pumps and the chiller run at once, and the chiller runs flat out for weeks. In Flanders one busy harvest week can raise your grid cost for twelve months.

What drives energy consumption in a winery, brewery or distillery?

Cooling, in all three. Fermentation gives off heat, and beer, wine and cider must stay at a set temperature while they ferment, mature and wait to be bottled. The rest is packaging, pumps, compressed air, and for distillers the still.

The brewery figures come from a French trade review of small breweries (BtoBeer). Its range is 8 to 30 kWh of electricity per hectolitre, plus about 45 kWh of heat, with cold production the biggest electric share.

For wineries, refrigeration "accounts for as much as 50 per cent to 70 per cent of winery electricity consumption" (Wine Australia). Heat for brewing or distilling often comes from gas or steam. If you electrify the kettle or the still, it becomes your largest single load.

Why does the harvest or a brew week set your peak for the whole year?

Because the grid bill counts your highest quarter-hours, and your busiest weeks are few and heavy. A wine estate may press, destem, pump and cool at full power for a few weeks in autumn. A brewery stacks the brew kettle, the chiller and the bottling line on the same days.

The electrician of a mobile bottling trailer says "every facility has a 3 phase hookup because that is what almost all grape processing equipment uses". The bill that follows is not about the kWh, but about the one quarter-hour when everything ran together.

In Flanders, Fluvius bills small businesses on "the highest quarter-hour power of the month", averaged over the last twelve months. The minimum is 2.5 kW (Fluvius). So a harvest peak in October stays in the average until the next October.

The Australian wine magazine Winetitles describes the same trap. A demand tariff charges "the highest peak of energy consumption, even if it only hits that peak once in the entire year".

In Flanders the vineyard area grew from 72 hectares in 2006 to 1,041 hectares in 2025 (Departement Landbouw en Visserij). APAQ-W counts about 100 breweries in Wallonia.

How to calculate your capacity tariff is explained in our article on the capacity tariff for businesses. To find that peak in your own data, read our article on peak demand in a business.

What can you change before you add solar or a battery?

Cool warmer, cool at the right time, and never start everything together. The chiller, the one load that runs all year, often runs colder and longer than the wine or beer needs. These steps cost little, and they make any battery you add later smaller.

Do solar panels cover the cooling of a winery or brewery?

In summer, largely; at harvest and at night, not. The sun is strongest when the cellar, the cold room and the fermenters need the most cooling. But the autumn harvest falls when the days get short, and fermentation does not stop at sunset.

So a large roof on a brewery or a wine shed pays best when you use the power yourself. If the chiller can pre-cool tanks or a buffer at midday, the solar goes into cold instead of to the grid.

Does solar still pay on a business roof in 2026? Our article on business solar panels answers that. Which tax deductions apply is in our article on subsidies for business batteries and solar.

Many drinks makers also need hot water, for cleaning, bottle washing or mashing. Sending surplus solar into a boiler or buffer tank can come before a battery. On a farm in Tielt, a battery system with smart control sends surplus energy into boilers.

That farm takes only 5% of its yearly power from the grid. Our article on surplus solar into hot water explains when that is the better first step.

When does a battery earn its place at a brewery, winery or distillery?

When it has three jobs: shave the busy-week peak, move midday solar to the evening chiller, and keep fermentations cool in a power cut. One of those jobs alone rarely justifies it.

• Peak shaving: the battery delivers the extra power when the press, the pumps and the chiller run together, so the grid sees a flatter line. How that works is explained in our article on peak shaving with a battery.
• Solar shifting: midday surplus charges the battery, and the battery runs the chiller in the evening and at night.
• Continuity: a warm fermentation or a warm tank of beer can be lost. A battery keeps the chiller, the pumps and the controls running when the grid fails. How long it keeps a cold room cold is covered in our article on cold rooms in a power cut.
• Cheap hours: with a dynamic contract, the battery can also charge when grid power is cheap. See our article on a dynamic energy contract with a battery.

A business battery is modular, so it can be sized on the real harvest or brew-week peak and grow with the cellar. Monitoring and control come with it, so you see what the chiller, the line and the battery do. Our article on an energy management system for a business explains what the control layer adds.

What do we need to look at your brewery, cellar or distillery?

Your meter data from a busy week, your machine list and your cooling set-up. With that we can tell you what sets your peak, what planning changes, and whether solar, a battery or both make sense.

1. Step 1: Send us a year of quarter-hour data from your digital meter, or at least the harvest, brew or bottling weeks.
2. Step 2: List the chiller (kW, set points, glycol or brine), the press, pumps, bottling line and compressor. Add an electric kettle or still if you have one.
3. Step 3: Describe your season: when you harvest or brew, when you bottle, and how long fermentations run.
4. Step 4: Where possible we measure the site over a period, so the battery and inverters are sized on real numbers.
5. Step 5: We put the options side by side: planning and set points, solar, hot water from surplus, a business battery, or a combination.
