The Business Context

The Swiss electricity grid is characterised by increasing fluctuations between production and consumption values due to the growing amount of electricity sources. Wind and solar power, coupled with changing weather conditions make forecasting of electricity production a very complex process. Often, electricity is available when it is not immediately necessary and vice-versa.

Swisscom Energy Solutions offers a simple and reliable solution that connects small – as well as large-scale commercial and industry – consumers, in an intelligent storage network. Branded Tiko, the solution is designed to link-up residential heating systems to the network and use the storage capacity to balance out fluctuations in the electricity grid by slightly adjusting the heating cycle of anything from heat pumps, electric heating systems to night storage and hot water boilers.

Following a previous successful engagement with Swisscom, iQuest joined Tiko’s engineering team to develop a bespoke software solution for one of the network’s main devices. This allowed the company to bring the product to market, and in the process, build one of the largest smart grids in the world.

The Solution

Tiko is based on a complete control system, equipped with sensors and transducers, and consists of two modules: M-Box, a steering module designed to receive and send information to back-end system and K-Box, a device responsible for measurement and execution.

One of the project’s goal was an agile solution with specific time resolution of 1 second, meaning that in order to assure the grid’s overall success, data analysis, device state estimations and control actions were all required to happen in a very short timeframe.


During peak hours, the software evaluates power consumption through electrical impulses and sends data to the steering module, then helps shift the load to times when customers are using less power by controlling the devices.


Working with Tiko, iQuest helped architect an embedded solution for the measurement module, which comprises an integrated meter and a switch, and is able to communicate via the existing electrical lines within the user’s home. During peak hours, the software evaluates power consumption through electrical impulses and sends data to the steering module, then helps shift the load to times when customers are using less power by controlling the devices.

Starting with the development phase, the solution was framed innovative due to the way power was easily measured and transmitted through encrypted Power-Line Communication technology, capable of high data security and reliability. Implementing the solution was a joint effort, using a state-of-the-art environment that assured simulation and testing capabilities, in order to provide an efficient and reliable solution.

The Business Impact

Tiko was launched in October 2014, connecting more than 4,500 households to the first active smart grid in Switzerland and one of the largest in the world. Gaining such measurements and control, has enabled Swisscom Energy Solutions to fulfill their vision by enabling grid management in real time while allowing customers to benefit from potential savings, a more secure power supply and transparency with regard to electricity consumption.

Key benefits:

  • Smart Metering
    Independent device measurement according to individual attributes and consumption behavior.
  • Extended Security
    Safe data reliability with encrypted PLC technology.
  • Dynamic Performance
    Multiple-capabilities in receiving and executing control commands from the server.
  • Efficient Control
    Full control for the customer over device consumption patterns.
