“…Some papers have raised the potential of largely or entirely renewable energy supplied electricity in Japan. Tsuchiya showed that a mix of 75% solar and 25% wind would minimize required storage to balance for instability or demand‐generation timing differences, whereas the optimal supply was 50% solar, 20% wind, and 30% other renewable and back‐up power. These figures support previous studies indicating that solar‐wind power systems with appropriate back‐up and storage can provide a significant level of reliability .…”

“…The domestic CO 2 emissions in Japan have increased by 20% compared with 1990 levels in the electricity generation sector up to 2009 despite commitments to emissions reductions. Renewable energy development has been focused in Japan since tens of years ago , especially solar power and wind power , as well as biomass , and some future scenarios of renewable energy in Japan were also proposed to meet electricity demand and reduce CO 2 emission . Feed‐in tariff (FIT) policies also were focused to incent the renewable energy development ; however, the ratio of renewable energy (except hydro) in electricity supply is only less than 2% in 2010 and 20% in 2030 at maximum due to the economic, physical potential, and technological constraints .…”

SUMMARY Following on from the Fukushima Daiichi nuclear power plant accident, the Japanese government is now in the throes of reviewing its power policy. Under continuing policies of economic revival and greenhouse gas reduction, it is crucial to consider scenarios for the country to realize reliable, low‐carbon, and economic electricity systems in the future. On the other hand, the social acceptance of nuclear power will affect the final political decision significantly. Therefore, in the present study, proposed power generation scenarios in Japan in light of the Fukushima accident were reviewed comprehensively from economic, environmental, technological, resource, security, and social perspectives. The review concludes that in Japan, (i) renewable energy mainly solar and wind needs to be developed as fast as possible subject to various constraints, (ii) more gas power plants will be used to absorb the fluctuations of intermittent renewable energy and supply electricity gap, (iii) nuclear power will be reduced in the future, but a 0% nuclear power scenario by 2030 is unlikely to be a reasonable choice on most measures and (iv) the effective communication with the public is vital important.

“…In Europe, wind and solar-generated electricity roughly have negatively correlated seasonal cycles, solar generation being maximal in summer and wind generation in winter [Heide et al, 2010]. Spatial diversification is only applicable at large scale, whenever the VRE variability is sufficient (see Widén [2011] for a study focusing on Sweden and Tsuchiya [2012] analyzing Japan).…”

We develop an open-source Python software integrating flexibility needs from Variable Renewable Energies (VREs) in the development of regional energy mixes. It provides a flexible and extensible tool to researchers/engineers, and for education/outreach. It aims at evaluating and optimizing energy deployment strategies with high shares of VRE; assessing the impact of new technologies and of climate variability; conducting sensitivity studies. Specifically, to limit the algorithm's complexity, we avoid solving a full-mix cost-minimization problem by taking the mean and variance of the renewable production-demand ratio as proxies to balance services. Second, observations of VRE technologies being typically too short or nonexistent, the hourly demand and production are estimated from climate time-series and fitted to available observations. We illustrate e4clim's potential with an optimal recommissioning-study of the 2015 Italian PV-wind mix testing different climatedata sources and strategies and assessing the impact of climate variability and the robustness of the results.

“…Statistical studies that do not take into account these geographical and periodical variations, and instead rely on country-level data, are potentially flawed. Despite this obvious flaw, to the authors' knowledge little research has incorporated such variables into the analysis of future scenarios for the case of Japan [16][17][18][19], and Heard et al [20] found only 24 studies that have modelled 100% renewable systems in other countries (for example that in Lund et al [21]).…”

100% renewable energy system in Japan: Smoothening and ancillary services

et al. 2018

In the aftermath of the Paris Agreements, many countries around the globe have pledged to reduce the amount of greenhouse gas emissions being released into the atmosphere. To do so, it is important that the amount of renewable energy in the electricity grid increases, though there are worries of the capacity of the grid to cope with intermittent energy sources. To assess the feasibility of a 100% renewable energy system in Japan, the authors conducted an hourly simulation of future electricity production based on wind, solar and tidal data in Japan. The system was shown to be stable, and the authors calculated the required capacity of electrical batteries that would be necessary to balance such a system.
