In the case of solar energy purchases, consumers can achieve significant cost optimization due to the low cost of this technology. Moreover, solar power plants offer low volatility and predictability in energy production volumes. <\/li>\n<\/ul>\n<p>An additional important benefit of a <strong>PPA<\/strong> is its role in increasing the share of renewables in the national energy mix, contributing to a more sustainable and cleaner energy future.<\/p>\n<h3 class=\"green\">Types of PPA<\/h3>\n<div>\n<p><strong class=\"green\">Off-site Physical PPA<\/strong><\/p>\n<div style=\"text-align: center;\"><img decoding=\"async\" class=\"wp-image-11422 aligncenter\" src=\"https:\/\/rpower.energy\/app\/uploads\/2024\/03\/Rpower-schemat-3.jpg\" alt=\"\" style=\"margin-top: -80px;\" \/><\/div>\n<ul class=\"list\" style=\"padding-top: 10px;\">\n<li>This type of PPA can be entered into either with an end consumer purchasing electricity for their own needs or with an energy company engaged in electricity trading.\n<ul class=\"list\" style=\"padding-top: 10px;\">\n<li>In the first case, the end consumer directly benefits from the energy generated by the renewable energy installation.<\/li>\n<li>In the second case, the trading company acts as an intermediary, purchasing energy from the producer and supplying it to dedicated corporate clients.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>When the energy producer delivers energy to the consumer through the public power grid, additional settlement is required via balancing groups for both the power plant and the consumer.<\/p>\n<p>Balancing groups are operational structures within the power system that help balance energy production and consumption. Through this mechanism:<\/p>\n<ul class=\"list\">\n<li>The power plant (renewable energy producer) joins a balancing group responsible for supplying energy to the grid.<\/li>\n<li>The energy consumer joins their balancing group, which manages their energy consumption from the grid. <\/li>\n<\/ul>\n<p>This system allows for effective energy flow management, with any differences between projected and actual energy consumption and production settled at the balancing group level.<\/p>\n<ul class=\"list\">\n<li>Based on the Off-site PPA, the consumer pays for the energy and the guarantees of origin provided by the producer.<\/li>\n<li>Payments under such PPA agreements are calculated as the price multiplied by the volume of energy delivered each month.<\/li>\n<\/ul>\n<\/div>\n<div>\n<p><strong class=\"green\">Off-site Financial PPA (Virtual PPA)<\/strong><\/p>\n<div style=\"text-align: center;\"><img decoding=\"async\" class=\"wp-image-11429 aligncenter\" src=\"https:\/\/rpower.energy\/app\/uploads\/2024\/03\/Rpower-schemat-2.jpg\" alt=\"\" \/><\/div>\n<p>In this PPA model, known as <strong>vPPA<\/strong> (Virtual Power Purchase Agreement), there is no physical sale of electricity between the producer and consumer.
