The maximum co-financing for micro-installations with additional components is up to PLN 20,500. For new prosumers entering the net metering system, a subsidy of up to PLN 4,000 is provided for the photovoltaic installation itself. If the prosumer decides to make additional investments to increase the self-consumption listed in the program, the subsidy for photovoltaics can amount to PLN 5,000. Additionally, up to PLN 5,000 for a heat storage facility or PLN 7,500 for an electricity storage facility. An additional 3000 PLN can be obtained when installing HEMS / EMS systems, but only on the condition of purchasing electricity or heat storage. Individual grant amounts cannot exceed 50% of the costs incurred.
Mysterious HEMS/EMS Concepts
The maximum amount of co-financing in the program – 20.5 thousand. PLN – can be granted to prosumers who really take the issue of increasing self-consumption of energy produced in the facility seriously and, in addition to the storage itself, also focus on energy management, i.e. HEMS or EMS systems.
HEMS, i.e. home energy management system is an energy management system for the whole building. Thanks to it, it is possible to optimize the consumption of electricity and heat within the framework of all the energy needs of the building. In turn, under the term EMS – ang. energy management system is the management of energy from the photovoltaic micro-installation itself. Such a system aims to allow intelligent control of the flow of energy from a photovoltaic micro-installation between the current consumption of devices using electricity, the storage of electricity or heat, or cooling needs, according to established priorities. The objective is simple: the green energy produced must be used in the household, then injected into the network.
In this context, individual items, such as smart plugs, are not eligible for co-funding. However, such components can be funded if they are one of the building blocks of the overall building energy management system (HEMS/EMS). So which systems are eligible for funding?
Hybrid inverter like EMS
A PV inverter is an essential component of a PV installation which, without this component, cannot function in a domestic PV installation. However, there are devices – hybrid inverters, which in addition to their basic task, that is, the conversion of direct current into alternating current, perform additional functions. Above all, the use of hybrid inverters makes it possible to supply the system with energy storage. The main advantage of using a hybrid inverter is above all increased self-consumption, since the excess energy produced can be stored in batteries for later use, and not immediately sent back to the grid. In addition, in the event of a power failure in the network, for example, as a result of a blackout, the hybrid inverter can ensure the operation of the most important devices in the building. Some hybrid inverters also allow intelligent energy management and it is this function that can bring them greater funding under the My Current 4.0 program, but under certain conditions.
The invoice is important
First of all, it should be pointed out that if an item is to be financed, not only in the My Electric program, but in any subsidy program, it must be mentioned on the invoice as the extracted element. This is perfectly understandable given the number of different components that can be funded. As we read on the program website, this is also a mandatory requirement due to the need to qualify individual items in the grant application builder through which applications are submitted to the My Current 4.0.
In order to benefit from increased financing under the EMS for a hybrid inverter, it is therefore necessary to separate the energy management system on the invoice. As we read in the questions and answers on the official website of the My Current program, in the case of a collective invoice, an additional clarification must be attached in the form of an attachment to the invoice. The attachment must be an integral part of the issued invoice and must specify the number of individual goods / services, the name and designation of the goods / services, the price of the individual goods / services – both per unit and in total.
We therefore know that it is important to indicate the possibility of energy management on the invoice. And the price then? After all, the investor is buying a device – a hybrid inverter. The National Fund for Environmental Protection and Water Management also has the answer – presentation of the corresponding calculation in a statement signed by the contractor or system vendor. As we read on the mojprad.gov.pl site, in this document (contractor/vendor) indicates the price difference between the hybrid inverter (purchased/installed device) and the price of a “standard” inverter (device of the same manufacturer without additional functions offered by the contractor/vendor) . The price difference will be treated as an eligible cost in the EMS category.
Therefore, when choosing a hybrid inverter from a given manufacturer, the prosumer must take into account that the entrepreneur must offer a non-hybrid inverter from the same manufacturer. In this case, it is worth paying attention to two more issues. Firstly, in this case, it is no longer possible to finance another energy management system. Second – the generated/consumed electricity monitoring function is not treated as energy management.
EMS and HEMS in the My Current program
We know that under certain conditions a hybrid inverter can qualify for funding, and what other devices can be considered HEMS or EMS? As we read on the official website of the program, the eligible cost for the purchase and installation of the energy management system HEMS / EMS * as part of the Mon Courant Priority Program of the National Fund for Environmental Protection and Water Management recognize (already mentioned) hybrid inverter/inverter or other device/controller/module characterized by the function of managing/optimizing the electrical flow in the building and possibly monitoring the electricity produced/consumed. Interestingly, as mentioned earlier, this last element is insufficient for a hybrid inverter to qualify as an energy management system.
