1. Official Provincial Disclosure Platforms (Free)
These are the primary/authoritative sources. Data is published by each province's power trading center (电力交易中心) or the market information disclosure platform run by the grid dispatch center. State Grid provinces typically use the "新一代电力交易平台" portal pattern https://pmos.<province-code>.sgcc.com.cn.

Caveats: Chinese-language only; some portals require mainland IP or browser certificate exceptions; public pages usually show only recent days (long histories require member export or daily scraping); URLs change occasionally — verify before relying on them.

3. Financial / Research Data Terminals
| Provider | URL | Data Available | Granularity | Price |
|---|---|---|---|---|
| Wind 万得 | https://www.wind.com.cn |
Selected provincial spot price series, coal & power indices | Daily/monthly | Institutional terminal subscription (tens of thousands RMB/yr) |
| iFinD 同花顺 | https://www.51ifind.com |
Similar power-market series | Daily/monthly | Institutional subscription (cheaper than Wind) |
| CEIC | https://www.ceicdata.com |
China electricity price indicators (e.g., 36-city retail prices) — regulated tariffs more than spot | Monthly | Institutional subscription |
| EPS Data | https://olap.epsnet.com.cn |
China energy statistics databases | Monthly/annual | Institutional subscription |
These terminals are best for averages and cross-checking; they generally do not carry full 15-minute nodal spot curves.
4. Practical Recommendations
- Need full 96-point historical curves (research / trading models): subscribe to 电查查 or a similar vendor, or partner with a registered market participant (售电公司 / generator) who can export archives from the official trading platform.
- Need weekly or monthly averages (policy analysis, reporting): free BJX weekly reports + 泛能网 monthly summaries are sufficient and can be compiled manually.
- Building an ongoing dataset: set up a daily scraper against provincial disclosure pages going forward; historical backfill on public pages is limited, so start early.
- Academic use: check published papers (e.g., Guangdong pilot studies) and think-tank reports (RMI China power market reviews) for cleaned datasets or replication files; some researchers share scraped data on GitHub.
Disclaimer: platform coverage, URLs, and access policies change frequently in China's rapidly evolving market — verify current terms with each provider before purchasing.
