Outline of Research at the Start

固定価格買取(FIT)制度の終了を見据え,卒FITの影響や外部性(系統混雑や環境負荷増大)のフレーミング,ナッジ(気象情報に応じた消費シフトの示唆)といった介入によって,電力を生産しながら消費するプロシューマ―の行動変容がどの程度誘発されるかを経済実験により検証する.
経済実験では,プロシューマ―の利得関数をモデル化したうえで,制度変更,フレーミングおよびナッジ介入により電力消費量がどのように変化するかを計測し,計量分析する.

Outline of Final Research Achievements

To penetrate renewable energy into electricity markets, some European countries have recently introduced a feed-in premium (FIP) policy as a successor to the feed-in tariff (FIT) policy. Using laboratory experiments, this study attempts to reveal the difference in renewable energy investment between two different FIP schemes: fixed premium, which subsidizes a constant premium for any market price, and sliding premium, which ensures a certain minimum price by supplying a premium when the market price is less than the minimum price. We model an individual's decision to invest in renewable energy as a linear public goods game with uncertainty in the net return on investment: the gain from the generated electricity sold at the randomly determined market price minus the cost of investment plus the gain from the increase in the public good. We find that investments are higher under the fixed-premium scheme than under the sliding-premium scheme, but this difference decreases with repetition.

Academic Significance and Societal Importance of the Research Achievements

家庭向けの再エネ固定価格買取制度(FIT)は適用から10年を経過した世帯について順次終了(「卒FIT」という)されることになり,対象世帯数は2019年~2023年で160万件を超えたと見込まれる。また,FIT制度による賦課金は一般家庭の電気料金の約1割を占めるに至るなか,電力市場価格と連動したフィードインプレミアム制度(FIP)により家計負担を軽減する取組みも進んでいる。
卒FITが電力プロシューマ-の消費行動に与える影響やFITからFIPへの移行が再エネ投資に及ぼす影響は解明されておらず,政策検証に当たっても重要な要素であることから,本研究の成果は学術的・社会的に意義あるものと考えている。
