“…The electric power industry is adding significant capacities of non-emitting, variable REN (renewable) energy sources, especially wind and PV (photovoltaic) solar. Those additions are helping stakeholders meet state Renewable Portfolio Standards [3] and will aid in meeting U.S. federal goals for reduced emissions.…”

“…Typical load-following flexible facilities (e.g., simple-cycle gas turbines) do not operate at full capacities because they operate to meet intermediate or peaking load [3]. On the other hand, electricity-only baseload generators 3 (e.g., nuclear power and fossil fuel-fired combined cycle power plants) often pay the grid to take electricity if they are not able to reduce power when requested by the ISO (independent system operator) due to increased deployment of REN generation and production tax credits 4 ; they result in cost and regulatory inefficiencies for many hours during the year.…”

a b s t r a c tAn RO (reverse osmosis) desalination plant is proposed as an effective, FLR (flexible load resource) to be integrated into HES (hybrid energy systems) to support various types of ancillary services to the electric grid, under variable operating conditions. To study the dynamic analysis of such system, special attention is given here to the detailed dynamic modeling and control design of RO desalination process that employs a spiral-wound membrane module. In particular, the solution-diffusion model modified with the concentration polarization theory is applied to predict RO performance over a large range of operating conditions. Simulation results involving several case studies suggest that an RO desalination plant can provide operational flexibility to participate in energy management at the utility scale by dynamically optimizing the use of excess electrical energy. The incorporation of additional commodity (fresh water) produced from a FLR allows a broader range of HES operations for maximizing overall system performance and profitability.Published by Elsevier Ltd.

“…In the past, Nuclear Power Plants (NPPs) were operated almost exclusively to cover base load demand [1] so as to maximize the efficiency and the load factor. In addition, it is often stipulated that performing load frequency regulation (i.e., adjusting the power output in response to instantaneous frequency deviations) could accelerate the NPP wear and tear [2].…”

“…The shared goal of these programs is to prepare the future nuclear cogeneration technologies and markets. On one hand, future reactors will generate higher-temperature heat, thus widening the range of market applications (Locatelli, 2013;NC2I, 2015b;Ruth et al, 2014). On the other hand, small modular reactors (SMR) are increasingly regarded by policy makers and stakeholders as a viable option to decarbonize both electricity and heat sectors (Carlsson et al, 2012).…”

Highlights: Nuclear cogeneration could support a sustainable EU energy transition. A comprehensive case study of the Loviisa 3 nuclear district heating megaproject. Obstacles arise within market, institutional and financial frameworks. Distinctive stakeholders have opposed perceptions of benefits, costs and obstacles. Greater recognition of nuclear waste heat is needed in the future EU energy policy. AbstractNuclear power plants generate electricity and a large amount of waste heat which is valuable for cogeneration. District heating (DH) is a suitable technology to decarbonize the European heat sector.By contrast with most of nuclear non-electric applications, nuclear district heating (NDH) has already been implemented in Europe, thus providing us with some valuable empirical insights. This paper investigates the forces and obstacles to nuclear cogeneration by looking at the Loviisa 3 NDH project in Finland. The key forces are energy efficiency, decarbonization of the heat sector, operational competitiveness of future nuclear technologies, and synergies with renewable energies. The key obstacles are split incentives, electricity prices volatility, inexpediency of business models and regulatory frameworks, electioneering of local authorities and pessimist expectations with regards to project financing. Policy makers should recognize nuclear plants alongside other utilities generating large amounts of wasted heat. International cooperation programs involving both nuclear and heat stakeholders should be encouraged. EU28 Member States wanting to promote nuclear cogeneration may consider providing support for the electricity generated by high-efficiency plants.
