Cross-subsidies for both energy producers and consumers are another widespread mechanism. In Georgia, for instance, electricity producers sell electricity to the grid at differentiated tariffs that ensure lower costs to end consumers, but in practice provide cross-subsidies from cheap hydropower generation to higher-cost natural gas generation. Another example is Belarus, where commercial consumers of natural gas, electricity and heat pay a premium in the tariff put in place to cross-subsidise the tariff for households. Furthermore, heat tariff for households is cross-subsidised not just through the higher heat tariffs for commercial users, but also through tariff for electricity, since Belarus co-generates a lot of its heat and electricity.
