The Assam Electrical energy Regulatory Fee (AERC) has launched new rules in 2024 for battery vitality storage programs (BESS) within the state. These guidelines intention to information how such programs ought to be procured and managed to be used in Assam’s electrical energy community. The rules are formally often known as the Assam Electrical energy Regulatory Fee (Procurement and Dispatch of Battery Vitality Storage System) Laws, 2024. They’re issued beneath the powers given to the AERC by part 181 of the Electrical energy Act, 2003. These rules will come into drive on the date they’re revealed within the Assam Authorities Gazette and can apply all through the state.
The principle purpose of those rules is to create a correct system for the acquisition and use of vitality, capability, and ancillary providers from battery storage programs. This procurement might be finished by chosen companies, known as ‘Procurers,’ by means of aggressive bidding or by creating initiatives the place the tariff is mounted by the regulatory fee. These guidelines are solely meant for battery storage initiatives which might be related to the electrical energy grid and meet sure minimal necessities.
In keeping with the principles, every battery storage challenge will need to have an influence capability of at the very least 1 megawatt (MW). The vitality storage capability also needs to match the use case for the precise location the place the challenge is about up. Because of this the battery ought to be capable to ship electrical energy as required by that exact space. The rules are binding on a number of sorts of contributors within the electrical energy sector, reminiscent of vitality storage builders, Procurers, Middleman Procurers, Finish Procurers, Implementing Businesses, and representatives of the Procurers.
To keep away from any confusion in interpretation, the rules embrace a bit that clearly defines key phrases. As an example, the time period “Act” refers back to the Electrical energy Act of 2003, together with any amendments made to it later. The time period “Battery Vitality Storage Programs” covers programs that retailer vitality utilizing chemical processes and may later launch it as electrical energy. These programs additionally embrace any extra amenities wanted for his or her operation.
There are additionally definitions for technical and operational phrases. One such time period is “Black Begin,” which refers back to the means of a producing unit to restart with out taking electrical energy from the grid. This characteristic may be very helpful in conditions the place the electrical energy grid fails utterly. One other essential idea is the challenge growth mannequin. Phrases like “Construct-Personal-Function” (BOO) and “Construct-Personal-Function-Switch” (BOOT) are outlined to clarify other ways wherein battery storage initiatives might be deliberate and managed. Below BOO, the developer builds, owns, and operates the system for a set interval. In BOOT, the system can be transferred again to the client after that interval.
The technical facet of battery programs can be well-covered. Phrases reminiscent of “Cost Ramp Fee” and “Discharge Ramp Fee” are outlined. These charges describe how briskly a battery can start storing vitality or releasing it. These particulars are essential for correct planning and integration of battery programs into the facility grid.
Total, these new guidelines from AERC intention to help the event of battery vitality storage in Assam in a structured and clear method. By offering clear guidelines for a way storage initiatives ought to be designed, procured, and operated, the fee desires to ensure that battery programs are used successfully. It will assist enhance the reliability and adaptability of Assam’s electrical energy grid, whereas additionally supporting the expansion of renewable vitality and trendy grid applied sciences.
