Frequently Asked Questions

Sunterra RE is a Bulgarian company specializing in the construction, development, and management of its own renewable energy assets. The company develops solar, wind, hybrid, and BESS projects in Bulgaria.

Sunterra RE invests in the development and construction of energy assets that it owns and manages long-term. The company combines energy generation and storage with active participation in energy markets.

The power plants in Galabovo, Kaloyanovo, Karlovo, and Pleven create long-term employment and stimulate the local economy by working with suppliers, subcontractors, and consultants from the region. Sunterra RE builds relationships with communities based on cooperation and transparency, because the region’s prosperity and sustainable business go hand in hand.

The four power plants, with a combined capacity of 534 MW, generate electricity for more than 200,000 Bulgarian households.

Sunterra RE’s operations save over 1 million tons of carbon emissions annually. This improves air quality and the living environment in the communities where the power plants are located.

A photovoltaic (PV) power plant is a solar energy facility that converts sunlight into electricity using solar panels and inverters. These plants are developed as energy assets designed to generate electricity for the grid and energy markets.

Solar power plants provide reliable and cost-efficient electricity generation while reducing carbon emissions. As energy assets, they contribute to long-term energy security and support the transition to sustainable energy systems.

Battery Energy Storage Systems (BESS) are energy assets that store electricity for later use. They enhance flexibility, optimize the performance of renewable energy assets and enable efficient participation in energy markets.

Solar tracking systems are technologies that adjust the position of solar panels to follow the sun’s movement. This increases energy generation and improves the performance of photovoltaic energy assets.

A hybrid project is an integrated system that combines two or more energy sources (most commonly wind and solar) with energy storage technology (BESS). The goal is to improve the efficiency, flexibility, and overall performance of energy assets.

A PPA (Power Purchase Agreement) is a long-term contract for the purchase and sale of electricity, entered into directly between a producer (e.g., the owner of a solar power plant) and a buyer (a large industrial consumer or an energy trader). Under this agreement, the parties agree on a fixed price per megawatt-hour (MWh) for a period of typically 10 to 15 years.

Energy assets are infrastructure facilities for the generation, storage, and management of electricity that create long-term value.

Renewable energy is generated from natural sources such as the sun, wind, and water, which are constantly replenished.

The electricity grid is the system that transmits and distributes electricity from generators to consumers.

Grid connection is the process of linking an energy asset to the electricity network.

Flexibility is the energy system's ability to respond to changes in supply and demand.

Decarbonization is the process of reducing carbon emissions in the energy sector.

A carbon footprint measures the amount of CO₂ emissions generated by a given activity.
