FuelCell Energy signs PPAs for two large projects in Connecticut

Power purchase agreements aim to secure long-term contracts between sellers and buyers, particularly in renewable energy transactions. However, successful negotiations for a fixed long-term price and energy volume while ensuring maximum utility for stakeholders remains a significant challenge. This paper introduces a comprehensive model for negotiating 24/7 power purchase agreements, focusing on hourly pricing to address deficits and surpluses throughout each day of the contract timeline. The model incorporates demand flexibility through battery storage, settling on the strike price using Nash Bargaining theory and optimal management of energy consumption relative to market price fluctuations. A soft margin support vector machine classification model determines the buyer’s maximum acceptable price. Moreover, Gaussian process classification is employed to calculate a probabilistic, risk-adjusted strike price, enabling a data-driven approach to power purchase negotiations. The proposed model’s performance is demonstrated through a detailed case study of Norway, illustrating how demand flexibility can significantly lower long-term power purchase agreement contract prices. The analysis of yearly price trends indicates that incorporating flexibility resources in long-term energy contracts may lead to a reduction in strike prices by around 25%. Moreover, such flexibility enhances demand-generation matching, thereby increasing renewable energy transactions within such agreements.

The electricity market in the UK has been reformed over recent years resulting in the introduction of ‘Contracts for Difference’ as an option for wind producers. They can use these contracts only if at the same time they enter into other market contracts, i.e., Power Purchase Agreements or participation in the wholesale market. Most wind producers prefer the option of holding a long-term Power Purchase Agreement with another party. However, these agreements do not always offer the best terms for a wind producer due to them selling energy at lower electricity prices than those of the wholesale market spot prices. In addition, direct participation in the wholesale market can lead to high imbalance costs for the wind producers. In this paper, we propose an optimal dispatch model solved via dynamic programming optimisation to examine these two different business cases for wind operators alongside the existence (or not) of subsidised Contracts for Difference. A case study with an onshore UK wind farm and a lithium-based battery is provided. The proposed methodology was designed flexibly, so that it can be applied to different wind farm and battery configurations, as well as energy market structures. It is found that it is not always more profitable for the wind operator to hold a Power Purchase Agreement with another party than owning a battery storage unit and trading wind energy directly into the wholesale market. The discount rate of the Power Purchase Agreements, the capital cost of the wind farm and the strike price of the Contracts for Difference are critical factors affecting the profitability of both business cases. In addition, if subsidies are totally removed from both of them, then these are no longer economically justifiable, unless significant reductions are achieved in the capital costs of wind farms and battery storage units. Lastly, we show that considering only the calendar life of the battery (and not the cycle life) leads to significant underestimation of the investment costs.

Managing volumetric risk of long-term power purchase agreements

Power Purchase Agreements (PPAs) enjoy great success in Europe. This is especially true of Green Corporate PPAs (GC PPAs), also known as Corporate Renewable PPAs, which are agreements under which a corporate customer agrees to purchase renewable electricity directly from the electricity producer, pursuant to the definition set forth in the 2018 Renewable Energy Directive (‘RED II’) (Directive (EU) 2018/2001 of the European Parliament and of the Council of 11 Dec. 2018 on the promotion of the use of energy from renewable sources (recast).). Nearly 14GW in PPAs were entered into in 2018 worldwide, of which 1.9GW in Europe (2017: 1GW) and approx. 8GW in the United States (2017: 2.4GW) (Europe Corporate Renewable, PPA Market Report 2018 – 2027.). Wind energy accounts for 85% of GC PPAs entered into in Europe to date, with solar energy accounting for the remaining 15%. This progress can be explained partly by an increase in energy demand worldwide, the companies’ willingness to reduce their carbon footprint and control energy costs, the need for clear and foreseeable price signals for investors and producers, but also the development of public support schemes for renewable energies (‘RE’).

This chapter examines power purchase agreement (PPA) structuring mechanisms to address project risks that manifest across renewable energy projects in several Asian countries. Using India as a case study, the chapter identifies the extent to which the standard PPA provisions address current prominent risks in the sector. It goes on to identify how existing provisions could be modified and newer structures could be included to ensure a more bankable PPA format. One key intended takeaway from this chapter is that the process of arriving at a standardised model for a PPA must be a constantly evolving one, taking into account the concerns of all project stakeholders, project risks and solutions across jurisdictions, to bring stability to the PPA models.

Humanity since its origins as a species has depended on energy for its existence and development. The various energy crises that have occurred have had major negative impacts on both the economic and social spheres. The current worrying world energy situation, characterized by a constant increase in demand, polluting emissions and rising prices of energy, as well as an inevitable depletion of fossil fuels, has in recent years generated a general awareness of the need to develop sustainable energy solutions. Currently, the high dependence on foreign suppliers for energy imports has put the accessibility and affordability of energy at risk, and States have had to develop numerous initiatives to protect consumers from volatile energy prices. In this framework, widespread energy production through renewable energy sources and the use of Power Purchase Agreements (PPAs) emerge as tools to achieve energy security and mitigate energy vulnerability and poverty. This research aims to contribute to this effort by making an approximation to the Cuban legal and institutional framework of PPAs. Cuba, in line with the current global energy context, is in search of energy sovereignty based on renewable energy sources. Throughout this article, it is intended to substantiate the need to regulate PPAs in the pursuit of sustainable energy development solutions. With the enactment of Decree Law 345 of 2019 for the promotion of renewable energy sources and efficient energy use and its complementary rules, the first regulatory foundations for PPAs have been laid. While the Cuban legal energy system has been making substantial progress regarding PPAs, it must still strive to be further perfected.

The Smart Energy Design Assistance Center assessed the administrative, technical, and economic aspects of feasibility related to the procurement and installation of photovoltaic solar systems on IDOT-owned buildings and lands. To address administrative feasibility, we explored three main ways in which IDOT could procure solar projects: power purchase agreement (PPA), direct purchase, and land lease development. Of the three methods, PPA and direct purchase are most applicable for IDOT. While solar development is not free of obstacles for IDOT, it is administratively feasible, and regulatory hurdles can be adequately met given suitable planning and implementation. To evaluate IDOT assets for solar feasibility, more than 1,000 IDOT sites were screened and narrowed using spatial analytic tools. A stakeholder feedback process was used to select five case study sites that allowed for a range of solar development types, from large utility-scale projects to small rooftop systems. To evaluate financial feasibility, discussions with developers and datapoints from the literature were used to create financial models. A large solar project request by IDOT can be expected to generate considerable attention from developers and potentially attractive PPA pricing that would generate immediate cash flow savings for IDOT. Procurement partnerships with other state agencies will create opportunities for even larger projects with better pricing. However, in the near term, it may be difficult for IDOT to identify small rooftop or other small on-site solar projects that are financially feasible. This project identified two especially promising solar sites so that IDOT can evaluate other solar site development opportunities in the future. This project also developed a web-based decision-support tool so IDOT can identify potential sites and develop preliminary indications of feasibility. We recommend that IDOT begin the process of developing at least one of their large sites to support solar electric power generation.

Pricing bundled renewable energy credits using a modified LCOE for power purchase agreements

Malaysia introduced Feed-in Tariff (FiT) in 2004 to incentivise renewable energy projects through the implementation of the National Renewable Energy Policy and Action Plan 2009 and the Renewable Energy Act 2011 (Act 725). Nevertheless, this FiT system failed to assist the country in increasing electricity generation from renewable sources. Later, auctions were introduced to boost the renewable shares, particularly solar photovoltaic power generation, after the quota for solar under the FiT were taken up. The tenders incorporated standard form of the contract along with a long-term Power Purchase Agreements (PPA) which induced for the lowest price for power generation and guaranteed access to the national grid. This measure is considered as an excellent instrument to expand the renewable energy sector. There has always been a question: whether abandoning FiT for auctions is a feasible choice in the interest of sustainable clean energy for sustainable development? The main objective of the present article is to investigate the implementation of auctions to support renewable energy development in Malaysia and to examine whether auctions could replace FiT. This study adopted a doctrinal and comparative approach. It concluded that competitive bidding is preferable to support mature technology and large-scale generations, while FiT should be sustained to support new technologies. The article has also identified several countries such as Germany and India, who have successfully implemented competitive bidding systems to support the aspiration to expand the renewable energy sector.

The world is undergoing a massive energy transition. Over the next decades, there will be radical changes in the way we produce and consume energy. The conventional energy infrastructure being set up now would be abandoned ever before their economic life is over. A quarter of India’s population have no access to electricity and our per capita consumption of electricity is very low at almost one third of world average with millions getting power a few hours a day. Surprisingly the plant load factor (PLF) for thermal power plant have steadily declined over the last four years and was only 63.6% in Sep. 2015. Breakthrough in solar plant technology posed a challenge for fossil fuel based thermal power plants. In April 2017, the tariff of utility connected large solar power projects in India hit a record low of Rs.3/kWh. This is the same as the average tariff of coal based power. At this tariff, solar plants are cheaper than a large number of new and old coal fired power plants in India.Stringent pollution norms add to the cost of generation of thermal power. Several projects in the power sector have become unviable on account of states like Andhra Pradesh, Uttar Pradesh and Karnataka have either cancelled the power purchase agreement or reworking on them. Few more states may follow in cancellation of power purchase agreement (PPA). Distribution Companies (DISCOMS) are reluctant to sign PPA because of high tariff, demand uncertainties, long duration of PPA and need to take the responsibility of fixed charges for the life of PPA. This will lead to creation of non-performing asset (NPA) worth Rs.1.5 lakh crores and to the extent the bank loans will be at risk.Some mitigation measures are suggested to meet the challenges in operation of coal/lignite based thermal power plants.

This report helps Nordic governments assess the EU’s proposed toolkit (Regulation 2024/1747) to support Power Purchase Agreements (PPAs) and explore ways to increase their use. PPAs are long-term contracts that make renewable energy projects bankable, easing investment and construction. The study mapped the Nordic PPA market, surveyed stakeholders, and analyzed challenges such as price transparency, counterparty risk, and regulatory uncertainty. It shows PPAs have driven renewable energy growth but identifies areas for improvement, concluding that flexible, predictable policies—rather than one-size-fits-all rules—best support market innovation.

To reach Carbon Peak in 2030 and Carbon Neutrality in 2060, China is developing renewable energy at a fast pace. Renewable energy enterprises will participate in the power market in an all-round way as China gradually improves its electricity market. Signing the Power Purchase Agreement (PPA) helps renewable energy companies to avoid market risk and achieve sustainable development. Therefore, a novel PPA pricing model is proposed in our research. Based on the theory of the Levelized Cost of Energy (LCOE), our model considers system operating costs in China’s dual-track electric power sector, which is both government-guided and market-oriented. First of all, key influencing factors of the PPA agreement are analyzed in view of the developments of the renewable energy and electricity markets in China. Next, the design of pricing strategies for renewable energy power plants to cope with market challenges is presented through a photovoltaic project case study. The results show that when the operating costs of the system are considered and other conditions remain unchanged, the investment payback period of the new energy power station will change from 10.8 years to 13.6 years. Furthermore, correlation degree and sensitivity coefficient (SAF) were introduced to conduct correlation analysis and sensitivity analysis of key elements that affect the pricing of the PPA. Finally, it is concluded that the utilization hours of power generation have the most significant effect on the PPA price, while the system’s operating cost is the least sensitive factor. The study expands the application of LCOE, and provides a decision-making solution for the PPA pricing of renewable energy power enterprises. It is expected to help promote power transactions by renewable energy companies.
