Prague, 14 November - Delta Green is the first on the Czech market to launch the long-awaited flexibility trading service for households. The service allows people to receive financial rewards for their electricity consumption or production, help balance the grid and shut down coal-fired plants sooner. Delta Green also plans to offer the service to energy suppliers abroad.
"It’s simple. In our application, clients indicate that they want to start harnessing flexibility. Then, at the right moment, we remotely activate, for example, the discharging of their photovoltaic system battery," says co-owner and Chief Product Officer at Delta Green, Jan Hicl. "The customer receives a reward for flexibility, i.e. the ability to shift their consumption or production of electricity over time," Hicl adds, explaining how the reward works.
The launch of household flexibility trading was for a long time considered an exceptionally difficult, if not impossible, task by energy experts. The innovators at Delta Green have shown that even small resources such as households can effectively contribute to grid balancing.
In customers' households, Delta Green currently utilizes batteries and photovoltaics. However, they will also soon be able to manage the charging of electric vehicles and smart homes using systems such as Loxone or Home Assistant. With an increasing number of smart devices, the volume of flexibility that households can offer will increase. Along with that, the reward for shifting the use of this energy volume over time will increase as well.
"According to our analysis, the untapped flexibility potential in Czech households last year was approximately 6,000 megawatt hours. Our service can be used by over 200,000 households that have smart meters and photovoltaics," notes Hicl. Delta Green has been testing the service with select customers since the second half of October. Results show that there were 100 activations in an average household, with the reward ranging from 4 to 15 euros, depending on the size of the photovoltaic system.
"We built this service with the idea of it being used by electricity providers in other countries as well. Look at Germany. According to a recent study conducted by Agora Energiewende, e-cars, heat pumps and residential storage systems will be able to delay around ten percent of the required annual electricity demand in Germany by 2035. This equates to 100 terawatt-hours, meaning that demand-side flexibility will save the German economy around 4.8 billion euros. We’re ready to help customers and electricity providers everywhere to start utilizing this potential,” explains Hicl.
Delta Green is sprinting toward fulfilling its vision of becoming a European leader in household electricity consumption. Its business plans are supported by three prominent investment funds.
