OverviewBusinessesIndividualsRECsCarbon CreditsSustainability ConsultingThe OneMillionTrees MovementContact Us Renewable Energy Certificates Renewable Energy Certificate (REC) is a type of Energy Attribute Certificate (EAC) that represents the environmental attributes of the generation of a one-megawatt hour (MWh) of energy produced by renewable sources. RECs can originate from wind, solar, biomass, hydropower, biogas, geothermal, and landfill gas projects. They can be used to validate the consumption of electricity from renewable sources to offset electricity consumption from non-renewable sources. Benefits of RECs: Traceable – each REC comes with a unique serial number that can be used to verify claims and ensure that it is only sold and redeemed once. Supports the renewable energy market by signaling demand for the generation of more renewable energy Encourages the generation of clean energy that produces no greenhouse gas emissions from fossil fuels. How we can assist you Making creditable claims SP Group is an accredited partner of I-REC Standard, an international recognised registry to provide RECs that are traceable to the source of generation.

SATURDAY, NOVEMBER 23, 2013 Careers in Engineering Packing a lot of power Principal engineer Chan Hong Jiang relishes the unpredictable challenges that he faces in his job at Singapore Power by suresh nair PRINCIPAL engineer Chan Hong Jiang enjoys challenges and switches on when there is a major blackout. Thankfully, it is not often that power outages occur here and Singapore has one of the fewest and shortest power outages of cities worldwide, as rated by international industry indices, thanks to Singapore Power’s world-class electricity and gas transmission, distribution and market support services. “When a power outage occurs, the immediate concern is to restore the supply to affected customers safely and quickly,” says Mr Chan, 32, who has worked for seven years with Singapore Power, which covers over a million Singapore industrial and domestic customers. His team looks after the operations and maintenance of electricity distribution networks in the southern region of Singapore, which covers the Orchard Road shopping belt, Sentosa and the Central Business District area. The daily work, which he calls an unpredictable challenge, includes maintenance, repair and renewal of power equipment such as switchgear, transformers and power cables of various voltages from 400V up to 66kV deployed in the various electrical substations. “We also have to respond expeditiously to any power outages or incidents that occur at any time and restore electrical supply to affected customers,” he adds. “I have been here seven years, there is never a typical day at work. I’m always learning and growing in my job.” He relishes “bigger challenges” in national and regional projects, citing the National Day Parade (NDP) 2010 and Guangzhou 2010 Asian Games which “gave me the chance to hone my technical skills”. His role in the technical support committee for NDP 2010 was to ensure there were no power outages in the vicinity of the surrounding parade area and to have quick restoration of power supply in the event of any supply failure. Going to Guangzhou for a week for the Asian Games was “another breathtaking challenge” after China Southern Power Grid wanted condition monitoring work on the power supply infrastructure for the Guangzhou Asian Games. “I was part of the team carrying out cable diagnostic tests on the Guangzhou power network. During the trip, we shared our experience in condition monitoring with our counterparts and I also learnt about their work processes and network equipment. This was indeed an eyeopening experience.” Mr Chan studied at Raffles Institution and Victoria Junior College, after which he earned a degree in electrical engineering at the National University of Singapore. He joined SP Power- Grid soon after graduation and was posted to the Regional Network South as an executive engineer. His work philosophy is delivering quality work without looking at the clock. He says: “I think one key quality is the willingness to go the extra mile to ensure that the work carried out is up to mark. Any slip-up will not only affect the company’s performance, but could also potentially affect a very large customer base or in the worst case, cause a safety hazard to the public.” We also have to respond expeditiously to any power outages or incidents that occur at any time and restore electrical supply to affected customers. I have been here seven years, there is never a typical day at work. I’m always learning and growing in my job. — Mr Chan Hong Jiang, principal engineer, Singapore Power He is appreciative that his wife, Candy Ho, 29, a financial planner, supports his “unpredictable and challenging work hours”. “Occasionally I have to work at night and during weekends to handle emergency repairs or electricity supply shutdowns which take place only when the customer premises are empty,” he says. “My wife is very understanding and offers a lot of encouragement and support. This spurs me on to complete my work quickly and safely so that I can go back to my family as soon as possible.” His role model is his 62-year-old father, Mr Chan Teck Chua, whose work attitude, despite minimal education, was exemplary as an auxiliary salesman. “My father, a quiet and humble man, has been a good role model for me,” he says. “Although he did not receive much education and did not have a well-paying job, he worked very hard and lived frugally to provide for the family, something which he did very well and with much pride. I am trying to do the same for my wife and, in the future, for my kids.” Mr Chan’s work philosophy is delivering quality work without looking at the clock. PHOTO: CHONG JUN LIANG

However, the provision of a direct service connection is dependent on the available network capacity in the vicinity. If there is insufficient capacity, the customer is required to provide a substation for the connection. 1.4.2 For a larger load requirement exceeding 280kVA (400A), the customer has to provide a substation for SPPA to install necessary equipment to cater for the load. 1.5 Domestic Premises and Load Requirement not exceeding 45kVA 1.5.1 For premises where the electricity meter has already been installed by SPPA and no extension or rewiring work is required, customer may submit for an opening of utilities account to SPSL directly. Turn on of electricity service connection will happen on customer’s requested turn on date, subject to availability of appointment slots. 1.5.2 For premises where there is no electricity meter or where extension or rewiring work is required, the customer has to engage a LEW and submit an application for load connection. 1.6 Meter 1.6.1 All meters required for measuring a customer’s electricity consumption and demand (where applicable) are provided and maintained by SPPA. The customer has to provide meter boards, compartments, kiosks, etc. as SPPA requires them for the installation of its metering equipment. 1.6.2 Master- And Sub-Metering (a) A “Master-meter” is a meter measuring the consumption for all units and common areas in a building or cluster of buildings, which are used or occupied by multiple consumers. For master-metering scheme, the common services load must be at least 10% of the total load for the premise. (b) A “Sub-meter” is a meter measuring the consumption for a unit in a building or cluster of buildings used or occupied by multiple consumers, whose electricity is taken through a Master-meter. (c) A master and sub-metering scheme is applicable for multi-tenanted premises. Under this scheme, the electricity supply is metered at the intake point and each tenant’s supply is also separately metered and billed under the appropriate tariff. The owner/ developer/ landlord shall be billed for the difference in the consumption between the consumption metered at the intake point and the 3 summated consumption of the tenants. Where the owner/ developer/ landlord takes supply at high tension and is responsible for stepping down the supply to 230V/ 400V for distribution to tenants, a rebate of 2.5 % on the summated consumption of the tenants will be granted. (d) The owner/developer/MCST/landlord is to ensure that the owners (for selfoccupied units) or tenants (as the case might be) of individual units apply for the requisite utility account immediately upon taking possession of such units. The owner/developer/MCST/landlord is to maintain strict access controls over the switchboard, which contains the switches for the electricity supply from the main supply received from the network operator to the individual units at the supplied premises. The owner/developer/MCST/landlord shall be responsible for any charges arising as a result of unauthorised consumption of electricity by individual units or otherwise in the supplied premises. 1.6.3 Multi-Metered Premises The following are categories of multi-metered premises: (a) Residential premises which have landlord and tenant supply connections (b) Commercial complexes which have landlord and tenant supply connections (c) Multi-storey factories or industrial complexes which have landlord and tenant supply connections (d) All multi-metered premises fall under the Master and Sub-metering scheme with the exception of HDB residential premises. 1.7 Tariffs for Non-Contestable Customers 1.7.1 Tariffs are currently charged for low tension, high tension and extra-high tension electricity consumption. 1.7.2 Tariffs are subject to change and are published by SPSL quarterly. Online information on the latest electricity tariffs is available at www.spgroup.com.sg. 1.8 Payments for Electricity Charges by Contestable Customers 1.8.1 Contestable customer pays to SPSL or authorised retailers, charges for electricity consumption as ascertained by meters, and transmission charges and other fixed charges as determined by SPSL. Payment for electricity charges must be made on or before the due date specified in the bill. 1.9 Opening Account and Payment of Security Deposit for Use of System (UOS) Charges 1.9.1 The customer must open an account and place a security deposit for UOS charges with SPSL upon application for energisation of service connection. 4 1.10 Termination of Account 1.10.1 Non-contestable customers must give 4 business days' notice and contestable customers must give 7 business days’ notice to terminate an account. Termination can be submitted to SPSL via the digital channels available, unless the contestable customer is under an electricity retailer which in this case termination should be submitted to the electricity retailer. The customer must also request for removal of service cable (if necessary) upon notice to terminate the account. Upon receipt of a completed form, electricity supply will be terminated on the 8th business day for contestable customers. For High-Tension (HT) consumers, LEW is required to be present and to ensure the premise is ready for cut-off on the appointment date. 1.11 Disconnection of Service Cables upon Termination of Account 1.11.1 Disconnection work involves the de-energisation of service cables. It may also involve the removal of service cables and/or equipment if they are no longer required. 1.11.2 Where the removal of service cables and/or equipment is involved, the following are indicative lead times for the work: (a) After the de-energisation of LT service cable, the lead-time is about 5 business days for the removal of LT service cables where road-opening work is not involved. (b) Where road opening work is involved, a lead-time of 2 months is required. (c) After the de-energisation of 6.6KV and 22KV service cables, the lead-time is about 3 months. (d) For disconnection of 66kV and 230kV service cables, the lead-time for the deenergisation of service cables/ equipment is about 10 business days, subject to the approval of the Power System Operator (PSO). The subsequent removal of service cables and equipment will depend on the operational requirement and approval of the PSO. 1.11.3 Customers should take note the disconnection of service cables and termination of account are separate process. The respective lead time required must be catered for by the customer to the respective SP entities. 1.12 General 1.12.1 The customer agrees to comply with the terms of this document and to procure that its officers, agents and representatives shall so comply. 1.12.2 None of SPSL, SPPA, SPPG, Singapore Power Limited or any of Singapore Power Limited's affiliates (a "SP Entity") will be liable (including without limitation, for negligence or any other category of liability whatsoever) for any action taken by any of them under or in connection with the matters arising under or out of this document. No customer or any of a customer's officers, employees, agents or other representatives may take any proceedings against any officer, employee or agent of any SP Entity in respect of any act or omission of any kind by that officer, employee or agent in relation to any matter arising under or out of this document. 5 1.12.3 Each of SPSL, SPPA and SPPG retains the right, at its sole and absolute discretion, to amend, vary and/or supplement any terms of this document from time to time and its interpretation of any terms of this document shall be final and binding. 1.12.4 No failure on the part of each of SPSL, SPPA and SPPG to exercise, and no delay on its part in exercising, any right or remedy under this document will operate as a waiver thereof, nor will any single or partial exercise of any right or remedy preclude any other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies provided to SPSL, SPPA and SPPG in this document are cumulative and not exclusive of any other rights or remedies (whether provided by law or otherwise). 1.12.5 Nothing in this document shall in any way affect the obligations of a customer and its officers, employees, agents or other representatives to comply with applicable provision of the Electricity Act and all regulations and codes promulgated thereunder. 6 2. Application For Load Connection 2 Application for Load Connection 2.1 Load Connection 2.1.1 Each premise, as identified by the house or block number issued by IRAS, is limited to a single customer intake connection point. For modification of connection (such as upgrading of the load requirement) to existing premises, the customer is required to amalgamate all existing service connection into one intake. 2.2 Consultation 2.2.1 For developments in the initial planning stage, the customer is advised to seek consultation with SPPG to ascertain SPPA‘s requirements for a new or modified connection to the transmission system.

Please refer to Singapore Power (SP) eBusiness Portal for more information. 2.4 Processing of Application 2.4.1 Generally, SPSL responds to applications within 10 business days. 2.4.2 The responses are made according to the following customer categories: (a) Contestable Customer • A Consumer Connection Agreement, containing the service connection charge payable, the offer letter and the standard terms and conditions with respect to the distribution service connection. • If a substation is required, a letter stipulating the requirements will be forwarded to the customer. It will be followed by an Agreement subsequently after the substation plans are endorsed. (b) Non-Contestable Customer • A Quotation, containing service connection charge payable and the conditions of service with respect to the distribution service connection. • If a substation is required, a letter stipulating the requirements will be forwarded to the customer. A Supply Agreement including the service connection charge payable and the terms & conditions with respect to the distribution service connection, is offered after the substation plans are endorsed. 2.5 Commencement of Work 2.5.1 SPPG commences work only when the Agreement has been signed and received by SPSL, together with payment of service connection charges. 2.6 Type of Premises 2.6.1 Multi-Metered Premises (a) Multi-metered premises are premises where the landlord/ MCST (i.e. a mastermetered consumer or directly connected consumer) receives bulk intake service connection from SPPA, and transforms/ reticulates the supply to all the tenants (i.e. sub-metered consumers) within the premises. Any application for new or modified connection (includes upgrading) for the bulk intake to the multi-metered premises must be made by the landlord through its LEW. (b) A master-metered consumer means a consumer that is responsible for the common usage of a master-metered installation, which is connected to the transmission system. 8 (c) A master-metered installation means an installation in which supply is received by a master-metered consumer and sub-metered consumers (d) A master-metered installation shall have an independent address and its own dedicated access. (e) A sub-metered consumer means a consumer, other than a master-metered consumer, that receives supply in a master-metered installation via the electrical system owned by a master-metered consumer. 2.6.2 The landlord/ MCST or HDB, in the case of HDB premises, must ensure that the total applied load requirement for service connections to the multi-metered premises meet the total existing and future load requirements for all tenants. All tenants applying for any upgrading of load must do so through their master-metered consumer. In this regard, the master-metered consumer must approve the load of all tenants within the premises. 2.6.3 If the landlord’s existing approved load is insufficient to cater for the tenants’ load requirement, the landlord, as a master-metered consumer, must submit an application to SPSL for modification (upgrading) of service connection to the existing premises. In this case, the existing service cables are amalgamated with the new intake. Hence, there will not be separate direct connections to the tenants of such premises. 2.7 Premises in Private Housing, Industrial Estates, Commercial Developments Requiring Provision of Low Tension (LT) Distribution Network 2.7.1 For connection to premises where several parcels of land are to be sold or leased individually, one or more substations must be provided by the developer. Where the individual parcels of land are to be sold prior to development of these substations, details of the substation requirements and approved load must be included in the sales agreement by the future land parcel’s owner or lessee. 2.7.2 The developer must provide the development’s total load requirement and include the breakdown of the individual premises’ load requirement (as specified in the sales agreement) and the communal load requirement, if applicable. 2.7.3 In the case of landed housing estate development, the LEW must liaise with relevant Authorities, applicant’s appointed Architects/Civil & Structural Qualified Person and owner of the house for the siting of proposed overground distribution boxes on turfed areas. SPPA will provide and install the LT distribution network and service connection cables for the development. 2.7.4 Premises Involving Temporary Connection with Provision of Substation: (a) Special terms and conditions apply in such cases for temporary connection to construction worksites and other temporary premises. The term granted for temporary connection is usually 24 months. (b) Where there is a need for the provision of a temporary substation, the customer must provide the site and construct the structure of the substation according to the requirements of SPPA. 9 (c) There will be a need to install the necessary cables and equipment to facilitate the temporary connection to the distribution network. The customer pays outright costs for the cables and a monthly hiring charge for the use of the equipment during the term for temporary connection. 2.7.5 Developers are advised to connect residential developments to the LT distribution network. Opting for a HT supply intake setup will subject the landlord/MCST to the following: (a) Monthly Contracted Capacity charges (b) Operating costs associated with HT equipment setup 2.8 Provision of Substation 2.8.1 When an application for load connection necessitates the provision of a substation (Appendices 9 and 10), a site must be provided and a substation constructed by the customer at its own cost. 2.8.2 The customer can either choose his substation to be a dedicated or non-dedicated one (Appendix 35). If the customer opts for a dedicated substation, he has to inform SPPG when he applies for connection. Otherwise, it shall be assumed that the substation would be non-dedicated. 2.8.3 The substation is to be sited at an inconspicuous location, away from the main entrance of the development and major public roads. It is recommended to harmonise, blend and integrate the substation with the overall design of its development. The siting of the substation must ensure continuous and unobstructed vehicular access to the substation and the associated lead-in pipes at all times, to facilitate equipment delivery, operational activities, maintenance and cabling works by SPPG. 2.8.4 SPPG’s officers and vehicles will have full and unrestricted access to the substation at all times (Appendix 15). 2.9 Service Connection Cables 2.9.1 Generally, SPPA supply, install and maintain customer service cable. However, if the customer’s switchroom is not abutting to SPPA’s switchroom or at different level to the substation building, or service cable to be installed in cable tray/ ladder, or the cable termination to the customer switchboard is not via bottom entry, the customer shall supply, install and maintain the service cable. In the event that customer supplies the service cable, the customer’s LEW shall ensure that the service cable complied with SPPA cable specification, and submit cable sample and specification to Distribution Engineering Section for approval prior to procurement. The general type of cables for service connection is shown in Appendix 36. 2.9.2 For service cable that is supplied, installed and maintained by SPPA, customer shall provide UPVC lead-in pipes from intake point to 300mm beyond boundary line or the roadside drain abutting public road at a depth not exceeding 2.0m from the finished road level.
