SolarNest by TCSASSB Powers Coara Marang’s 100MW Solar Plant with a Unified Web Portal Solution

At the heart of Terengganu, the Coara Marang 100MW Solar Plant stands as a beacon of clean energy—powering over 55,000 Malaysian homes with renewable electricity. Behind the scenes of this large-scale solar operation, TCSASSB has delivered a game-changing digital backbone in the form of SolarNest, a fully integrated web portal system tailored for solar plant operations, monitoring, and billing.

A Smart Platform, Built for Solar

Designed, developed, and validated with the approval of Fichtner, the Coara Marang web portal. Now officially branded as SolarNest, goes far beyond standard SCADA dashboards. It brings together multiple critical systems into one intelligent platform:
Billing Automation
The system connects directly to the ITRON energy meter, capturing monthly energy generation data and automatically converting it into a PDF billing statement ready for submission to the Single Buyer. No more manual data collection, no more spreadsheets, just fast, accurate, and effortless billing.
Real-Time Plant Monitoring
Through seamless integration with TNB GSO Web Services and weather forecast data, SolarNest offers dynamic visibility into plant performance, environmental impacts, and energy forecasts.
O&M Dashboard and Alarms
All real-time data, alarms, and key operational information are instantly accessible to both the O&M team and the plant owners, enabling better coordination and faster response times.

Solar Plant ?

The Power of One: Replacing Fragmented Systems with SolarNest

Many solar farms face disruptions due to fragmented systems—separate billing, SCADA, weather, and alarms. SolarNest unifies them all, streamlining operations under one platform. The result ?

A System That Understands Solar

What sets TCSASSB apart is not just technical expertise—but deep domain knowledge in renewable energy. Our team understands the workflow, compliance needs, and operational challenges of solar plants, and we’ve engineered SolarNest to meet them head-on. From energy data to regulatory reporting, from weather forecasts to real-time alarms—SolarNest speaks the language of solar.

Helping Owners and O&M Teams Stay Ahead

For solar plant owners, SolarNest offers full transparency over their investment. Performance tracking, generation reports, billing summaries, and alarm histories are just a few clicks away—anytime, anywhere.
For the O&M teams, SolarNest acts as a digital logbook and control center. It documents every action, event, and alarm across the plant, creating a clear history of operational performance and maintenance activity. This improves accountability, simplifies audits, and enables data-driven optimization of the plant’s efficiency.

After the success at Coara Marang, SolarNest is now ready to power the future of other solar projects across Malaysia and beyond. Whether you’re operating a 5MW site or a 500MW solar park, SolarNest is scalable, adaptable, and built with your needs in mind.
