Scenario: A 10 MW Solar Plant
- Installed capacity: 10 MW
- Annual generation: ~17,000 MWh (1,700 h/yr capacity factor)
- Linked consumption sites: 8 factories/branches monitored via Etta
- Average MCP: 2,400 TRY/MWh, peak deviation: ±40%
The Real Annual Cost of Manual Tracking
| Loss Item | Amount | Annual Cost |
|---|---|---|
| Hour-matching errors (3-5%) | ~510 MWh | 1,224,000 TRY |
| MCP/YEKDEM misapplication | ~2% drift | 816,000 TRY |
| 00:00-02:00 timezone shift (Excel) | ~120 MWh | 288,000 TRY |
| Manpower (1 full-time analyst) | — | 600,000 TRY |
| Missed consumption peaks (no Etta) | ~4% extra bill | 480,000 TRY |
| TOTAL ANNUAL LOSS | ~3,408,000 TRY |
Most of this loss is invisible — it's not money lost, it's money never earned.
Automated Management with SmartPlain + Etta
SmartPlain — Generation Side
- Automatic hourly matching of generation, MCP, YEKDEM and KBK multipliers
- Europe/Istanbul timezone standard — zero shift between 00:00-02:00
- Real-time market data via EPİAŞ integration
Etta — Consumption Side
- Hourly OSOS data from YEDAŞ / AYEDAŞ / OSMANGAZİ
- Real-time peak alerts and penalty-hour detection
- Multi-site (8 factories) management from one panel
Two-Way Balancing
Surplus hours route to consumption sites; deficit hours trigger SmartBe spot-market optimization. The consumption_site_id link binds plant ↔ factory in one click.
Annual Gains with SmartPlain + Etta
| Gain Item | Improvement | Annual Gain |
|---|---|---|
| Hour-matching accuracy | 99.7% | +1,180,000 TRY |
| Tax/YEKDEM automation | full accuracy | +800,000 TRY |
| Timezone shifts | zero | +288,000 TRY |
| Analyst workload → 1 hr/week review | — | +550,000 TRY |
| Etta peak alerts → load shifting | 4% → ~0.5% | +420,000 TRY |
| TOTAL ANNUAL GAIN | ~3,238,000 TRY |
Net ROI: After SmartPlain + Etta licensing, the investment pays back in under 2 months.
Balanced SmartPlain ↔ Etta Scenarios
Scenario 1 — Midday Generation Peak (12:00-14:00)
Plant runs at full capacity while Etta detects rising cooling load. The system suggests: "Start the 800 kW cooling unit at Factory 3 now — direct match to generation."
Scenario 2 — Evening Consumption Peak (19:00-22:00)
Generation has dropped to zero, Etta shows a sharp consumption rise. SmartBe issues a "Buy 4 MWh from spot now" signal before MCP rises further.
Who Needs This?
- Solar plant owners ≥ 5 MW
- OSB members with multiple sites
- Chains/groups managing generation and consumption separately
- Hybrid (PV + battery) operations
Conclusion
The annual gap is ~3M TRY at 10 MW, and even ~300K TRY at 1 MW. Manual tracking isn't cheap — it's just invisibly expensive. SmartPlain + Etta collapse that invisibility into one dashboard.
