Delta Green becomes first Czech supplier to offer household ancillary services

Energy startup Delta Green has launched a platform that enables Czech households to participate in ancillary services.
With the platform, and according to the needs of the Czech power grid, households will be able to supply or consume electricity in short time intervals to reduce their energy costs and balance the energy system.
In cooperation with the Czech transmission system operator ČEPS and Nano Energies, Delta Green successfully certified their 1MW aggregation block, which consists solely of households. This makes it the first energy supplier to offer end customers the opportunity to participate in ancillary services.
Delta Green is launching this innovation almost a year after it, together with ČEPS, became the first in the Czech Republic to test and verify that households can be involved in the management of the electricity system under domestic conditions.
The supply or consumption of electricity from the grid for ancillary needs usually lasts only a few minutes, with activations occurring on average several times a day. This does not limit the normal operation of households in any way. All households with standard photovoltaics with battery storage can participate.

Explaining in a release was Delta Green co-owner Jan Hicl: “Flexible electricity consumption is a new concept and approach for 99% of people.
“Initial uncertainty quickly disappears once people realize that the service does not limit them in their normal functioning and instead brings financial benefits. Creating a platform where people can transparently see in real-time what is happening with their electricity and why was also one of the biggest challenges we had to overcome.”
“A family of four in a house pays around €1,450 ($1,667) annually for energy. With us, their costs can now decrease by up to a third. They can save up to €40 per month on electricity.”
Delta Green is also collaborating with Nano Energies on the operation of the service, from which it separated a year ago and which is currently the largest flexibility aggregator in the Czech Republic. Now both companies have joined forces and know-how again to open this new path to Czech households.
Said Martin Kašák, director of the energy market section at ČEPS: “Aggregators are becoming an increasingly important group of providers of power balance services, which are essential for the reliable and safe operation of the electricity system.
“The involvement of households further expands the possibilities of flexibility aggregation, and can thus increase competition in the ancillary services market, which will be reflected in pressure on their price.”
Said Tomáš Mužík, director of Nano Energies CZ: “Flexibility in energy is the key to more efficient use of renewable sources and grid stability.
“The possibility of involving households in the flexibility market brings not only savings on electricity bills but also higher energy self-sufficiency. Cooperation with Delta Green is a logical step that allows extending the benefits of aggregation to the household segment.”
