Starting on April 1, the Romanians’ monthly electricity invoices will grow by 4.5 per cent, realitatea.net informs. The price hike follows the introduction of a contribution meant to support the producers of green energy. “The price that household consumer will pay each month will grow by RON 1.8 per 100 kWh, in order to support the production of energy in high efficiency cogeneration units. This is not a hike in the price of energy, it represents supplementary costs,” Economy Ministry sources stated. The current tariff for 100 kWh, the average amount of energy consumed per household per month in Romania, stands at RON 40. The collected money will be used to invest in high efficiency cogeneration units that consume small amounts of raw materials and create less pollution. Their production costs are high because they use more expensive technologies. The value of the contribution has been established through the order of the President of the Romanian Energy Regulatory Authority (ANRE). The contribution will be offered to the producers of electricity and heating each month from 2011 to 2023, as a bonus meant to support the cogeneration sector.
