Meralco's business is divided into two segments: power and other services.
The power segment of Meralco's business consists of electricity distribution (through Meralco and its subsidiary, Clark Electric Distribution Corporation), power generation (through its wholly-owned subsidiary, Meralco PowerGen Corporation) and retail electricity supply (through a business unit, MPower).
The other services segment is involved principally in electricity-related services such as electro-mechanical engineering, construction, consulting and related manpower, light rail maintenance, bills payment collection and e-transaction, insurance and energy efficiency and systems management.
