DPJ
- Hydro Electric Plant with Solar-Hybrid Concept
- System Size: 10.80 kWp
- Completion: 6-Jun-2017
Project Summary
The DPJ Hydro-Electric Plant in Tabuk, Kalinga is a progressive off-grid and rural electrification strategy using a hybrid renewable model. The site draws power from a run-of-river hydro facility, taking the drop of an irrigation canal designed initially for agriculture. Solaren collaborated with the developer to launch a solar-hybrid layer, combining photovoltaic generation with hydro output to create a more balanced and reliable power profile. The challenge was twofold: to stabilize the voltage along one of their rural lines, and to maximize the generation under conditions of low flow in the dry season. Solar proved ideal. The solar system now balances demand during months of reduced hydro yield, as occurred during the sunniest months. In the meantime, hydro has a consistent baseload generation, which makes it continuous even when the sky is cloudy or at night. The result is a perfectly developed hybrid system that can provide clean energy during the day, improve the behavior of the grid in an underserved area, and establish a new standard of renewable mini-grids in the Philippines. To the local utility and to the residents, it is an efficient solution that is reliable in the long term, and it is energy powered by both water and the sun.
