As Poslovni Dnevnik/Darko Bicak writes, the energy sector is going through an extremely turbulent period that is deeply affecting both companies and regular households. Rising energy prices, the war in Ukraine, the need for decarbonisation and the need to digitise everything have made the need to find more innovative and sustainable solutions much, much more urgent. System optimisation, flexible consumption, the general reduction of the human carbon footprint and the reduction of business costs for companies and households are all pressing issues.
An innovative solution has been put forward by Nano Energies Croatia, a daughter company of the group of the same name from the Czech Republic, which is otherwise the first Croatian company to which HERA issued a license to carry out energy aggregation activities. It is a business model of a kind of “energy consulting”, i.e. energy management that can save companies 10-20 percent of their electricity costs, and is financed according to the well-known ESCO model.
Ultimately, Nano Energies Croatia plans to offer Croatian users an electricity storage service in the foreseeable future. The service they’re bringing to the Croatian market focuses on smart management and the overall flexibility of energy use. In practice, this means that it offers companies and electricity producers the possibility of managing their own consumption and production of electricity in order to reduce their business costs and profit from the movement of electricity prices on short-term markets. At the same time, the flexible management of production and/or consumption benefits the entire power grid and helps prevent interruptions in the supply of individual parts of the grid.
As explained by Dominik Maricevic, the manager of Nano Energies Croatia, given the accelerated decentralisation of the Croatian power system, the activity of aggregation has become an extremely important part of it.
“The unstable production of renewable energy sources has brought a challenge to the management of power systems. Frequency fluctuations within the power grid must be minimised to keep the grid stable. An independent aggregator with its distributed assets can play a key role in smoothing out such fluctuations. Therefore, our task is to create a network of small producers, consumers, as well as electricity storage tanks, so that they can react at any time and “offer” stability to the power system, but at the same time ensure access to profitable balancing energy markets. In this way, we’ll manage to both speed up and reduce the costs of the energy transition for Croatian users, and at the same time create the proper preconditions for the connection of new renewable energy sources to the electric power system,” explained Maricevic.
Stanislav Chvala, CEO of the Czech technology company Nano Energies, also emphasised that their license to operate on the Croatian market opens up numerous completely new opportunities for them.
“With flexible management, we can increase our customers’ income by up to several tens of percent. Experiences from Western markets shows us that flexibility aggregators replace fossil fuel and nuclear power plants and enable the transition to sustainable energy. We can use the potential of the electricity that would otherwise remain unused. We can adjust consumption and production so that the customer produces electricity when it is the most expensive, and consumes it when it’s the cheapest. The customer themselves doesn’t notice this during operation, because everything takes place automatically, and at the same time contributes to the stabilisation of the network without the need to include coal-fired power plants in balancing the system,” said Chvala.
Reconstruction of the network
He added that Europe has already started to rethink and rebuild its overall energy network and it is clear that in the coming years there will be a huge increase in the use of RES.
“Historically, the time when the wind doesn’t blow or the sun doesn’t shine was compensated for by gas and coal power plants, but this is an increasingly unsustainable situation for geopolitical reasons, as well as the need to preserve the environment. We have to look elsewhere for flexibility,” he concluded.
