Like other modern cities, Plenas enjoys a well-developed infrastructure. Several companies offer electrical, telephone, water, and sewer services, with nearly 79% of the city having a choice between more than two providers of each service. At least two companies compete for customers throughout the city and its region.

Regional transit
In addition to highways and roads, Plenas includes a variety of public transport options coordinated by the Plenas Transport Council (Consejo de Transportes de Plenas, CTP). CTP oversees and coordinates the rapid transit system, commuter rail lines, trams, and bus routes, with representatives and staff from each of the companies involved, along with city and regional government representatives as well.

Metropolitan Rapid (Rápido Metropolitano) offers, predominantly sub-surface, with three lines. The Red Line, provided by Districts Metro Transport (Tránsito Metropolitano de Barrios, TMB), runs from the southwest to the northeast. It is the longest of the lines at 52.3 km and has 28 stations, including at both Plenas Global Aerodrome terminals. Transit North of Plenas (TNP) owns and operates the Blue Line which runs northerly from central Plenas. There are 21 stations on its 34.7 km length. The third line, the Green Line, running east-west for 39.5 km with 16 stations, with Plenas Transport Company (Empressa de Transporte Plenas, ETP) as the owner-operator. Fares on Metropolitan Rapid vary based on distance traveled. CTP has developed a magnetic-stripe stored value farecard scheme, which all three Rapid lines honor, enabling riders to transfer from one line to another, paying the total fare upon completion of their journey.

Commuter railway services, under the moniker Cercanías Plenas, provide regional rail travel. The four railroad companies with routes to the city run their commuter rail operations. They coordinate schedules with CTP to facilitate transfers to different modes of transport. The companies have not adopted a uniform fare system like the Rapid farecard. Riders must, therefore, pay their fares, which vary based on trip length, on each line or mode of transport independently.

The city government operates an extensive network of tram services on several routes. The services are rather popular for their efficiency and single fare paid on boarding. A half dozen bus companies provide schedule routes, some in competition with the trams. Most routes have at least two companies providing bus service along at least portions of their distance, the major differences involving service frequency, equipment quality, pricing, and route. Some bus companies have agreed to low-cost transfer tickets which allow a rider to pay the fare on one company's bus and then buy a reduced-price transfer ticket to ride another company's bus without paying that company's full fare if boarding within the hour. While the tram and bus companies work with CTP to synchronize schedules, they have not participated in coordination of fares between providers.

Long distance travel
Railways serve Plenas with both freight and passenger services. Plenas Global Aerodrome offers domestic and international travel through any of several air transport companies. The companies own and operate the aerodrome as a consortium through the infrastructure efficiencies exception in the law that prevents monopolistic activities.
