Cities, companies upgrading their electrical equipment to save on their electricity bills | New

Every summer, the first people are in the pool at the Kalev Spa water park in Tallinn at 8 a.m., and swimmers have actually requested that the center open even earlier as well. According to Meeli Eelma, Water Park Manager, when it comes to their customers, they spare no expense.

“We certainly won’t start saving at the expense of our customers,” Eelmaa said. “We cannot close our saunas or our slides earlier. We are not going to start telling our customers that you can only spend an hour in the sauna or an hour on the slides. If our opening hours are displayed, then customers can use [our facilities] at their full value.”

While the manager of the water park worries about high energy bills this fall and winter, the company nevertheless finds that it can no longer reduce its energy consumption.

“When Kalev Spa reopened after extensive renovations in 2019, the most important things had already been done – the lights all turn off automatically at night, i.e. everything is automated,” Eelmaa explained. . “And of course what we can do is be aware that we use less electricity in the office. [Kalev Spa’s] hotel rooms, as soon as someone pulls out the card from their location, the power supply [in their room] is cut.”

Year on year, electricity costs at the Kalev Spa water park and Selver supermarkets increased by more than 60%.

Selver’s biggest cost driver is its refrigeration systems and hot food counters, which account for around four-fifths of the supermarket chain’s electricity consumption.

“When renovating our stores and opening new stores, we have introduced refrigeration systems that reduce energy consumption by 30-40%, but it is a bit unrealistic to [replace them all] immediately in all of our existing stores,” said Kristjan Anderson, Selver’s Commercial Accounting Manager.

The complete modernization of the equipment of all Selver stores can be spread over a period of five to six years.

The city of Tallinn is also working on the implementation of smart solutions. For example, most of the year, twilight sensors regulate public lighting in the Estonian capital. Each year, the city also continues to replace old light fixtures with LED lights.

“This year alone we are investing 5.5 million euros in the replacement of street lighting, playgrounds, kindergartens and wherever we are renovating larger properties,” the deputy mayor said. from Tallinn, Vladimir Svet (Center).

Nevertheless, Tallinn does not intend to leave a single city street in the dark.

“Our principle is that street lighting is safety,” Svet said. “If we want people to go out and feel safe, our streets need to be well lit. And so far we’ve managed to avoid having to dim street lights anywhere.”

The deputy mayor noted that Tallinn intends to completely switch to LED lighting within four to six years.
