Product updates and release notes for Open Electricity

Stay up to date with the latest features, improvements, and bug fixes in Open Electricity.

v4.5.2

June 3, 2026
  • API
  • Data

Data & Pipeline

  • Monthly demand accuracy - Corrected May demand and gas figures: monthly demand is now aggregated from the daily materialized view instead of a stale monthly view, with a month-aligned backfill window (#548)
  • Calendar gap-fill - Monthly and yearly series are now gap-filled onto the calendar grid, keeping market-value and weather coverage aligned (#548, #549)

Bug Fixes

  • Status grouping - Fixed secondary_grouping=status returning a 500 on /v4/data/network/; data can now be grouped by facility status (operating, committed, retired) like the other secondary groupings (#539, #550)

v4.5.1

June 1, 2026
  • API
  • Data
  • SDK
  • WEM
  • Platform

Major Features

  • Real-time WEM data - Western Australia generation and 5-minute dispatch pricing are now near-real-time via the new WEMDE dispatch-solution feed, replacing the previous ~24-hour lag (#527, #530, #533, #538)

Plans & Data Access

  • Extended historical access for Community - Community plans can now query the last 2 years of data (previously 1 year). Academic and Enterprise plans retain full history back to 1999.
  • Data licensing clarified - Plan comparisons now state usage terms: Community and Academic are licensed for non-commercial use; commercial use requires an Enterprise plan.

See Data Limits for the full breakdown.

API Improvements

  • Accurate power aggregation - Power (MW) is now averaged across intervals instead of summed, fixing inflated figures at every grouping level (#523, #525)
  • OpenAPI spec - Enriched with a generic response envelope, field metadata, and per-language code samples
  • Capacity history - Now sums capacity_maximum with a fallback to registered capacity, fixing NULL WEM coal, gas and wind capacity (#528)

Data & Pipeline

  • Gap-filled series - Chart series are reindexed onto the interval grid so upstream data gaps no longer misalign timestamps (#534, #535)

Bug Fixes

  • WEM price aggregation - Confined to WEM with a hardened parser; locf() interpolation split into separate WEM and NEM columns (#541, #542)

Notifications

  • Record debouncing - Interval milestone records are debounced to stop notification bursts, and battery-charging significance was lowered below the alert threshold to stop charging-driven alert floods

SDK Releases

Python clientopenelectricity 0.11.2

  • Proxy and custom TLS/certificate support on sync and async clients (#22, #29)
  • New renewable-with-storage and gross-demand market metrics (#31)
  • Notebook-safe sync client that works inside an existing event loop (Jupyter / IPython) (#16, #32)

  • Stronger error handling (403/404/500 surface as typed errors) (#18) and DataTable group-by and filter correctness fixes (#15, #19)

v4.5.0

April 20, 2026
  • API
  • Data
  • SDK
  • Infrastructure
  • Major Release

The 4.5.0 release moves the analytics pipeline to ClickHouse, rewrites interconnector flow tracing, and introduces a unified plan system for platform.

Major Features

  • Flow Tracing v4 - Rewritten interconnector flow solver with a dynamic, ClickHouse-backed topology model that handles circular flows and per-flow emissions, exposed through the API and the homepage (#470)
  • Automated weekly & monthly summaries - Generation and record summaries are now published automatically to X, Bluesky and LinkedIn behind a Slack approval workflow (#64)
  • Renewable-with-storage metrics - New market metrics that account for storage when computing renewable proportion

API Improvements

  • ClickHouse-backed stats - v4 station and facility stats endpoints restored and served from ClickHouse
  • Facility endpoint - Added a unit_code filter, required authentication, and corrected no-data responses to 404 (previously 416)
  • Cleaner /v4/me - Trimmed response and removed the dead with_clerk parameter from the OpenAPI spec

Data & Pipeline

  • Postgres to ClickHouse - The analytics and export pipeline (power, energy, demand, flows) was migrated to ClickHouse and the legacy Postgres aggregation pipeline retired
  • WEM demand - Derived from facility SCADA generation, since the public WEM feed provides price only
  • Crawler improvements - AEMO sources moved to polling with backoff and parallelized crawls, with gap-aware catchup that skips redundant work
  • Materialized views - Completeness-versioned daily and monthly views with full-day backfill and AEST-aligned refresh windows

Bug Fixes

  • API key authentication - New API keys no longer return 401 across all endpoints (#487)
  • Double-counting - ClickHouse FINAL scoping corrected to stop duplicate-row double-counting in market and price queries
  • Energy calculation - Corrected the trapezoidal integration window and quality-flag handling; batteries excluded from generation queries
  • Export boundaries - All series are truncated at the core generation boundary so demand, price and rooftop never extend past it
  • RecordReactor - Moved to incremental milestone detection with automatic backfill of gaps
