The rules and obligations governing your use of Terawatt's platform and hardware.

Last updated: 1 May 2026

Acceptance of terms

By creating a TerawattOS account, accessing the platform, ordering Terawatt Edge hardware, or clicking "I agree" during onboarding, you agree to be bound by these Terms & Conditions ("Terms") and our Privacy Policy, which is incorporated by reference.

If you do not agree to these Terms, do not use our services. Continued use of the platform after any update to these Terms constitutes acceptance of the updated version.

"Platform": means the TerawattOS software-as-a-service application, APIs, and related services.
"Edge Device": means the Terawatt Edge IoT hardware sold to Terawatt.
"Customer" or "you": means the individual or organisation that has registered for TerawattOS or purchased Edge Devices.
"Authorised User": means any employee, contractor, or agent of Customer granted access to the Platform.
"Customer Data": means all data — including telemetry data, site configurations, and reports — submitted to or generated by the Platform on Customer's behalf.

Account registration and access

1. Eligibility

You must be at least 18 years old and have authority to enter into contracts on behalf of your organisation to use TerawattOS.

2. Account credentials

You are responsible for maintaining the confidentiality of your login credentials and for all activity under your account. You must notify us immediately at security@terawattenergies.co if you suspect unauthorised access.

3. Accurate information

You agree to provide accurate, current, and complete information during registration and to keep it updated. We reserve the right to suspend accounts where information is materially false or misleading.

4. Authorised Users

You are responsible for all Authorised Users under your account. You must ensure that Authorised Users comply with these Terms and that access is promptly revoked when an individual's authorisation ends.

Subscription plans and billing

1. Plans

TerawattOS is available on the Pilot (free, 90-day trial), Growth, and Enterprise plans as described on our Pricing page. Features and limits vary by plan.

2. Payment

Subscriptions are billed in advance on a monthly or annual cycle. Payments are processed by Paystack (for Nigerian naira billing) or Stripe (for USD/GBP billing). All prices are exclusive of applicable taxes unless stated otherwise.

3. Renewals

Subscriptions renew automatically at the end of each billing cycle unless cancelled at least 7 days before renewal. Cancellation stops future charges but does not entitle you to a refund for the current billing period.

4. Late payment

Overdue invoices accrue interest at 1.5% per month. We may suspend Platform access if payment is more than 14 days overdue, after providing written notice.

5. Price changes

We will give you at least 30 days' written notice before increasing subscription prices. Price changes take effect at the next renewal after the notice period.

6. Refunds

Except where required by applicable law, subscription fees are non-refundable. If you believe you have been charged in error, contact billing@terawattenergies.co within 30 days of the charge.

Attempt to gain unauthorised access to the Platform, other customers' data, or Terawatt's infrastructure.
Scrape, reverse-engineer, decompile, or disassemble any part of the Platform.

Terawatt Edge hardware

1. Title and risk

Title to Edge Devices passes to Customer upon full payment. Risk of loss passes to Customer upon delivery to the carrier.

2. Warranty

Terawatt warrants that Edge Devices will be free from material defects in materials and workmanship for 12 months from the date of delivery ("Hardware Warranty Period"). Our sole obligation under this warranty is to repair or replace the defective device at our discretion, free of charge, within the warranty period.

The hardware warranty does not cover: damage from misuse, accident, or improper installation; normal wear and tear; damage caused by operation outside specified environmental parameters; or devices that have been modified or repaired by anyone other than Terawatt.

3. Installation

Edge Devices must be installed in accordance with the technical documentation. Terawatt is not liable for damage to inverters, equipment, or third-party systems resulting from incorrect installation.

4. Firmware updates

Terawatt may push firmware updates to Edge Devices remotely to improve performance, add features, or address security vulnerabilities. We will provide advance notice of updates that may affect device behaviour.

4. End of life

Terawatt will provide at least 24 months' notice before discontinuing firmware support for any Edge Device model.

Your data and content

You are solely responsible for the accuracy, legality, and appropriateness of Customer Data. Terawatt does not verify Customer Data and is not liable for any errors, omissions, or inaccuracies in Customer Data.

You represent and warrant that you have all necessary rights to submit Customer Data to TerawattOS, including data from OEM systems connected via integration. You are responsible for obtaining any consents required under applicable law to process data related to third parties (e.g. tenants, off-takers) within the Platform.

We recommend you maintain independent backups of critical Customer Data. Terawatt's backup and retention practices are described in our Privacy Policy.

Intellectual property

1. Terawatt IP

TerawattOS, the Terawatt Edge firmware, all associated documentation, and the Terawatt brand are owned by Terawatt Renewables Ltd or its licensors. Your subscription grants a limited, non-exclusive, non-transferable, revocable licence to use the Platform solely for your internal business purposes.

2. Customer IP

You retain all intellectual property rights in Customer Data. By using TerawattOS, you grant Terawatt a limited licence to process Customer Data solely to provide the services described in these Terms.

3. Feedback

If you provide suggestions, feedback, or ideas about the Platform or Edge Devices, you grant Terawatt a perpetual, royalty-free licence to use that feedback for any purpose, without obligation to compensate you.

4. Aggregated data

Terawatt may generate and use anonymised, aggregated data derived from Customer Data. Aggregated data does not identify you or your assets. You retain no rights in aggregated data.

Third-party integrations

TerawattOS supports integrations with third-party OEM platforms (SMA, Huawei FusionSolar, SolarEdge, and others). These integrations are provided for convenience. Terawatt does not control and is not responsible for:

The availability or accuracy of third-party OEM APIs.
Changes made by OEMs to their platforms that may affect integration functionality.
Data processed by third-party platforms under their own terms and privacy policies.

We will use reasonable efforts to maintain integrations but do not guarantee uninterrupted connectivity with third-party services. Changes to an OEM's API that break integration are not a breach of our SLA.

Uptime and service levels

For Growth and Enterprise subscribers, Terawatt targets 99.5% monthly Platform availability, excluding scheduled maintenance and events beyond our reasonable control ("Uptime SLA").

Scheduled maintenance windows will be communicated at least 48 hours in advance via email or in-platform notification. We aim to schedule maintenance during off-peak hours.

If Platform availability falls below 99.5% in any calendar month, eligible customers may request a service credit equal to 10% of that month's subscription fee per percentage point below the SLA, up to a maximum of 30% of the monthly fee. Service credits are applied against future invoices and are not redeemable for cash.

The Uptime SLA does not cover: downtime caused by Customer's actions or configurations; third-party OEM API outages; force majeure events; or beta or pilot status.

Confidentiality

Each party agrees to hold the other's confidential information in strict confidence, using at least the same degree of care it uses for its own confidential information (but no less than reasonable care), and not to disclose it to any third party except by personnel who need to know it for the purposes of these Terms.

Confidential information does not include information that: (a) is or becomes publicly available without breach of this agreement; (b) was already known to the receiving party before disclosure; (c) is independently developed without reference to the disclosing party's confidential information; or (d) is required to be disclosed by law or court order.

These confidentiality obligations survive termination of these Terms for a period of 3 years.

Warranties and disclaimers

Terawatt warrants that: (a) it has the right to provide the Platform under these Terms; (b) the Platform will perform materially as described in the documentation; and (c) it will provide the services with reasonable care and skill.

EXCEPT AS EXPRESSLY STATED IN THESE TERMS, THE PLATFORM AND EDGE DEVICES ARE PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND. To the fullest extent permitted by law, Terawatt disclaims all implied warranties, including warranties of merchantability, fitness for a particular purpose, and non-infringement.

Terawatt does not warrant that: (a) the Platform will meet all of your requirements; (b) operation will be uninterrupted or error-free; or (c) telemetry data will be 100% accurate, current, or complete. Telemetry accuracy is subject to the quality of sensor hardware, OEM APIs, and connectivity beyond Terawatt's control.

Limitation of liability

To the maximum extent permitted by applicable law:

Neither party will be liable to the other for any indirect, incidental, special, consequential, or punitive damages, including loss of revenue, profits, loss of data, loss of goodwill, arising from or related to these Terms, even if advised of the possibility of such damages.
Total aggregate liability for all claims arising out of or relating to these Terms will not exceed the total fees paid or payable by you in the 12 months immediately preceding the event giving rise to the claim.

These limitations apply regardless of the legal theory (contract, tort, strict liability, or otherwise). Some jurisdictions do not allow certain limitations of liability, in such cases, the limitation will apply to the fullest extent permitted.

Nothing in these Terms limits liability for: (a) death or personal injury caused by negligence; (b) fraud or fraudulent misrepresentation; or (c) any other liability that cannot be excluded by law.

Indemnification

You agree to defend, indemnify, and hold harmless Terawatt and its officers, directors, employees, and agents from any claims, losses, damages, liabilities, costs, and expenses (including reasonable legal fees) arising out of or related to (a) your use of the Platform or Edge Devices in violation of these Terms; (b) Customer Data; or (c) your violation of any applicable law; or (d) your infringement of any third-party right.

Term and termination

1. Term

These Terms commence when you first create an account or order a product and continue until your subscription ends or is terminated.

2. Termination by you

You may cancel your subscription at any time via account settings or by emailing billing@terawattenergies.co. Cancellation takes effect at the end of the current billing cycle.

3. Termination by Terawatt

We may suspend or terminate your account immediately on written notice if: (a) you materially breach these Terms and fail to cure within 14 days of notice; (b) you become insolvent or enter administration; (c) you misuse the Platform in a way that threatens the security of other customers; or (d) required by applicable law.

4. Effect of termination

On termination: (a) all licences granted under these Terms end; (b) you must cease using the Platform and return or destroy any confidential information; (c) you have 30 days to export Customer Data before it is deleted. Sections 7, 8, 11, 12, 13, 14, and 16 survive termination.

Governing law and disputes

These Terms are governed by the laws of the Federal Republic of Nigeria, without regard to conflict of law principles. Disputes that cannot be resolved amicably within 30 days will be referred to arbitration under the rules of the Lagos Court of Arbitration, with a seat arbitration, conducted in English, seated in Lagos.

Nothing in this section prevents either party from seeking urgent injunctive relief from a competent court.

Changes to these terms

We may update these Terms from time to time. We will provide at least 30 days' notice of material changes by email and through in-platform notification. If you continue to use TerawattOS after the effective date of the updated Terms, you accept the changes. If you do not accept the changes, you may cancel your subscription before the effective date.

General provisions

Entire agreement: These Terms, together with any applicable Order Form, constitute the entire agreement between the parties regarding the Platform and supersede all prior agreements and understandings.
Severability: If any provision is found unenforceable, the remaining provisions will continue in full force.
Waiver: Failure to enforce any provision does not constitute a waiver of the right to enforce it in the future.
Assignment: You may not assign these Terms without Terawatt's prior written consent. Terawatt may assign these Terms in connection with a merger, acquisition, or sale of assets.
Force majeure: Neither party is liable for delays or failures caused by events beyond reasonable control, including natural disasters, government actions, or internet infrastructure failures.
No partnership: These Terms do not create a partnership, joint venture, employment, or agency relationship between the parties.
Notices: Legal notices must be sent by email with read receipt to legal@terawattenergies.co or to registered post to our Lagos address.
