Electricity in Mangalore is regulated through the Karnataka Power Transmission Corporation Limited (KPTCL) and distribution is through Mangalore Electricity Supply Company (MESCOM). Like many cities in India, Mangalore experiences scheduled and unscheduled power cuts, especially over the summer, to allow electricity providers to meet the consumption demands of households as well as corporations. Major industries like Mangalore Refinery and Petrochemicals (MRPL) and Mangalore Chemicals and Fertilizers (MCF) have set up their own captive power plants.

Potable water to the city is supplied by MCC. Almost all water is from the vented dam constructed across the Netravati River. The Karnataka Urban Development and Coastal Environment Management Project (KUDCEMP) aims to improve the safe water supply systems and reduce leakage and losses in the distribution system.

Both GSM and CDMA mobile services are available in the city. The main service providers are BSNL, Airtel, Vodafone, Spice Telecom, Reliance Communications and Tata Indicom. Fixed Line telecom services are offered by BSNL, Tata Indicom, Airtel and Reliance. Mangalore is the headquarters of the Dakshina Kannada Telecom District, the second largest Telecom District in Karnataka. Prominent Broadband Internet service providers in the city include Tata, Airtel and Data One by BSNL.
