DPJ
- Hydro Electric Plant with Solar-Hybrid Concept
- System Size: 10.80 kWp
- Completion: 6-Jun-2017
Project Summary
Most renewable energy installations solve one problem. The DPJ project in Tabuk, Kalinga, solves two simultaneously, and each solution makes the other more effective.
The site draws power from a run-of-river hydro facility using the drop of an irrigation canal originally built for agriculture. Hydro provides consistent baseload generation around the clock, including nights and cloudy days. But during the dry season, reduced water flow cuts hydro output precisely when solar irradiance is at its peak. Solar fills that gap exactly.
The inverse is equally true. During wet season months when hydro runs strongly, solar provides supplementary generation during daylight hours without competing with the baseload. The two sources complement each other across the full annual cycle in a way that neither could achieve alone.
Solaren’s role was to engineer the solar layer into an existing hydro system, stabilising voltage along rural distribution lines and maximising total generation across seasonal variation. The result is a clean energy mini-grid serving an underserved community in Kalinga with a reliability profile that conventional single-source systems cannot match.
For remote electrification projects where grid connection is impractical, customised energy solutions built around the specific resources available on site deliver outcomes that no standard specification can replicate.
