In order to encourage the development of renewable energy in the private sector, under the Feed-in Tariff Scheme, electricity generated by renewable energy systems (such as solar power systems) can be sold to power companies at a price higher than the normal tariff level, thereby Helping the private sector recover the cost of investment in renewable energy systems and power generation. In order to provide sufficient incentives to encourage potential renewable energy developers, the Feed-in Tariff Scheme adopts a "total feed-in tariff", that is, a feed-in tariff can be obtained for each kilowatt-hour of electricity generated by the renewable energy system. As for the electricity used on the premises, the electricity company will charge electricity charges according to the prevailing electricity tariff.

Currently, feed-in tariffs will be available for solar and wind power systems.

All customers of power companies, except government agencies, who plan to install a distributed renewable energy system with a generating capacity of not more than one megawatt on their premises and connect them to the power company grid supplying the area, i.e. Eligible to apply to the power company, according to the electricity generated by the system, according to the specified price to charge the electricity price. Renewable energy systems with generating capacity exceeding one megawatt will be considered on a case-by-case basis.

The distributed renewable energy system that you can install before the implementation of the Feed-in Tariff Scheme can participate in the Feed-in Tariff Scheme and receive 2 feed-in tariffs.

For arrangements to apply to the power company to participate in the Feed-in Tariff Scheme, please refer to the following website of the power company: For arrangements of the Hong Kong and China Electric Power Company Limited (CLP), please refer to the following website: https://www.clp. com.hk/en/community-andenvironment/renewable-schemes/feed-in-tariff For arrangements of The Hong Kong Electric Company Limited (HK Electric), please refer to the following website: https://www.hkelectric. com/en/customer-services/smart-powerservices/feed-in-tariff-scheme Generally, applicants are required to: (a) is a customer of the relevant power company; (b) Submit a copy of ID card (individual) or business registration certificate (institutional) to the power company; (c) submit design, specifications, operating procedures, testing, and cost information for the renewable energy system to the utility; and (d) Confirm that you understand the ordinances, statutory regulations and licensing requirements of the relevant works.

While implementing the Feed-in Tariff Scheme, power companies must also take into account the maintenance of a safe and reliable electricity supply. Generally speaking, the power company needs to discuss with the customer about the generation capacity of the individual application in the following situations: (a) The application system is located in a location outside the coverage of the existing grid (eg, wasteland). The laying of the grid may require traversing undeveloped land and roads, and the works involved and the application 3 required are complex and time-consuming. In addition, adding a power grid involves a relatively large investment and must also take into account the maintenance of a safe and reliable power supply; (b) Only basic power supply facilities (such as power supply overhead lines) are provided at the location of the application system, and the relevant power supply capacity cannot support the power capacity of the application system. The power grid upgrading works may also be limited by the geographical environment (if the location where the cable needs to be laid is located on private land, the consent of the relevant land owner is required; if the location where the cable needs to be laid is already covered with facilities of other public utilities, there may not be any enough space for higher capacity cables, etc.); and (c) Connecting a renewable energy system with a larger generating capacity to the grid, or densely connecting many smaller renewable energy systems to the grid in the same area, will increase the voltage even beyond the The voltage that can be loaded by the existing power supply equipment in the same area may cause voltage instability and ultimately affect the power supply stability of other customers in the same area.

The power company will not charge any application fee and grid connection fee unless the power company needs to make changes, additions, enhancements or upgrades to the grid connection application.

The capital cost of a renewable energy system will vary depending on the power generation capacity of the system, renewable energy technology, etc. Generally speaking, the capital investment of a solar power generation system is about tens of thousands of yuan per kilowatt, including the cost of wages and inspections, structural support components, inverters and photovoltaic modules.

Dust or dirt on the surface of the solar panel will reduce the power generation. It is recommended that the owner of the renewable energy system perform simple cleaning work on a regular basis. The inspection, maintenance and repair of the electrical installations of the solar power system must be carried out by registered electrical contractors.

The lifetime of a solar panel is about 20 to 30 years, and the lifetime of an inverter is about 5 to 10 years.

We suggest that members of the public can request suppliers or contractors to include at least 1-year fault repair liability period in the contract terms of solar power system works. After the first fault repair liability period, members of the public can decide to continue to entrust the original contractor or hire a new contractor to provide the service.

Renewable energy system owners can receive feed-in tariff payments at the feed-in tariff price at the time of participating in the scheme from the time their systems are put into operation and participate in the Feed-in Tariff Scheme, until December 31, 2033 (i.e. the government and the two the expiry date of the new Scheme of Control Agreement signed by the power companies respectively), or until the end of the life of the system, whichever is earlier. In other words, the renewable energy system owner can receive a feed-in tariff for a maximum of about 15 years (for CLP, a maximum of 15 years and 3 months; for HK Electric, 15 years).

2021 feed-in tariffs are: (a) Renewable energy system generating capacity equal to or less than 10 kW: 5yuan; (b) Renewable energy system generating capacity exceeding 10 kW but not exceeding200 kW: $4; and (c) Renewable energy system generating capacity exceeding 200 kW but not exceeding 1MW: 3 yuan. Fit-in tariff rates are reviewed annually,

The government commissioned an independent consultant to conduct a study on the determination of the feed-in tariff. In determining the feed-in tariff price, the consultant made reference to the mechanisms and criteria adopted by the feed-in tariff schemes around the world, and took into account the average electricity generation cost of the renewable energy system in Hong Kong. When calculating the average cost of electricity generation for a renewable energy system, we are based on reducing the payback period of the system to about 10 years. In addition to considering the construction cost of installing a renewable energy system, we also considered maintenance expenses, discount rates, inflation factors and the attractiveness of pricing for investment in renewable energy systems.

The construction cost of a renewable energy system, as well as the cost of generating electricity, will vary depending on the systemThe power generation capacity of the system varies. Generally speaking, the renewable energyThe larger the power generation capacity of the system, the cheaper the average construction cost per kilowatt.The average cost of electricity generation is also lower. Set different levels of on-grid electricity prices,Reasons for generating capacity and average cost of generating electricity can be more effectively and equitably reflectedwhite. In other regions, feed-in tariffs are responsive to the development of renewable energy systemsIt is very common to have different levels of capacitance. in German, EnglishTake China, Japan and Taiwan as examples, their feed-in tariffs also range from 2 to 4different levels. In considering the renewable energy systems most likely to be installed in the Hong Kong environmentAfter generating capacity, we believe that there should be different levels of feed-in tariffsPrice, covering different systems: minimum level (for generating capacity 10kW or less) covers most systems on the roofs of village houses;Level 2 (applicable to generating capacity exceeding 10 kW but not exceeding 200kilowatt-based systems) covers systems on the roof of general buildings (such as airport policeDepartment and Wanchai Government Building); third level (applicable to generating capacitysystems exceeding 200 kW but not more than 1 000 kW) cover relativeLarger systems (eg those at EMSD headquarters).

Once the renewable energy system owner's application for feed-in tariff is approved, and the system is put into operation within a reasonable time, the system can obtain the feed-in tariff from the time of commissioning until December 2033 according to the feed-in tariff price when participating in the "feed-in tariff plan". 31st March, or until the end of the life of the system, whichever is earlier.

After the renewable energy system is successfully connected to the power grid and the smart meter is installed, the relevant power company will calculate the feed-in tariff payment that can be obtained by the system based on the system output recorded by the smart meter, and issue it to the relevant customers on a regular basis.

The power company will calculate the feed-in tariff payment that can be obtained by the renewable energy system based on the total electricity production recorded by the smart meter, and disburse it to the relevant electricity account holders who have been approved to participate in the Feed-in Tariff Scheme.

The Government has noticed that there are companies in the market that provide individuals or organizations with different investment models for installing solar power systems, including the solar system leasing model. The owners of the premises share the income from participating in the "On-grid Grid Scheme". Individuals or institutions interested in installing renewable energy systems on their premises may consider different modes of participating in the Feed-in Tariff Scheme according to their own circumstances.

About the technical matters of grid connection and the procedures for applying to the power company for grid connection, you can download the "Technical Guidelines for Renewable Energy Power Generation System and Grid Connection (2016 Edition)" from the following webpage for reference: https://www.emsd.gov.hk/filemanager/ en/content_299/TG_Grid_Connection_Renewable_Energy_Power_Systems.pdf

Power companies have agreed to waive the connection fees for connecting small-scale renewable energy systems to the grid. CLP will accept applications for the Feed-in Tariff Scheme from May 4, 2018. For details, please refer to: https://www. clp.com.hk/en/community-and-environment/renewable-schemes/feed-in-tariff HK Electric will accept applications for the Feed-in Tariff Scheme from 28 August 2018. For details, please refer to: https://www.hkelectric. com/en/customer-services/smartpower-services/feed-in-tariff-scheme

If the owner of a renewable energy power generation system intends to connect the system to the grid, it is required to register its power generation facility with the EMSD under the Electricity Ordinance (Cap. 406). Therefore, members of the public who wish to participate in the Feed-in Tariff Scheme for the renewable energy systems in their ordinary homes are required to register the systems with the EMSD. The registration fee is $640. The registration form and details are available on the EMSD website (https://www.emsd.gov.hk/en/electricity_safety/how_to_apply/registration_for_generating_facility/index.html). If the installation is part of an electrical installation subject to a periodic test certificate, the registration fee is waived. According to the Electricity Ordinance, electrical installations in hospitals, schools, etc. are electrical installations subject to periodic test certificates and are therefore exempt from registration fees. For enquiries, please call the EMSD hotline: 6395 2930.

If the solar power generation system is of the same scale as the permitted use/installation in the same zone of the statutory plan, and is incidental to, directly related to and ancillary to the use/installation, planning permission from the Town Planning Board is not required for the installation. As for the stand-alone solar power generation system installed on vacant land participating in the Feed-in Tariff Scheme, it is regarded as a "public utility installation" and is subject to the requirements of the relevant statutory plans and may require planning permission from the Town Planning Board . The proponent may refer to the relevant Outline Zoning Plan and its annotations to understand the land use zone where the site is located. "Utility installations" are either frequently permitted uses or uses that require the permission of the Town Planning Board. If planning permission from the Town Planning Board is required, the proponent may submit a planning application to the Town Planning Board under the Town Planning Ordinance (Cap. 131). The application form and application instructions can be found on the Town Planning Board website (https://www.info.gov.hk/tpb) to download. The judging criteria for solar power system planning applications can be found at: https://www.info.gov.hk/tpb/tc/forms/Technical_Doc/Assessment%20Criteria_promulgation%20(Chinese)%20(21.7.2020).pdf

Renewable energy certificates are sold by power companies, and each kilowatt-hour of electricity on the certificate indicates the unit of electricity produced or purchased by the power company from local renewable energy.

The sale of renewable energy certificates helps raise public awareness of environmental protection. The community can support the development of renewable energy by purchasing these renewable energy certificates; and the revenue from the sale of renewable energy certificates will also help mitigate the impact of the implementation of the Feed-in Tariff Scheme on electricity bills for all users.

Renewable energy certificates are priced at HK$5 per kWh.

The Renewable Energy Certificate Scheme is voluntary.

Any residential or commercial customer can purchase a renewable energy certificate from the power company in their area.

The minimum purchase quantity for a Renewable Energy Certificate is 100 kWh.

Installing a solar power generation system in accordance with legal requirements will not cause unauthorized construction problems. If you intend to install solar power systems in New Territories exempted houses (commonly known as village houses), please refer to Questions 5.2-5.7. If you plan to install a solar power system on vacant land, please refer to Questions 5.8-5.10. See Questions 5.11-5.13 if you plan to install a solar power system in a private building. If you plan to install a solar power system in a squatter house, please refer to Question 5.14. If you plan to install a solar power system on farmland or fish ponds, see Question 5.15.

According to the Lands Department and the Buildings Department's New Territories Exempted House Small Environmental Protection and Amenity Facility Policy, subject to certain requirements, tenants may use the roofs and stairs of village houses without prior approval from the Lands Department or the Buildings Department. The stairhood is installed with a solar power generation system. If the garden adjacent to the village house is privately owned or is located on short-term tenancy land and complies with the land use and the terms of the lease or tenancy agreement, the relevant landlord or tenant may follow the simplified requirements of the Buildings Department's "Minor Works Control System" i.e. Minor Works Item 1.50(https://www.bd.gov.hk/en/building-works/minorworks/minor-works-items/index_mwcs_item1_50.html) or Item 3.50(https://www.bd.gov.hk/tc/buildingworks/minor-works/minor-works-items/index_mwcs_item3_50.html) For the installation of solar power generation systems, the relevant works shall be undertaken by competent persons to ensure that the relevant minor works comply with the requirements of the Buildings Ordinance (Cap. 123). If the construction works involved are not exempted construction works or minor works items, the relevant landlord or tenant should engage an authorised person to submit the building plans to the Buildings Department in accordance with the provisions of the Buildings Ordinance, and after obtaining approval and consent to commence the works to proceed.

The coverage of the solar power generation system on the roof refers to theThe total coverage area of all parts of the system (including solar panels, brackets and solar panels)spaces or gaps between solar panels, etc.). such as solar power systemsretractable movable members, then their total coverage when fully extendedcumulative calculation. As for the continuous covering mounted on the retractable movable memberSolar power generation system, when the component is fully opened, the coverage is as high asmore than half of the covered area of the relevant New Territories exempted houseThe relevant provisions will be regarded as unauthorised structures. Owners must also take care and ensure thatThe structure of these retractable members and the safety of electrical installations.

No. The space below the solar power system must not be enclosed in any form or to any degree. If the space under the solar panel is wholly or partially enclosed by tents, fixed or movable components constructed of metal or glass, prefabricated lockers (whether or not they are small environmentally friendly and comfortable facilities), or solar panels and their ancillary components, etc., will be considered non-compliance with the relevant regulations. When designing and arranging solar panels, avoid creating any degree of enclosed space.

No. Before installing the solar power generation system, the owners of the village houses are required to remove the existing UBWs on the roof according to the relevant regulations, including the UBW declaration scheme implemented by the Buildings Department for UBWs in New Territories exempted buildings. Confirmed UBWs must also be demolished. Therefore, 14 a solar power generation system installed on an unauthorized structure on the roof will also be regarded as an unauthorized structure. The BD will take enforcement actions in accordance with the enhanced enforcement strategy for UBWs in New Territories Exempted Buildings.

Generally speaking, if the solar power generation system installed on the roof of a village house is mainlyAncillary facilities that assist in supplying electricity to households will not violate relevant regulationsplanned use.
