Overview

Our grid is transforming. A commercial and industrial (C&I) customer can also be an electricity producer as well as a consumer (i.e., a prosumer). Therefore, a battery energy storage system is becoming integral to the changing relationship between utilities and their customers. PQpluS enables its users to reduce energy costs and makes the network more resilient while improving the power system's efficiency, reliability, and availability. It helps the electricity consumer by actively managing the timing and profile of their energy usage through the following functions:

Peak shaving
The energy consumption pattern in the C&I segment follows a cycle of peak and low load conditions. Peak load periods coinciding for several consumers can lead to a shortage of power supply. To avoid such situation, utilities often charge premium prices for energy consumed during peak hours, resulting in high energy costs to the consumer. PQpluS is used for peak demand shaving, resulting in a uniform load distribution around the complete load cycle and saving penalties for the consumer.

Easier use of self-generation and time-of-use tariffs

PQpluS units offer multiple ways for consumers to reduce their electricity bills without requiring changes in consumption habits. In regions with dynamic time-of-use pricing, they can charge their batteries either from their rooftop solar PV system or from the grid during off-peak hours and then discharge as needed during peak hours, thereby obtaining the cost savings of demand shifting without actually changing the times when they use energy.

Facilitating connection of renewable resources

Limited predictability is a critical drawback of green energy sources such as wind and solar plants. Due to its unpredictable behaviour, a significant renewable energy source imposes an additional burden on the network operators. The PQpluS units can minimize the impact of renewables on the network by offering a “buffer” that can absorb excess power and release it when the output from these sources falls short.

Integration of fast EV chargers

PQpluS units accompany fast EV chargers in remote places along highways where grid operators cannot offer enough power connection for ultra-fast or fast charging service. With PQpluS, you can avoid or postpone grid investment while still using high-power chargers.
