The organisation referenced in the incident description is the Indian State Load Despatch Centre (SLDC) network, which performs real‑time grid control and electricity dispatch for the national power system. SLDCs continuously monitor the voltage, frequency, and power flows on intra‑state transmission lines to ensure that the grid remains within safe operating limits. Based on these measurements, they issue operating instructions to generators, transmission licensees, and distribution companies to balance supply and demand at every moment. They also manage the scheduling of electricity purchases and sales in the wholesale market, coordinating bilateral contracts and power exchange transactions. In addition to routine dispatch, SLDCs are authorised to execute emergency control actions, such as load shedding or generation tripping, when the system faces disturbances. Their operational data are fed to the National Load Despatch Centre (NLDC) for wider‑area visibility and to support cross‑regional coordination of the Indian grid.

The specific SLDCs compromised in the 2021 incident were situated in northern India, close to the disputed Ladakh border, highlighting a geographic focus on a strategically sensitive region. As entities entrusted with the real‑time operation of the power grid, SLDCs occupy a specialised position within India’s electricity sector, distinct from planning or policy‑making bodies. Their functions are mandated by the Indian Electricity Act, 2003, and they operate under the regulatory oversight of the Ministry of Power, with technical guidance provided by the Power System Operation Corporation (POSOCO). While the source material does not disclose quantitative details such as staff strength, annual budget, or the exact number of centres, it is known that each state and union territory maintains its own SLDC. Organisationally, the SLDCs are typically embedded within the state transmission utility or the state power department, and they ultimately report to the national grid operator through the NLDC hierarchy. The distinguishing attribute of SLDCs lies in their statutory authority to issue binding dispatch instructions, a capability that confers direct operational control over electricity flows and sets them apart from advisory or consultancy organisations.
