Micro grids are having a big impact on remote areas of the world. Romina Arcamone Garcia, Market Manager, Renewable Energy & Backup Power at Trojan Battery Co., LLC explains to PES how 24/7 energy is now possible in these areas.
The establishment of off-grid networks, also known as mini grids or micro grids, around the world is increasing as a way to supply power to remote towns, villages and areas that are not connected to the main electric grid, or only have access to electricity a few hours a day.
Battery-based microgrid systems ensure that these areas have access to energy 24/7, enabling remote communities to operate lighting, communications, radios, TV and other electrical equipment. Access to these types of devices, play a vital role in enhancing productivity of local businesses and foster the development of commercial activities in developing regions of the world.
In addition, battery-based installations reduce operating costs which diesel-powered installations face such as the rising costs of fuel consumption, fuel transportation, and maintenance of diesel generators.
Off-grid photovoltaic (PV) networks have unique power storage requirements due to the varying levels of irradiance, temperature and sun hours available at a particular location. Deep-cycle batteries are key components in PV applications to provide reliable energy storage, by improving the overall performance of microgrids.
Microgrid systems require highly reliable batteries that can last 15 to 20 years in the application without the need of replacement. One key aspect to consider when installing a microgrid is that the communities are located in very remote areas, this means that the components have to be carried by boats or people to their final destination. Transportation is not a minor aspect to consider, access to lifting machines is very rare, so batteries with rugged cases are the best option. Selecting the right battery technology and type play an important part in implementing a successful project.
