On average, prices tripled compared to pre-pandemic levels in 2019, despite stable demand. This trend, though less pronounced in other European markets, has raised concerns about the efficiency and competitiveness of wholesale electricity markets. This study investigates the bidding behavior of non-pumped hydropower plants in the Iberian market, employing a merit order model based on real data from 2019 to 2021. The analysis reveals a clear mismatch between hydropower bid prices and actual production costs. Although this practice is legal, it conflicts with the European Union's goal of promoting fair competition within the internal electricity market.</p><p>Our findings suggest that aligning hydropower bid prices with 2019 levels could have reduced annual market costs by approximately 2324 million euros under a moderate scenario. This indicates substantial potential for cost savings and improved integration of hydropower. However, this strategy also benefits companies that own these hydropower plants, as they often possess large portfolios and can capitalize on increased market prices through other plants, particularly renewable energy units, which offer electricity at very low prices and have a high likelihood of being dispatched.</p><p>Furthermore, the study highlights regulatory gaps allowing hydropower plants to price low-cost energy similarly to thermal plants, raising consumer costs and distorting market dynamics. These findings emphasize the need for stronger regulatory oversight and reforms to prevent excessive price inflation by hydropower, which plays a critical role in renewable energy integration and grid stability. Policymakers must ensure fair pricing while compensating hydropower plants for their flexibility and essential contributions to the energy system.</p></div>","PeriodicalId":11546,"journal":{"name":"Energy Strategy Reviews","volume":"55 ","pages":"Article 101517"},"PeriodicalIF":7.9,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2211467X24002268/pdfft?md5=f14cb3d9cb65d5e348cf31eb1f6ea48f&pid=1-s2.0-S2211467X24002268-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142096682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, outcomes depend on the extent of domestic supply chain content in manufacturing heat pumps, on installation costs to households, on how and where government revenues accrue. Moreover, the relative importance of drivers varies over time. For example, higher purchase and installation costs may support a greater initial stimulus via producer and domestic supply chain gains, despite the greater cost burden on households.

This is achieved by conducting a systematic literature review and qualitative analysis of recently published research papers. The study uses bibliographic, co-citation, and keyword analysis to identify recent trends in global ESCO research. The results show that the aspects of ESCO that most studies have focused on are business models, market development, barriers, and drivers of ESCO, stakeholders in ESCO, energy performance contracts, and risk management in ESCO. In addition, the study identifies two main research gaps in ESCO research. These are public-private partnerships in ESCO programs and the development of a harmonised measurement and verification method for energy savings as the research gaps in ESCO studies.

This work investigates the integration of energy efficiency, financial feasibility, and environmental considerations, offering a strategic roadmap for expanding distributed PV systems within an emerging local policy framework. The findings indicate that regular performance monitoring is crucial, particularly in arid conditions. Semi-annual maintenance is effective in detecting early failures and extending the system's lifespan, while bi-weekly cleaning enhances cost efficiency and energy savings in arid climate areas. The main findings indicate that initial rooftop PV utilisation rates range from 21 % to 49 %, with energy savings differing by building type: 16–21 % for campuses and 43 % for residential buildings, depending on the mitigation of rooftop obstacles and the dynamic of electrical self-consumption. Furthermore, proper design and maintenance can improve the performance ratio to 77.00%–84.27 %. Likewise, economic feasibility hinges on cost and energy yield, with a mean LCOE of $0.0445/kWh.
