| SCADA and remote monitoring/control | AVEVA Wonderware (System Platform / InTouch), Siemens WinCC (PCS 7), Schneider EcoStruxure, Rockwell FactoryTalk, ABB; local integrators (Bautek, SGE) | Monitors inverters, transformers and switchgear 24/7 at large plants, and handles curtailment and TEİAŞ data exchange; but licences are expensive, deployment is heavy and it is mostly single-site. It does not show a multi-site portfolio together with financial and market data on one management screen. |
| Inverter manufacturers' monitoring clouds | Huawei FusionSolar, SMA Sunny Portal / ennexOS, SolarEdge Monitoring, Fronius Solar.web, Solis SolarCloud, Sungrow iSolarCloud | Provides per-brand production, string performance and fault tracking for rooftop and ground-mount solar; FusionSolar is very widespread in Türkiye. But it is brand-locked (vendor lock-in): sites with different brands cannot be combined on one dashboard, and the public APIs are underused for a single normalised view. |
| Solar/wind design, simulation and proposals | PVsyst (P50/P90 bank reports), Valentin PV*SOL, Aurora Solar / HelioScope, SurgePV; WindPRO / WAsP for wind | Lets the EPC firm prepare feasibility studies, yield estimates, performance ratios and bank reports; a pre-project tool. It does not cover actual production, performance tracking or maintenance operations after the plant is commissioned. |
| OSOS, metering and EMS / energy monitoring | Netaş NEOS OSOS, METRUM, Bimetri, İlkem; on the EMS side DEOS DATA, CTS, Reengen, CARBIOT, Schneider Power Monitoring Expert | Covers remote meter reading, reactive/compensation tracking and in-plant consumption monitoring; fundamental for an ISO 50001 baseline. But OSOS data often stays with the distribution company, and the EMS never joins production and market data on the same dashboard. |
| EPİAŞ market, ETRM and production forecasting | EPİAŞ Market Management System (PYS), Transparency Platform (seffaflik.epias.com.tr), YEKDEM; on the ETRM side APLUS Enerji RIX ETRM, Gain Enerji portfolio | Manages the day-ahead market, balancing-settlement and YEKDEM financial processes. Professional ETRM solutions are positioned and priced for large portfolios; at SME scale, day-ahead bids and imbalance cost are still largely calculated by hand. |
| Maintenance (CMMS), projects and ERP | CMMS: Bakım724, Servix, PBT PRO, Repairist, SAP PM/EAM, IBM Maximo; projects: Oracle Primavera P6, MS Project; ERP: Logo (Tiger/Netsis), Mikro, SAP | Covers maintenance, EPC project planning and the finance-stock-purchasing side. But plant production, SCADA/OSOS measurements, EPİAŞ settlement and field maintenance sit outside these systems, mostly in Excel and brand portals; this is the clearest integration gap. |
