These Terms of Service govern use of clarkeindex.com, alpha.clarkeindex.com, and materials provided by Clarke Index, Inc. ("Clarke"). Accessing either site constitutes agreement to these Terms.
1. Use of content
All site content — including Clarke Standards, whitepaper, copy, and visual materials — is provided for informational purposes.
Permitted uses:
- Reference or quote content with attribution
- Link to publicly available pages
- Download public documents for personal or professional use
Prohibited uses:
- Republish or rehost content without attribution
- Use Clarke content to suggest partnership, endorsement, or affiliation
Facility data has its own rules, in section 2.
2. Use of Clarke data
Clarke's facility data covers the figures, buildout steps, calculations, partners and source lists on the Index, the profiles and the map, and in the CSV downloads. It is provided for your own work. These rules apply whether the data is on a public page or behind the alpha sign-in.
You may:
- use the data in your own analysis, models and decisions;
- quote individual figures in your own reports, presentations and articles, with attribution: "Source: Clarke Index (clarkeindex.com), [date]";
- download the CSV snapshot a profile offers, for your own use.
You may not, without Clarke's written permission:
- copy, scrape or download the data in bulk, or reach the site with bots, scripts or other automated tools, beyond the downloads the site offers;
- republish, redistribute, resell, sublicense or share the data, or a substantial part of it, including the CSV files, with anyone outside your organization;
- use the data to build or improve a competing dataset, product or service, or to train machine-learning models;
- share your sign-in, or let anyone else use it;
- remove or change Clarke's attribution, dates or source notes.
Clarke may suspend or end access that breaks these rules. Requests for wider use, bulk data or API access go to access@clarkeindex.com.
3. No warranties
Clarke provides facility information, Standards, capacity forecasts, and analysis "as is," without warranty of accuracy, completeness, or fitness for a particular purpose. All forecasts are inherently uncertain and should not be treated as deterministic predictions.
4. No professional advice
Clarke does not provide legal advice, investment advice, utility planning advice, or engineering or permitting guidance. All analysis is informational only.
5. Alpha access
The Clarke alpha is a pre-release product. Figures on it may be incomplete or incorrect, and they change as new filings, permits, utility records, and disclosures are added.
A sign-in for the alpha is for the person or organization it was given to. Clarke may change or withdraw alpha access at any time. Alpha access does not guarantee inclusion in paid tiers or enterprise offerings.
Applying for alpha access means you agree to be contacted by email about your application. Clarke keeps a record of sign-ins to the alpha, as described in the Privacy Policy.
6. Limitation of liability
Clarke is not liable for damages from relying on content, errors or omissions, data loss, or site interruptions. User assumes all risk.
7. Intellectual property
Clarke Index, Inc. owns all content, Standards, documents, and materials unless noted otherwise. Clarke Standards are openly reusable with attribution.
8. Changes to terms
Clarke may update Terms anytime. Continued site use indicates acceptance of updated terms.
