History of Keravan Energia
It all began with electric light and the steam engine.
In 1906, miracles were experienced in Kerava
Electric lights were illuminated for the first time in the parlor of the Yli-Heikkilä farmhouse, powered by a steam engine located at old man Löfberg’s mill and sawmill. This marked the beginning of a multi-stage development process, during which Kerava’s energy operations were advanced – initially within the framework of the Greater Tuusula region, and later through the town’s own dedicated electric utility. In 1992, the operations were incorporated, and a few years later, a subsidiary named Etelä-Suomen Energia Oy (now Sipoon Energia Oy) was established for Keravan Energia Oy. The Keravan Energia Group had come into being.
Until 1955, the construction of the electricity network and the distribution of electricity were part of the operations of Keravan Puuteollisuus Oy. As operations expanded, the network and distribution rights were sold to the Tuusula Region Electricity Utility; subsequently, in 1964, the Kerava Market Town Electricity Utility separated from this entity to become an independent operator.
At the turn of the decade into the 1970s, the market town of Kerava became a city. This transition brought about new developments: Kerava acquired its own thermal power plant, and the construction of a district heating network began.
In 1982, it was decided to rename the electricity utility Keravan energialaiton, Kerava Energy Utility, as its services were no longer limited solely to electricity. The utility operated under this name for ten years.
The year 2006 marked one hundred years since the first home in Kerava was electrified. Today, electrical energy flows to the city’s homes and businesses primarily via underground cables. In addition, thermal energy is distributed underground to almost every part of the city. The company also operates a district heating network in Sipoo; the municipality joined Kerava Energia as a municipal owner in 1994, coinciding with the launch of district heating operations there.
Roots of Sipoon Energia
The electric power company Etelä-Suomen Voima Oy (ESV) was established in 1916 to generate and supply electricity—initially to municipalities and large-scale consumers in Helsinki and the areas to its east. During its early years, ESV constructed, among other infrastructure, the Porvoo–Helsinki power transmission line. The company significantly expanded its operational area by acquiring local electric utilities, and in 1946, it also began distributing electricity to smaller-scale customers.
Following corporate restructuring in 1990, ESV’s distribution operations were transferred to a new subsidiary, Etelä-Suomen Sähkö Oy. Five years later, Etelä-Suomen Energia Oy—a new subsidiary of Kerava Energia Oy—acquired the network and distribution operations in the Sipoo area. The staff who had previously managed electricity-related matters in the Sipoo region transferred to the employ of Etelä-Suomen Energia, retaining their status as existing employees. In 2018, Etelä-Suomen Energia was renamed Sipoon Energia.
15 year of district heat in Karkkila
Keravan Energia expanded its district heating operations to Karkkila in 2000. The local district heating networks were actively developed for 15 years, until 2015, when Keravan Energia sold its Karkkila district heating business to Vapo. The reason for the sale was that Keravan Energia wished to focus its resources on developing its other district heating areas.
A new look and new tricks
In 2015, Keravan Energia revamped its corporate identity, as the company’s logo and colors had become outdated and no longer accurately represented the rapidly evolving energy company. The identity created at that time was updated in 2026.
Throughout 2015 and 2016, the company’s presence was visible across the town in various ways: a large-scale solar power plant was built in Kerava, new electric vehicle charging points were installed, electrical cabinets were decorated with historical photographs, and transformer stations were painted by students from the Kerava School of Visual Arts. Additionally, charging lockers for mobile devices—where phones could be charged free of charge—were provided to libraries and youth centers in Kerava and Sipoo.
Responsibility as a guiding principle in the 2020s
The purpose of the Keravan Energia companies is to foster well-being in our region. Responsibility is therefore reflected in everything we do—from affordable electricity transmission to supporting local cultural and sports activities.
We also work continuously and purposefully to promote sustainable development. In our energy production, we invest in domestic renewable energy sources.
