[Electricity safety hazards in old top-of-line electricity meters] Private connection of electricity meters, power outage crisis and how to legally apply to Taipower to install independent electricity meters for people's livelihood

Fatal hidden dangers in attic construction: old wires and overload tripping

In Taiwan's urban disaster prevention statistics, old apartments and attic buildings (illegal construction) are dangerous areas with extremely high fire rates, and the main cause of fires, as high as 70%, is "wire fires (electrical fires)." During the construction of most rooftops, in order to avoid complicated application procedures, the water and electricity configuration is usually directly connected from the main distribution box downstairs (for example, the fourth floor apartment) through "private wiring". This means that high-power home appliances such as air conditioners, electric water heaters, and microwave ovens inside the rooftop share the same Taipower meter and power consumption quota with the residents downstairs. When high temperatures come in summer and air conditioners and electrical appliances are turned on both upstairs and downstairs at the same time, the total current can easily exceed the safe carrying capacity of wires, leading to frequent power outages and even causing aging wires in hidden pipes to become heated and embrittled, causing devastating fires.

Breaking the myth: Is it true that illegal construction cannot apply for independent electricity meters?

Many penthouse owners or tenants believe that because there is no legal title to the penthouse, Taipower will never approve the application for the installation of an independent electricity meter. In fact, based on the considerations of protecting "basic people's living needs" and "electricity safety", Taiwan Water Company and Taiwan Electric Power Company (Taipower), with the administrative cooperation of local governments, have applied for special channels to connect water and electricity to existing illegal construction:

• Taipei City Regulations: According to the "Taipei City Key Points for Applying for Water and Electricity Connection for Existing Buildings without a Use License", existing illegal buildings that existed before December 31, 1983 and were used for residential purposes, as long as they meet specific livelihood conditions, can apply to the Construction Management Office for an official document agreeing to connect water and electricity.
• New Taipei City Regulations: The New Taipei City Government also has a similar acceptance mechanism for water and electricity connections in existing buildings, mainly for those who are for residential use, have proof of residence, and have completed household registration.

[Key fact check] The electricity meter applied through this channel is only for "residential electricity use" and must not be used for business, factory or other commercial activities. If illegal use is found later, Taipower will directly cut off water and power. In addition, obtaining the official document of consent for water and electricity does not mean that the illegal building has obtained legal status. If it is inspected due to public construction or public security issues in the future, you must still cooperate with the demolition.

How to apply? The complete process of applying for the installation of Taipower independent electricity meters in illegal buildings in Shuangbei

To apply for an independent electricity meter for an old roof, the following administrative and water and electricity construction procedures must be completed in order:

1. Apply to the construction management authority for a "water and electricity connection permit": Applicants must attach documents and apply to the Construction and Management Office of Shuangbei City Government (or the Public Works Section of the District Office):
   • Application form and cut off form.
   • Certificate of house number registration (certifying that the address has a legal house number).
   • Transcript of household registration or registration certificate (to prove that someone actually lives in the space, and you cannot apply for an empty house).
   • A sketch of the building's floor plan and photos of its current condition (basic living functions such as bedrooms, bathrooms, and kitchens need to be marked).
   • Existing documents proving illegal construction (such as aerial survey maps before 1983/1998, housing tax certificates or water and electricity payment receipts).
2. Entrust qualified Grade B or above water and electricity contractors for construction: After obtaining the "official document agreeing to connect water and electricity" from the Building Management Office, you must entrust a professional water and electricity company holding a "Class A or B Electrician's License" to perform indoor circuit modifications. The plumber will re-plan the additional distribution box, install a non-fusible circuit breaker (NFB) and an earth leakage circuit breaker (ELCB), and pull the lines to the reserved position of Taipower's centralized meter box on the first floor.
3. Taipower on-site inspection and power delivery: The water and electricity contractor will submit an "internal declaration (completion inspection)" to Taipower on behalf of the homeowner. Taipower personnel will go to the site to conduct strict circuit safety inspections to confirm that the insulation resistance meets the specifications and the grounding wire is installed before power can be listed.

Purchase budget for water and electricity modification and installation agency application

In the greater Taipei area, the overall budget distribution for converting old privately connected electric wires into legal independent meter systems is as follows:

Conclusion: Safety first, asset value more secure

Although it will cost tens of thousands of yuan in initial engineering and agency fees to install an independent electricity meter on the top floor, this investment has extremely high economic and security value for the homeowner or the businessman preparing to acquire the property. An independent electric meter can not only completely eliminate the friction caused by unfair sharing of electricity bills with the neighbors downstairs, but also eliminate the major safety threat of wire fire caused by overloading of electricity. Under the premise of safe and compliant electricity use, the long-term income and transaction valuation of the property can be most securely guaranteed.

New knowledge on air conditioning power consumption and Taiwan climate maintenance regulations in recent years (2025-2026 current situation)

With the high temperatures in summer breaking historical records and the adjustment of electricity price structure in recent years, the latest statistics from the Energy Administration of the Ministry of Economic Affairs show that air-conditioning equipment accounts for more than 47% of residential electricity consumption in summer. Many people mistakenly believe that if the air conditioner is not cold, they only need to "replenish the refrigerant." However, in fact, refrigerant is not naturally consumed during normal operation in a closed circuit. If the refrigerant is insufficient, it means that there are micro leaks in the copper pipes or joints. Simply replenishing the air conditioner will only treat the symptoms but not the root cause. Refrigerant leakage will aggravate the high temperature overload of the compressor and shorten its service life.

According to Taiwan's standard operating specifications for air-conditioning projects, it is recommended that professional technicians with a refrigeration and air-conditioning decoration technician license perform "full machine high-pressure water washing and evaporator deep sterilization" every 1 to 2 years for detached air-conditioning indoor units. Especially in the humid summer in the Shuangbei Basin, the air drum and water collection tray are easy to breed black mold and jelly-like biofilm. This is also the main reason for the sour smell in the air-conditioning outlet and the backflow of the drainage pipe. Regular maintenance can maintain CSPF (Air Conditioning Seasonal Performance Factor) level one energy efficiency level, which can save an average household 15% to 20% of air conditioning electricity bills every year.

• Homeowners can do by themselves: Remove and clean the nylon filter regularly every 2 to 3 weeks (rinse with clean water and dry in a cool place, do not expose it to the sun to avoid deformation and embrittlement); clean the air outlet blades of the indoor unit with a dry cloth; check whether there is any accumulation of debris within 50 cm around the outdoor unit that hinders heat dissipation.
• Professional technicians must be entrusted according to regulations: Refrigerant pressure testing and leakage repair welding, high-pressure cleaning of indoor unit air drums and aluminum fins with liquid chemicals, reset of the drainage slope of hidden cold water pipes in the ceiling, and 220V dedicated power circuit configuration and leakage circuit breaker replacement.
