Smart Electricity

Smart Electricity does not require additional investments but helps shorten the payback period for investments made in production equipment.

The financial gain depends on various factors - consumption, production, and storage. Additionally, the financial gain is influenced by the configuration of the devices and the seasonal specifics of production – low in winter, high in summer. Taking all these variables into account, the financial gain can range from 5% during the winter period to 30% during the summer period.

Alexela Smart Electricity also takes into account the customer's consumption habits.

Alexela's interest lies in ensuring that our customers can receive all energy services from a single source. This way, we can offer better service to our customers, thereby increasing customer satisfaction.

Smart Electricity limits or stops selling electricity to the grid when selling is no longer beneficial for you — that is, when the exchange price falls below the combined total of the margin deducted from sales revenue and Elering’s balancing capacity cost.

Put simply: if the revenue earned for each kilowatt-hour fed into the grid no longer covers the costs related to selling electricity, then selling it is no longer reasonable. During such hours, Smart Electricity will, where possible, direct the energy to a battery or limit production in order to avoid losses.

The balancing capacity cost is Elering’s fee used to finance the frequency reserves that keep the electricity system in balance. From 1 January 2026, this fee also applies to energy fed into the grid by micro-producers. For production, the fee is €3.73/MWh, or 0.373 cents/kWh (excluding VAT). More detailed information and the current rate can be found on Elering’s website.

Yes, you can. Smart Electricity does not require an energy storage solution — you can join the service even if you only have a solar park.

In that case, the service does not direct energy to a battery, but instead limits or stops selling electricity to the grid during hours when the exchange price is low or negative. It is important to note that only sales to the grid are limited. Your own consumption is always covered first from solar energy, and the energy produced continues to be used for self-consumption. This helps you avoid selling electricity at a loss and allows you to get the maximum benefit from your solar park.

For the service to work, the solar park must have a remotely readable meter (smart meter) installed.

If the capacity of your solar park exceeds 50 kW, it is also worth considering the Alexela Virtual Power Plant (VPP) service. This goes one step beyond production control: in addition to limiting sales during low-price hours, VPP directs available capacity to frequency and reserve markets, helping create even greater value from your solar park.

Yes, joining requires an Alexela stock market package and a production contract.

Because with a fixed electricity package, there is no benefit from managing the solar power plant.

Yes, Smart Electricity learns from your consumption habits. In the short term, the service can be paused if necessary, and it also functions during the so-called learning phase, during which the parameters related to consumption are still becoming more accurate.

The terms and conditions are available when you enter the Smart Electricity platform.

Smart Electricity may need two to three weeks to learn your consumption patterns.

The benefit of Smart Electricity does not appear on the bill – it is visible in the Alexela app.

You can access it with Smart-ID, ID card, and Mobile ID.

Yes, business customers can also join, but please write to tarkelekter@alexela.ee  in advance so we can enter your information.

Yes, Smart Electricity helps limit grid sales during negative hours on the stock market.

A SolaXCloud username and the inverter serial number are required.

A separate additional device is required to integrate Deye devices. For more information, please write to tarkelekter@alexela.ee.

For information about Pixii battery integration options, please write to tarkelekter@alexela.ee.

Alexela itself does not sell or install solar panels nor offer battery solutions. For battery solutions, we recommend contacting the partner who established your solar park.

Smart Electricity does not perform more than two charge/discharge cycles per day, which does not reduce the lifespan of the batteries, as this is a standard parameter for most battery types.

The inverter is not reconfigured to use the Smart Electricity service; devices are controlled without changing the inverter's settings.

Additional equipment is needed if the existing set of devices does not allow for device control. For suitability of equipment, please contact tarkelekter@alexela.ee 

It is recommended to choose a two-tariff package to take advantage of cheaper charging at night.

You can find the network package and production capacity limit in the network contract of your electricity network company.

For Elektrilevi, the network package and production capacity limit can be found in Elektrilevi's self-service on the network contracts and packages page. When you activate the address of the consumption site, all contract details will appear, or you can download the PDF of the electricity producer contract, which contains all the necessary information in one document.

For other electricity network companies, please consult their customer service for the relevant information.

At the moment, we do not offer participation in frequency markets through Tark Elekter, but we are actively developing the service. If we add the possibility to participate in frequency markets, we will inform customers separately. Business customers can connect their solar park to the Alexela Virtual Power Plant, through which the solar park would also participate in the frequency market.

According to Elektrilevi’s rules, generation units with a capacity of over 15 kW must feed at least 95% of their contracted generation capacity into the grid during at least one 15-minute period in a calendar year. Since Tark Elekter limits production or directs energy into the battery only when the exchange price is negative or very low, your plant always operates at full capacity during periods of normal and high electricity prices.

In practice, the risk of incurring the underutilisation fee is almost non-existent for the following reasons.

The algorithm takes grid requirements into account
The Tark Elekter control system is configured to automatically ensure the necessary full-capacity production periods during the year precisely in the hours when the exchange price is most favourable for the producer.

There are enough high-price hours
In Estonia, there are hundreds of hours during the year when the electricity exchange price is high enough. During these periods, the system never limits production and instead directs all possible energy into the grid. As a result, Elektrilevi’s 95% requirement is usually fulfilled already during the first sunny days of spring.

Important note in the case of high self-consumption
If your generation plant is configured in such a way that you consume or store in batteries (even without Tark Elekter) almost all of the energy produced, and at least 95% of the contracted generation capacity never reaches the grid, switching off smart control will not solve the issue.

In that case, the reasonable and correct solution is to reduce your contracted generation capacity with Elektrilevi to match the actual maximum capacity fed into the grid. Reducing generation capacity with Elektrilevi is free of charge.
