These Terms of Service govern your use of Compounding Energy products and services. By accessing CEAtlas, CEGridSight, CompoundVision, or any related API, website, or application, you agree to be bound by these terms.
Our products and services are operated by Compounding Energy Ltd, a company registered in England and Wales under company number 17319227. Registered office: Tanners Farm, Tanners Lane, Chalkhouse Green, Reading RG4 9AB. If the operating entity ever changes, we will notify you in advance by email.
Explore-tier access is provided as-is, with no warranty of accuracy, availability, or fitness for any particular purpose. Explore-tier rate limits and feature scope may change without notice; we will provide reasonable advance notice where the change is material.
Free account. A free CEAtlas account needs an email address only; no card is taken. Its allowances (hourly 2025 capacity factors at 20 coordinates a day, the 12 × 24 profile, the annual bars, and one site analysis) belong to the account, are enforced on our servers, and are not transferable. Without an account, Explore allows one look a day at each of hourly 2025, the 12 × 24 profile and the annual bars; a site analysis needs the account. We may pause a free account that requests data in a pattern that looks automated; the map, the topology layers and the resource headline stay open, and you can write to us to have it reviewed.
Free downloads. Free-account downloads, and the day's free sample taken without an account, are licensed for your own use; do not redistribute them. An attribution to CEAtlas (Compounding Energy) is requested, and each file carries the account id (or a free-sample mark) and the time it was issued. The Acceptable Use Policy applies; the Licenses & Attribution page records the underlying data licences.
Paid plans are billed monthly or annually in advance. Annual subscriptions are billed at ten times the monthly price — equivalent to two months free. Cancellations take effect at the end of the current billing period.
Trials. Analyst and Desk plans on CEAtlas, CEGridSight and CompoundVision include a 14-day trial. A payment card is required to start a trial; you may cancel at any time during it, and if you cancel before the trial ends nothing is charged. If you do not cancel, the plan you selected is charged at the end of the trial and these terms apply to it as a paid plan.
No refunds. Fees are non-refundable once charged. We do not refund partial months, unused annual periods, or any other fees already paid, except where the law requires it.
First-quarter break clause. Annual Desk plans can be cancelled at day 90 with no further payments. You pay for the first quarter; nothing is refunded; the remaining three quarters fall away. Judge us on the public scorecard for a quarter before you commit to the year.
Enterprise subscriptions include a service-level agreement. It takes effect as a negotiated schedule to your order form, not as a unilateral promise made on this page — the commitments that bind us are the ones in the document both parties sign. What follows is the standard baseline we offer, published so you know what you are starting from before the first conversation.
Availability. We target 99.0% availability per calendar month for the API and the dashboard, measured on the component named “API” in our public status endpoint (/api/public/status), and excluding scheduled maintenance announced at least 48 hours in advance. That endpoint reports live operational state only: we do not publish an uptime history, and until we do we will not claim one. The figure reflects the architecture we actually run — a single-region deployment with a deliberately small number of moving parts, rather than a multi-region estate with automatic failover. We would rather commit to a number we can hold than quote the industry-standard figure and hope. Where an order form needs a higher target, the redundancy required to support it is scoped and priced into that agreement.
Forecast freshness. We target a new forecast vintage at least every 8 hours. Full solves run four times a day on the 00, 06, 12 and 18 UTC weather cycles, and the freshness indicator carried on every served forecast leaves green once the vintage in front of you passes 8 hours old — so this target is the same bar our own monitoring holds us to, shown to you rather than kept internal. Separately, we aim for the 06:05 UTC solve to publish by approximately 08:30–08:55 UK, ahead of the N2EX GB day-ahead auction close at 09:50 UK. That is an auction-readiness target derived from observed solve times, not a guarantee that any particular vintage lands by a particular minute.
Support. Enterprise customers receive email support during UK business hours, with a first response within one business day. Desk support is best-effort during UK business hours. Neither is a commitment to resolve an issue within a given period — a first response means a person who has read your message, not an acknowledgement from a mailbox.
Remedies. Where a service level is missed, the remedy is service credits, negotiated and recorded in your order form. We do not publish a credit formula, because the appropriate one depends on the term, the price, and what you are relying on the service to do. Service credits are the sole and exclusive remedy for a missed service level.
Accuracy is never subject to a service level. Forecasts are model output. We can commit to publishing them, on schedule and available; we cannot commit to their being right, and an agreement that said otherwise would be one we could not honestly honour. No service level, service credit, or warranty in any agreement attaches to forecast accuracy. What we offer in its place is evidence: every forecast vintage is persisted and graded against the settled market, and the results — including the periods where we forecast badly — are published on our public track record. That record, not a service credit, is how you should judge whether these forecasts are good enough for your use.
Your subscription grants your organisation a non-exclusive, non-transferable licence to use our forecasts, analytics and datasets for your own internal business purposes for the term of the subscription. That covers using the outputs in your own models, reports, and decision-making.
It does not cover redistribution. You may not resell, sublicense, republish, or otherwise make raw forecast data available to anyone outside your organisation without our written consent, as set out in the Acceptable Use Policy. Enterprise order forms can and frequently do grant redistribution and internal data-feed rights expressly; where yours does, its terms govern and prevail over this paragraph.
The restriction is not arbitrary, and it is one we are under ourselves. Much of what we publish derives from upstream sources whose licences let us use their data as a model input but restrict onward commercial redistribution of the underlying values — the position set out on our Licenses & Attribution page, which also records the sources that do permit redistribution. Rights we do not hold, we cannot grant.
You agree not to use the services to violate applicable law, infringe third-party rights, or compromise the security or availability of the platform. See the Acceptable Use Policy for specifics.
How we handle personal data is set out in our Privacy Policy. Where your use of the services involves us processing personal data on your behalf, our Data Processing Addendum forms part of these terms and records the UK GDPR Article 28 terms between us; it is the standard addendum for Desk and Enterprise subscriptions and is available to any customer, and Enterprise customers may request a countersigned copy. Most of the data in our products is market and system data rather than personal data — the addendum explains where that line falls.
All forecasts, prices, and analytics are provided for informational purposes only. They do not constitute trading, investment, engineering, planning, or operational advice. You are solely responsible for any decisions made on the basis of outputs from our services.
Everything we publish is derived from public data only — the market, system and weather sources listed on the Licenses & Attribution page, including Elexon BMRS, ENTSO-E, OMIE and NESO. Compounding Energy is not a trading firm. We do not trade electricity, gas, or related instruments, and we hold no positions in the markets we publish forecasts for.
Nothing in the services constitutes inside information within the meaning of Article 2(1) of REMIT (Regulation (EU) No 1227/2011) or Article 7 of the Market Abuse Regulation, in either their EU or retained UK form. Our outputs are the results of statistical and physical models run over information that is already in the public domain, and they are published to every subscriber on a given tier at the same time. They are not investment advice, not a recommendation or inducement to trade, and not a signal of any position we hold or intend to take. We are not authorised or regulated by the Financial Conduct Authority, and nothing in the services is a personal recommendation or advice on the merits of any transaction.
You remain solely responsible for your own regulatory compliance, including any obligations attaching to your trading under REMIT, the Market Abuse Regulation, your exchange or broker rules, and your own internal controls. If your compliance function needs a written description of our data sources and publication process, ask us and we will provide one.
To the fullest extent permitted by law, our aggregate liability arising out of or in connection with the services is limited to the fees paid by you in the 12 months preceding the claim, or USD 100, whichever is greater. We exclude liability for indirect, consequential, or special damages, including loss of profits or trading losses.
For Enterprise subscriptions the standard cap is the fees paid in the 12 months preceding the claim; the USD 100 floor exists for free and low-value accounts and has no practical application at Enterprise scale. Where a signed order form or master services agreement sets a different cap, that figure governs. Liability under these terms and under the Data Processing Addendum is subject to a single aggregate cap, not a separate cap for each.
Nothing in these terms limits or excludes liability that cannot be limited or excluded by law, including liability for death or personal injury caused by negligence, and for fraud or fraudulent misrepresentation.
Either party may terminate these terms at any time. We may suspend access immediately for breach of the Acceptable Use Policy or for non-payment.
The date at the top of this page identifies the version currently in force, and it is the version recorded against your account when you accepted these terms at sign-up. Dated copies of published versions are available on request — email privacy@compoundingenergy.com and tell us which date you need. Where an Enterprise order form incorporates a particular version by date, that version continues to govern that agreement until the parties agree a change in writing.
These terms are governed by the laws of England and Wales. Disputes are subject to the exclusive jurisdiction of the courts of England and Wales.
