To determine which of these technologies will develop in the future and how the DH system will look, heat tariffs of all four technologies are compared.
Heat tariffs are taken as the main driving force when making decisions about which of the four technologies to install after the old ones have reached the end of their technical lifetime.
Changing the heat tariff from its current planned level of 2.7p per kilowatt hour would require the RHI regulations to be amended and submitted to parliament for approval.
The heat tariff of the solar technology remains competitive from the 2023 year.
The heat tariff calculation methodology based on the heat calculation methodology developed by the Public Utility Commission of Latvia [34].
The heat tariff was used as the main indicator to determine the pace and structure of the technology change.
This difference is accounted for in the fixed part of the heat tariff and is translated into additional income in the case of heat pumps.
The heat tariff is the element that determines whether the reinforcing or the balancing loop will be the stronger; it actually determines which way the DH system will develop towards fossil technologies or towards 4GDH system.
However, many of the KWILLT participants did discuss heating, fuel tariffs and schemes such as Warm Front.
Heating and electricity tariffs were doubled, with bigger increases promised later this year.
