カザフスタン、キルギス、タジキスタン、トルクメニスタン、ウズベキスタンの再エネ転換を2026年時点の最新容量データと17本の査読文献で再評価した研究。地域の再エネ容量は2023年の17.636GWから2025年に25.482GWへ44.5%増加し、純増の86.4%をウズベキスタンが占め太陽光・風力が同国ポートフォリオの75.6%に達した。容量拡大と転換の質は別物であり、系統増強・蓄電池・柔軟な運用・競争的調達・投資ルール・地域電力取引が不可欠だと論じる。MWではなく実際の発電量・信頼性・出力制限・炭素強度・統合コストで評価する「システム価値」枠組みを提案する。
English
Reassesses the green-energy transition in five Central Asian states using 2026 harmonised capacity data and 17 Scopus-indexed studies (2020-2026). Regional renewable capacity grew 44.5% from 17.636 GW (2023) to 25.482 GW (2025), with Uzbekistan contributing 86.4% of net additions and reaching 75.6% solar-wind share. The authors argue capacity growth and transition quality are distinct, and propose a system-value framework evaluating new capacity by delivered generation, reliability, curtailment, carbon intensity and integration cost rather than megawatts alone.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業にとって中央アジアは直接の開示規制対象ではないが、日系商社・重電・金融が関与する海外再エネ案件の投資判断や、移行計画における「容量だけでなくシステム価値で評価する」視点は、SSBJ・移行計画開示を検討する日本企業の海外ポートフォリオ評価に示唆を与える。
In the global GX context
Adds empirical evidence from an under-covered region to the global transition-finance and disclosure debate: it operationalises the shift from capacity-counting to system-value metrics (curtailment, integration cost, carbon intensity), which resonates with ISSB/TCFD transition-plan metrics and with development-finance and blended-finance due diligence in emerging markets.
👥 読者別の含意
🔬研究者:Provides a replicable three-indicator method (CAGR, regional contribution, technology-concentration index) for separating scale from quality in transition studies.
🏢実務担当者:Useful for firms and financiers screening Central Asian renewable projects: MW additions alone overstate transition maturity without grid, storage and procurement conditions.
🏛政策担当者:Highlights that competitive procurement, credible investment rules and regional electricity exchange are prerequisites for converting capacity growth into delivered decarbonisation.
📄 Abstract（原文）
This study reassesses the green-energy transition in Kazakhstan, the Kyrgyz Republic, Tajikistan, Turkmenistan and Uzbekistan using the latest harmonised capacity data available in 2026 and a structured review of 17 Scopus-indexed studies published in 2020-2026. The empirical design separates scale, speed and technological composition rather than treating installed renewable capacity as a single measure of transition maturity. Three indicators are calculated for 2023-2025: compound annual capacity growth, each country's contribution to regional capacity additions, and a technology-concentration index based on hydropower, solar and wind shares. Regional renewable capacity rose from 17.636 GW in 2023 to 25.482 GW in 2025, an increase of 44.5%. Uzbekistan accounted for 86.4% of the net regional addition and reached 10.027 GW, while solar and wind represented 75.6% of its renewable portfolio. Kazakhstan retained the most technologically balanced portfolio, whereas the Kyrgyz Republic and Tajikistan remained strongly hydro-dependent. The results show that capacity expansion and transition quality are analytically distinct. A durable transition requires grid reinforcement, storage, flexible dispatch, competitive procurement, credible investment rules and regional electricity exchange. The article proposes a system-value framework in which new renewable capacity is evaluated by delivered generation, reliability, curtailment, carbon intensity and integration cost rather than by megawatts alone.
