Changelog

GB

We now have the EPEX Live Continuous Order Book endpoint live on our API.

USA - CAISO

We're filling our our suite of CAISO datasets. This release we have:

• Ancillary Services Prices for both the Day-Ahead Market and Real-Time Market.
• The Energy Storage Report - information about grid scale batteries and how they perform in the CAISO markets. We're really excited about this one.

USA - ERCOT

Timezones!

We've started the rollout of our timezones functionality with our ERCOT datasets. Any dataset in ERCOT with datetime values (i.e. "2024-04-18T12:36:17") has now got timezone information attached to it (i.e. "2024-04-18T12:36:17+01:00" for me in London right now).

It has a super handy functionality on the reference page with an optional dropdown menu, so you can choose what timezone to query and receive data in. If you don't select one, you will automatically receive data in UTC.

Check out an example endpoint to get started.

New geography alert!

We now have 4 CAISO datasets on the API.

These are:

• Locational Marginal Prices for each Node in the Day-Ahead Integrated Forward Market for Energy.
• Locational Marginal Prices for each Node in the Day-Ahead Integrated Forward Market for Residual Unit Commitment.
• Locational Marginal Prices in the Real-Time Market for the Real-Time Pre-Dispatch (Fifteen Minute Market, FMM).
• Locational Marginal Prices in the Real-Time Market for Real-Time Dispatch (5 minute market).

Check them out here.

Changelog

GB

We've now got live grid frequency data that we're measuring in our London office. Check it out here .

USA - ERCOT

We've now got more up-to-date Ancillary Services data for ERCOT! We now have:

• Ancillary Services Offers - DAM
• Ancillary Services Cleared Volumes - DAM

These are on a 2-day delay.

Changelog

GB

We've extended our historical data for our Elexon Insights, to ensure that we've got historical parity with our Elexon BMRS endpoints. This is so that we're ready for BMRS being commissioned during late April 2024.

Our Elexon Insights Settlement Endpoints - System Price and NIV (DISEBSP) and Detailed System Price (ISPSTACK) , which do not have historical data at source, have had their historical data mapped backwards to the start of 2020 from equivalent BMRS datasets.

Our Asset Operations and Monthly Leaderboard have both had a br column added, to reflect the new Balancing Reserve results.

Changelog

GB

Balancing Reserve

We've got new National Grid Balancing Reserve datasets live on our API. Check out:

• BR Buy Orders
• BR Sell Orders
• BR Results by Unit
• BR Results Summary

Elexon

We've separated out our Elexon section into the two Elexon data sources we pull from, BMRS and Insights. This is to prepare for the retirement of BMRS in April 2024. We will pull BMRS data until then.

USA - ERCOT

We've got two new exciting endpoints for ERCOT.

• Energy Storage Resources Operations - Live data for Energy Storage Operations as a whole in ERCOT. See how much of the fleet is charging and discharging at once, as well as the net output of the fleet.
• Settlement Point Prices - DAM - The Day-Ahead Market settlement point prices for ERCOT.

Changelog

Elexon

We've added some datasets from Elexon Insights:

• Total Load Forecast per Bidding Zone - Day-Ahead (DATL)
• Wind and Solar Generation Forecast - Day-Ahead (DGWS)
• BMU IDs and Fuel Types
• Loss of Load Probability and De-rated Margin (LOLPDRM)
• System Warnings (SYSWARN)
• Detailed System Price (ISPSTACK)
• System Price and NIV (DISEBSP)

This completes our transition from the Elexon BMRS service, which is to be decommissioned in April 2024, to the Elexon Insights service. Have a look, and let us know what else you think should be added!

Changelog

EPEX

We've completed our set of EPEX data with one final dataset:

• EPEX Intraday Reference Price EOD

This is the historical data for the EPEX intraday reference price, released by EPEX at the end of the day.

We've also added our 4 EPEX Auction endpoints (DA hourly, DA half-hourly, IDA1 and IDA2) to data downloads.

Monthly Leaderboard - column rename

We've renamed the column rated_power_mv to rated_power_mw in the Monthly Leaderboard dataset.

We've tidied up the place

We've put some of our endpoints into subfolders and given some a rename.

• Our EPEX Live endpoints are in their own subfolder within EPEX.
• To prepare for Elexon's BMRS data service being replaced by Elexon Insights, the Elexon BMRS data has been separated into its own subfolder. All the other Elexon Insights endpoints have been separated into Dynamic BM, Physical BM, Forecasts, and System as well.
• Our ERCOT datasets have been rearranged into sub-folders (DAM, RTM, SASM and System) and they have been renamed.

We made this change to make it as easy to find the data you need as possible. Any questions? Click the question mark in the bottom right to get chatting to us.

Changelog

EPEX!

We've released our brand new set of EPEX data.

M7 LIVE

We're now using live data from the EPEX M7 to produce real-time indices for the GB intraday continuous electricity market.

We are collecting improved versions of:

• EPEX Live Continuous Intraday Contract Info Report
• EPEX Live Continuous Intraday Public Trade Confirmation Report

Directly from EPEX, which are combined into:

• EPEX Live Continuous Intraday Detailed Trades

This is then used to calculate our live indices, which updates as every trade is made. This includes:

Reference Prices for each period:

• EPEX Live Continuous Intraday Reference Price
• EPEX Live Continuous Intraday Reference Price HH

Open High Low Close data for each period:

• EPEX Live Continuous Intraday OHLC

FTP formats

We've made further improvements to the format of our EPEX day-ahead and intraday auction endpoints (DA and IDA, respectively). This change affects:

• EPEX Day-Ahead Half-Hourly
• EPEX Day-Ahead Hourly
• EPEX IDA1 results (title changed from "EPEX ID D1")
• EPEX IDA2 results (title changed from "EPEX ID D")

The change consists of:

• Reformatting the data into a non-nested format, as a time series, to make it easier to use.
• Handling daylight savings hours by converting into UTC rather than local time.
• Adding unit columns.
• Making column names consistent with our N2EX endpoints so you can easily compare all wholesale data.

Check out our set of new and improved endpoints for EPEX, and let us know what you think!

Other changes

We've fixed the ERCOT RTM - Historical energy prices endpoint which now should have a full set of data.

The Generation by Fuel Type (Elexon) endpoint has been renamed from Frequency Generation type.

Changelog

We've updated our EPEX data to be more user friendly, and introduced Benchmarking Pro USA!

EPEX Updates

We've updated the formats and titles of EPEX's day-ahead and intraday auctions (DA and IDA, respectively). It's now in a simpler time-series format. The relevant datasets are:

• EPEX Day-Ahead Half-Hourly
• EPEX Day-Ahead Hourly
• EPEX IDA1 results (title changed from "EPEX ID D1")
• EPEX IDA2 results (title changed from "EPEX ID D")

The intraday auction endpoints also now have clearer descriptions, and we've cleared some bugs with our day-ahead data to ensure we get the results for the next day as quickly as possible. Check them out, and let us know what you think!
