Is it profitable to keep a coffee shop open during blackouts?

Blackouts brought back an old dilemma for coffee shops: work in the dark or close their doors until better times. But recent years have shown something else — those who were able to switch to autonomy not only survived but in some cases earned more than on normal days. Cafés are no longer just places to buy coffee — they have become places where you can charge your phone, warm up, and work. This has changed customer behavior and affected business profitability.

How profitability changed during power outages

On days when the power was out, the average attendance at cafes with stable operations increased by 20-60% depending on the area. Some guests were attracted by a simple factor: “there is light and Wi-Fi here.” Others were attracted by the opportunity to get a hot drink and recharge their gadgets.

For many establishments, this meant revising their operating model: a reduced menu, fewer cold desserts, and an emphasis on beverages that did not require lengthy heat treatment. However, even with this format, the average check remained stable. Revenue grew most in coffee shops in residential areas and near office clusters — that’s where people were looking for “islands of autonomy.”

How much does autonomy cost?

Complete energy independence for a coffee shop consists of three components: a generator or inverter system, batteries with sufficient capacity, and high-quality ventilation for safe operation of the equipment.
The most common configuration for a small coffee shop:

• 5–7 kW generator or inverter + batteries;
• voltage stabilizer;
• connection of coffee machines, refrigerators, lighting, and Wi-Fi.

On average, the cost of an autonomous kit starts at 35–60 thousand UAH for a basic solution and can reach 100–140 thousand UAH for a system capable of keeping the establishment running for several hours without interruption. For some cafes, sound insulation or additional ventilation equipment is added to this amount.

When will the generator pay for itself?

The payback period depends not so much on the number of hours of power outages as on the extent to which the establishment can capture traffic from competitors that are not operating. If an autonomous coffee shop remains open even during prolonged power outages, it will see an increase in revenue, which will directly reduce the payback period.

On average:

• a small coffee shop will recoup its investment in 2–5 months of active blackouts;
• establishments with high traffic — in 1–2 months;
• in residential areas, the payback period is longer but more stable — 5–7 months, because guests return regularly.

It is also important to consider indirect benefits: when a coffee shop remains open, it maintains a steady flow of customers and does not “fall out” of their route. This reduces the risk of losing your customer base and maintains loyalty during long periods of instability.

Examples of coffee shops that thrived in the dark

During last year’s power outages, many small coffee shops showed that autonomy can be a growth point. For example, a café in Lviv that installed an inverter system and a powerful battery increased its daily revenue by 40% during blackouts. In Odesa, a small coffee shop with 12 seats received a steady stream of freelancers who came to work during power outages and retained this traffic even after the situation stabilized.
There are other cases: establishments near the metro began to function as “gathering points” for neighbors — people came to charge their phones and stayed for coffee. As a result, several of them opened second locations thanks to the increase in business during the dark days.
