Electronic load controllers (ELCs) are a critical component of micro hydropower systems, which keep turbines, generators, and the energy they produce within safe operating ranges, as loads are switched on and off. ELCs can prevent damage to appliances and micro hydro components and even mitigate fire and electrical hazards. Despite their important role, ELCs are generally the least understood component of micro hydro systems. Equipment selection can be particularly challenging if practitioners are unfamiliar with the different types of ELCs and their relative merits.
To help demystify ELCs and ease the equipment selection process, our Controllers and Load Management Work Stream has developed an easy-to-follow factsheet. This “Basics of Electronic Load Controllers (ELCs)" tool provides a useful background on electronic, automatic and manual flow control, with pointers on their relative cost and suitability in different contexts. Specific types of ELC designs are further illuminated, as well as ballast/dump load types and control methods, commissioning checks, and useful questions to ask of suppliers.

We extend our thanks to Work Stream contributors Ajith Kumara, Bob Matthews, Dan Frydman, Jiwan Kumar Mallik and Rams Vaidhyanathan.
