Last Year's "Summer Happy Hour" Saw 110,000 Participants; Octopus Energy Announces Its Return This Summer with Electricity Bill Support

Octopus Energy, which ranked first in growth rate among the top 30 electricity companies in 2024, has decided to implement its customer service program "Summer Happy Hour 2026" from Thursday, July 16, to Wednesday, September 16, 2026.

The Summer Happy Hour is a customer service program that provides benefits based on electricity usage during the "Happy Hour" from 11 AM to 1 PM every day. It supports a lifestyle that is kind to household budgets and allows for comfortable electricity use, while also utilizing daytime hours when solar power generation peaks.

The top 30 companies refer to the top 30 companies by total electricity demand for low-voltage lighting in 2025. The growth rate is calculated by dividing the total electricity demand for low-voltage lighting in 2025 by the total electricity demand for low-voltage lighting in 2024 and subtracting 1. For Octopus Energy, the growth rate compared to 2024 is 63%.

Approximately 110,000 customers participated in the "Summer Happy Hour" held for the first time last year. The average benefit per customer was approximately 335 yen, recording a還元 level about 10 times higher than the summer energy-saving measures of the previous year. As a flagship summer initiative for Octopus Energy, it was well-received by many customers.

Amidst the prolonged high prices and increasing severity of summer heat, Octopus Energy will once again support customers in having a summer where they can use electricity with peace of mind.

From "Saving Electricity" to a Summer of "Using with Peace of Mind"

In recent years, summer heat has become increasingly severe year by year, and intense heat is expected again this year. In addition, many consumers are concerned about their household finances due to prolonged high prices and uncertainty surrounding energy prices.

Especially in the summer, many people hesitate to use air conditioning due to concerns about electricity bills. However, in recent years, the prolonged heatwaves have increased the risk of health problems such as heatstroke from excessive saving measures.

In this context, Octopus Energy launched the "Summer Happy Hour" last year. The Summer Happy Hour aims to achieve both a comfortable lifestyle and reduced household burden by refreshing the concept of "saving = cutting electricity (enduring)" and adopting an approach of "smart usage" that leverages time slots rich in solar power generation.

Towards a Summer Where Customers Can Use Electricity with Peace of Mind Again This Year

Since its founding, Octopus Energy has advocated "Greener electricity, more affordable," based on the belief that "green choices should not come at the expense of household finances or comfort."

This summer, we will implement the Summer Happy Hour, which applies a "discount based on usage" so that customers can use electricity with peace of mind when they need it, by utilizing green time slots.

This is not just a simple discount program, but will be developed as a unique Octopus initiative to support both customers' comfortable living and the reduction of household financial burdens.
