Jaipur Vidyut Vitran Nigam Limited (JVVNL) has announced substantial revisions to its current regulations with the aim of improving the performance and efficiency of grid-connected distributed renewable energy generation systems.
The primary modification centers on the upper limit for connecting renewable energy systems to a distribution transformer. This ceiling is now established at 80 per cent of the transformer’s capacity, or as stipulated by the regulatory commission. The responsibility lies with JVVNL if a transformer upgrade is required. High-tension consumers who have personally installed transformers are not bound by the 80 per cent limitation, and their permissible solar installation capacity is determined by an alternative set of regulations. Another amendment pertains to the peak AC capacity monitoring. When a renewable energy system is set up behind the consumer’s electricity meter, the capacity of the inverter on the AC side, which is in charge of converting solar output into usable electricity, must not exceed the restrictions specified in the current regulations. A credit system will be used to make changes in the following billing cycle in cases when there is an excess of AC capacity throughout a billing cycle.
The other change pertains to net metering, a system that enables consumers to both consume energy from the grid and feed surplus energy back into it. Under these regulations, consumers are provided with guidelines for billing the energy they import from the grid, which is based on their total consumption. However, any surplus AC capacity exceeding the contracted amount will not be credited for excess generation during specific time periods. The last modification introduces a novel provision designed to waive certain surcharges for particular categories of consumers. This includes domestic users, state government buildings, local bodies, and public undertakings. The exemption applies when they utilise renewable energy systems within net metering arrangements, with the aim of encouraging the adoption of renewable energy within these groups.
