Special Solar Inverters to Help Reduce Power Intake

The Kerala State Electricity Board (KSEB) has invited Expression of Interest (EoI) from suppliers and manufacturers of solar inverters with ‘peak load-shifter’ facility, which enables their charging during off-peak hours.

The KSEB had earlier conducted a feasibility survey in the Cantonment Electrical Section here on the viability of using solar-powered inverters to fight rising power consumption. What the KSEB plans to do is empanel suppliers and manufacturers of off-grid solar inverters so that consumers can purchase the units from them.

The conventional inverters in fact add to the burden of the KSEB with consumers charging them during peak hours in the morning and evening when electricity consumption is at a high point.

Through the solar inverter project, the KSEB hopes to ‘postpone’ the charging of inverter batteries during the off-peak daytime hours using solar power taking the burden off the KSEB grid. “These inverters are to be charged from solar power during daytime and should be able to provide backup power to essential loads during power failure and also meet a portion of the load of the consumers during peak hours,” says the EOI document.

This April, the peak time demand has hovered between 3,100 megawatts (MW) and 3,300 MW. Peak hours are generally between 6 am and 9 am and 6 pm and 10.30 pm.
