Expected ROI of photovoltaic ESS project in Estonia 2030

Does Estonia have a rooftop PV system?

In Estonia, only one organization with CEC status operates a rooftop PV system (13 kW) on an office building, while Latvia has no operational energy communities yet. The focus was drawn to the roofs of residential multi-apartment buildings as the most accessible place for residents for the possible organization of CEC.

How much solar energy does the Baltic region have in 2022?

Between 2022 and 2024, the expansion of solar energy production across the Baltic region has exceeded even the most optimistic forecasts. By June of 2024, Estonia's total installed solar capacity reached 879 MW, Lithuania attained 1.2 GW, and Latvia added nearly 500 MW.

Why did PV systems increase in Latvia in 2022 & 2024?

Share of PV systems installed capacities. In Latvia, the installed solar photovoltaic (PV) capacity in single-family homes significantly increased in 2022 and 2024. This growth was largely driven by the availability of state support programs, the introduction of a net metering system, and rising electricity prices .

What is the largest electricity generation plant in Estonia?

At the moment, the largest electricity generation plant in Estonia is the 300 MW Auvere energy block and the most powerful external connection is the 650 MW Estlink2. HHI is the Herfindahl-Hirschman Index, which varies between 0–10,000, and the highest value of which characterises the greater dependence of the gas market on one gas seller.

What is the estimated rooftop PV energy production potential for 2022 – 2060?

In research geospatial methods and a high-resolution Building Integrated Solar Energy (BISE) supply model were used to estimate the rooftop PV energy production potential for the time period 2022–2060. Using the results of BISE , the estimated rooftop PV potential for EE is 6 TWh, LT 27 TWh, and LV 12,9 TWh.

What is the estimated rooftop PV potential for EE?

Using the results of BISE , the estimated rooftop PV potential for EE is 6 TWh, LT 27 TWh, and LV 12,9 TWh. The authors have developed a clear geospatial methodology, utilizing the latest EU building stock spatial data to accurately quantify the roof area available for PV system installations.
