En septembre dernier, la start-up Plentify a remporté l'opportunité de participer à la finale internationale d'EDF PULSE AFRICA qui se tiendra le 21 novembre prochain à Paris. Plentify est une start-up sud-africaine spécialisée dans la conversion de chauffe-eau thermiques équipés de batteries thermiques connectées au réseau électrique. Ils chargent intelligemment lorsque l'électricité est abondante sur le réseau. Pour ce faire, les concepteurs installent sur l’ensemble du dispositif Internet des contrôleurs d’objets, une application mobile et un moteur utilisant l’intelligence artificielle, afin de pouvoir allumer et éteindre le chauffe-eau en fonction des demandes des utilisateurs. La solution proposée par Plentify permet de réduire la dépendance à une production non écologique et très coûteuse. Son fondateur : Jonatan Kornik alias Jon, un génie sud-africain originaire de Cap-town, doté d'un master en finance, d'un MBA obtenu à la Columbia Business School à New York. Focus.

PLENTIFY, the South African start-up that turns a water heater into an intelligent thermal battery

South Africa: Interview with Jon Kornik, founder of start-up Plentify

Plentify is a South African start-up specializing in the conversion of thermal water heaters equipped with thermal batteries connected to the power grid. They charge intelligently when electricity is abundant on the grid. To do this, designers install on the entire Internet device controllers, a mobile application and a motor using artificial intelligence, to turn on and off the water heater according to user requests. The solution proposed by Plentify makes it possible to reduce the dependence on a non-ecological and very expensive production. Its founder: Jonatan Kornik aka Jon, a South African genius from Cap-town, with a master's degree in finance, an MBA from Columbia Business School in New York. Focus.

In the midst of the energy crisis, South Africa must green its bouquet

Repeated power cuts, increasing demand for energy, consumer discontent, industrial concerns, the South African government faces a national challenge! Thus, the authorities plan to produce less coal, a lot of wind and a good dose of solar. In the new energy plan presented on October 18, 2019, the government plans to produce 20 gigawatts (GW) of solar and wind energy by 2030. It is with this in mind that Jon Kornik, after consulting in the sector Mines, Transport and Logistics created Plentify in January 2017. A way of mixing its skills with a project that really impacts the environment.

South African households in cities suffer from the high cost and irregularity of energy services, Plentify faces this problem

South African households in cities suffer from the high cost and irregularity of energy services, Plentify tries to deal with this problem with a household appliance present in most homes but whose potential remains untapped, it is of the water heater.

"With Plentify and a water heater connected to the Internet, it's starting again!"

"With Plentify, once the water heaters are connected to the Internet, things get going again, they are more operational to achieve two objectives: save 30 to 50% of the costs of heating water and connect the water heaters to make a central virtual electric," explains Jon Kornik. One way to eliminate the need for polluting electricity, expensive and irregular on the South African power grids.

Plentify is a start-up that brings together computer engineers, data scientists, software engineers, hardware engineers, energy specialists and other profiles whose CV is impressive. Jon Kornik is really proud of his team.

Plentify horizon 2025

Plentify aspires to deploy its device to 500,000 homes (owners of large properties) over the next five years and create the equivalent of 8,000 full-time jobs. Jon Kornik, the young boss of Plentify entered the start-up at the third edition of the contest organized by EDF Pulse Africa and last September, they won the opportunity to participate in the international final to be held on November 21 in Paris.

This third edition focuses on encouraging initiatives addressing the specific needs of African people, particularly those in rural areas, who are generally the most affected by electricity supply problems. As he says when quoting Sun Tzu: "Opportunities multiply when they are seized". Answer on November 21st!


EDF Pulse Africa is a competition launched by the EDF group's international management to reward African start-ups and SMEs with fewer than 30 employees. The winners of the 2019 edition will receive envelopes ranging from 5 to 15 000 euros to finance their activities, including the implementation of the presented solution.
