本論文は、タシュマルニシュタ揚水発電所（PSHPP）の収益性向上のための長期電力購入契約（PPA）の可能性を分析する。300MWの太陽光発電所から20年間、32€/MWhで電力を調達する契約を想定し、PV*SOL premiumを用いて発電量を時間単位でシミュレーション。提案された運用レジームでは、6週間連続で太陽光発電中に10時間の揚水運転を行い、その後1週間は9時間の揚水と市場価格がピークとなる夕方に7時間の発電を行う。時間単位の分析により、再生可能エネルギーの最適活用による経済的持続可能性の改善を評価する。

This paper analyzes the potential of a long-term Power Purchase Agreement (PPA) to enhance the profitability of the Tashmarunishta pumped-storage hydro power plant (PSHPP). It models a 20-year agreement for 300 MW PV electricity at 32 €/MWh, simulating hourly generation with PV*SOL premium. The proposed regime involves ten hours of pumping during PV production for six weeks, followed by one week with nine hours of pumping and seven hours of generation during peak evening prices. The hourly analysis assesses technical and economic benefits of optimal renewable energy utilization.

📄 Abstract（原文）
This paper analyzes the potential of a long-term Power Purchase Agreement (PPA) as a mechanism to enhance the profitability of the Tashmarunishta pumped-storage hydro power plant (PSHPP). The study focuses on a 20-year agreement for the procurement of electricity from a 300 MW photovoltaic (PV) power plant, with purchase price of 32 €/MWh. The electricity generation of the PV power plant is modeled and simulated in PV*SOL premium on an hourly basis. Furthermore, based on data from the pre-investment study for PSHPP Tashmarunishta, the required electricity for water pumping and the expected electricity production from the PSHPP are analyzed. The proposed operational regime includes ten hours of water pumping during PV electricity production for six consecutive weeks, followed by one week with nine hours of pumping and seven hours of electricity generation from the PSHPP in the evening, when market prices are at their peak. The hourly-level analysis enables an assessment of the technical and economic benefits of this mechanism, examining the potential improvement in the economic sustainability of the Tashmarunishta PSHPP through the optimal utilization of renewable energy sources.
