The market

As of April 1st 2019, the small-scale feed-in tariff (FiT) as well as the export tariff to new installations will end. The FiT was a scheme designed to promote the uptake of small-scale renewable and low-carbon electricity generation technologies, including mainly solar PV, but also wind power and cogeneration.

The changes in legislation heavily affect small-scale generation of electricity, such as solar PV on rooftops. PV systems generate the most energy normally at a time when household demand is typically at its lowest, i.e. during the day when the sun is shining and the occupants are out for the day. Under the FiT scheme, those surpluses could be exported to the grid at a financially attractive rate.

The end of the FiT scheme impacts both companies that are selling the solar PV and storage as well as end customers who are interested in acquiring it. Moreover, the overall decarbonisation targets are in danger as the installation of distributed energy resources is slowed down. 

Our solution for the post-FiT-time

Lumenaza’s scalable and highly automated utility-in-a-box software and services enable offering PPA even to small-scale generation. Moreover, the implementation of time of use tariffs becomes possible as well. In such a way, Lumenaza does not only mitigate the impact of the end of FiT, but opens the path to a subsidy free green energy world.

Lumenaza flexible platform and services enabled a broad range of new business models helping utilities, energy producers and prosumers to innovate in changing regulatory environments. It helps market players in accelerating time to market and enabling a portfolio of value propositions, which can be stacked to maximise value to the end customer.

Our value proposition

Export PPA

Together with Lumenaza, market players are able to mitigate the impact of the FiT export closure. Lumenaza is able to establish and manage the PPAs even for small generation capacities in a cost effective and operationally efficient manner. While end customers benefit from getting a payment for the export, utilities and project developers profit from having attractive offers in order to continue acquiring customers. Power Purchase Agreements are independent from public authorities or government subsidies. To date, PPAs have been mostly used to contract large scale generation. 

Time of use tariffs

Lumenaza enable market players to implement smart time of use tariffs with engaging visualization function to motivate customers to adjust their usage profile to reduce their bills, whilst contributing for the grid balancing. The combination of time of use tariffs with PV systems and batteries increases the potential benefits, as customers are able to store their electricity and use it in times of high demand. Moreover, they are able to increase self-consumption and thus reduce their bills again. Market players have the opportunity then to innovate in bundling hardware, electricity and services, increasing their competitiveness.

Energy communities

Lumenaza has been enabling geographically bounded and virtual communities, enabling sharing of electricity among locals, as well as enabling traditional retail suppliers and battery manufactures to offer their end customers new tariff options and bundles. Experience shows that community approaches help to increase customer loyalty.


Lumenaza support business and operational models to enable residential customers to participate in the flexibility trading growing opportunity. With the high number of heat pumps, batteries installed and EVs, flexibility becomes an increasingly important feature to balance energy supply and demand. New business models can be created by incentivizing customers to use the energy in peak-production times. When the energy is needed again, the aggregated flexibility can be marketed again.
