A monopoly, by definition, faces a downward-sloping demand curve. This allows the monopolist to restrict output and charge a higher price than would prevail in a competitive market. This leads to a deadweight loss, representing a loss of total surplus (consumer + producer surplus) to society. Consumers experience a lower quantity of electricity and a higher price, reducing their consumer surplus. The monopolist enjoys a greater profit margin, increasing their producer surplus. However, the loss in consumer surplus is likely to outweigh the gain in producer surplus, resulting in a net loss of welfare.

Consumer Welfare: Consumers are worse off due to the higher price and lower quantity. This reduces their purchasing power and access to a vital service. The deadweight loss represents the value of the consumer surplus that is not being realized.

Producer Welfare: The monopolist enjoys higher profits due to the lack of competition. This increases their producer surplus. However, the higher profits are achieved at the expense of overall societal welfare.

Government Intervention: Governments often intervene to address the negative consequences of monopolies. Possible interventions include:

• Price Controls: Setting a price ceiling below the competitive level can benefit consumers, but may lead to shortages.
• Regulation: Regulating the monopolist's output and prices can aim to mimic competitive outcomes.
• Competition Policy: Breaking up the monopoly into smaller, competing firms can increase competition and lower prices.
• Subsidies: Subsidizing the monopolist's production could lower prices for consumers.

The effectiveness of each intervention depends on the specific circumstances of the market and the goals of the government.
