Solar PV Integration
Cleori enables solar photovoltaic systems to participate in the Estonian mFRR (manual Frequency Restoration Reserve) market operated by Elering. Our platform provides seamless integration for commercial and utility-scale solar systems, unlocking new revenue streams through grid flexibility services.
Why Solar Flexibility?
Solar PV systems are ideal for flexibility markets due to their:
- Down-regulation capability - Reduce output during grid oversupply
- Fast response times - Activation within minutes
- Revenue generation - Compensation for flexibility services
- Grid support - Help balance renewable energy on the grid
Integration Requirements
Minimum Specifications
- Capacity: 100 kW minimum installed
- Inverter: Remote control capability
- Response: < 15 minutes activation
- Granularity: 5% power steps
Supported Technologies
- String inverters with curtailment
- Central inverters
- Power optimizers with control
- Smart inverters (grid-following)
- All major inverter brands
Telemetry Requirements
Important: Telemetry must be sent at least every 10 seconds to meet Estonian mFRR market requirements.
| Parameter | Field | Unit | Description | Required |
|---|---|---|---|---|
| Time | time | RFC 3339 | Timestamp of measurement | ✅ |
| Power | power | kW | Current generation (always positive) | ✅ |
Flexible Submission: Telemetry values can be sent all together in a single request or individually as they become available. The API accepts partial updates - you only need to include the time field and at least one measurement value.
Integration via Cleori API
Currently, integration is supported exclusively through the Cleori API. Partners must implement the required endpoints for telemetry submission and curtailment activation reception.
Sending Telemetry
Receiving and Confirming Activations
Time-Critical: Activation signals must be acknowledged promptly to maintain grid stability during overproduction events.
Polling Requirement: Activations must be checked at least once per minute to ensure timely response to grid requirements.
