EcoStart
HIGRA solution for Black Start
HIGRA EcoStart is an innovative black start solution. It allows a power plant to restart its operations without relying on external energy sources.
Using Amphibious Turbogenerators at Sanitary Flow and a Battery Energy Storage System (BESS), EcoStart generates and stores energy continuously from the minimum environmental flow. In the event of a total plant shutdown, the system releases the energy needed to drive essential auxiliary services – such as generator unit excitation, gate control and lubrication – guaranteeing the plant’s operational recovery in an autonomous, reliable and sustainable manner.
Unlike traditional methods that use diesel generators or grid power, EcoStart is completely independent, eliminating fuel costs, reducing environmental impacts and increasing the resilience of hydroelectric generation.
After fully charging the battery bank, the EcoStart solution incorporates the continuous energy generated in the sanitary flow into the plant’s main generation. This allows for an increase in installed power and guarantees greater operational efficiency for the unit.
With HIGRA EcoStart, your plant is always ready for immediate restoration, guaranteeing energy security and sustainable operation in any scenario.

BESS
HIGRA solution for Black Start
BESS (Battery Energy Storage System) is the technology that guarantees the autonomy and resilience of the HIGRA EcoStart system.
Designed to store and make energy available intelligently, it ensures the operation of the plant’s essential auxiliary services , even in the event of a totalshutdown .
With an immediate response and high efficiency, BESS provides the energy needed to drive excitation, control gates and critical systems, enabling full black start without the need for diesel generators or dependence on the electricity grid.
In addition to restoring generation, BESS helps to reduce operating costs and increase system efficiency. With robust and scalable technology, it transforms ecological flow into a reliable source of energy, promoting sustainability and operational safety.
