Q.6. What is Market Equilibrium Conditions?
Answer
Market equilibrium conditions occur when the quantity of electricity demanded exactly equals the quantity supplied at the prevailing market-clearing price, determined graphically by the intersection of the aggregate demand and supply curves.
Market equilibrium conditions in an electricity market are satisfied at the unique price-quantity point where the aggregate demand curve (representing buyers' willingness to purchase at various prices) intersects the aggregate supply curve (representing generators' willingness to sell/marginal cost at various output levels); at this equilibrium point, the quantity of electricity demanded exactly equals the quantity supplied, and the corresponding price is the market-clearing price at which no buyer wishes to purchase more and no seller wishes to supply more at that price, representing a stable, self-sustaining market outcome absent external constraints such as transmission congestion.
