本論文は、英国の大規模再生可能電力（風力、太陽光、潮力）に対する補助金コストを、再生可能エネルギー義務契約（RO）および差額契約（CfD）制度のもとで分析する。ROは2480万kWの設備容量に対して約1030億ポンドの生涯コスト、CfDは4530万kWに対して400億ポンドのコストであり、CfDの方が消費者にとって費用対効果が高い。CfDはまた、卸売価格の高騰から消費者を保護する。将来の導入シナリオと社会経済的利益についても議論する。
English
This paper analyzes the cost of subsidizing utility-scale renewable electricity generation in the UK, covering wind, solar, and tidal stream under the Renewables Obligation (RO) and Contracts for Difference (CfD) schemes. It finds that RO supported 24.8 GW at a lifetime cost of about £103 bn, while CfD awarded 45.3 GW at £40 bn, with better value for consumers. The CfD scheme also shields billpayers from wholesale price spikes. The paper presents future deployment scenarios to 2050 and discusses socioeconomic benefits.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
英国のCfD制度は、日本でも関心が高いFIT/FIP制度と比較されることが多い。本研究は長期的な契約によるコスト安定効果を定量的に示しており、日本のエネルギー政策担当者や事業者にとって、再生可能エネルギー導入の費用対効果を考える上で示唆に富む。
In the global GX context
The UK's CfD model is a key instrument for renewable deployment globally, and this paper's cost analysis offers lessons for other countries designing subsidy schemes. It highlights the importance of long-term contracts in reducing consumer costs and decoupling electricity prices from gas.

📄 Abstract（原文）
Renewable energy technologies have historically been offered market support to facilitate their deployment and aid the transition away from fossil fuels. This work shows the costs of subsidising utility-scale renewable electricity generation in the UK, focusing on wind, solar and tidal stream technologies in the Renewables Obligation (RO) and Contracts for Difference (CfD) schemes. The subsidy of each technology is calculated using published data, including an estimate of committed costs over the full project lifetime, which is not always assessed. For the technologies considered, the RO supported 24.8 GW of installed capacity at a lifetime cost of about £103 bn. To date, CfD have been awarded for 45.3 GW of wind, solar and tidal stream, with total lifetime cost of £40 bn, although this is sensitive to future gas generation costs, with a range of £8–71 bn. The CfD scheme offers better value for money to consumers than the previous RO schemes, and this is true for all technologies assessed. By design, the CfD also helps to insulate billpayers from spikes in the wholesale market caused by high fossil fuel prices, decoupling the costs of electricity from gas. Credible scenarios for future deployment out to 2050 are also presented, along with discussion of potential socioeconomic benefits and the mechanisms to achieve these.
