Media Release Temasek Cares Extends Its 'Stay Prepared' Initiative To Help Build Community Resilience In Singapore Singapore, Monday 5 May 2014 Temasek Cares is partnering Singapore Power and Singapore Post to extend its "Stay Prepared" initiative by encouraging individuals and families to be prepared for emergencies. Conceived by Temasek Cares with Singapore Power to prompt individuals and families to be prepared well ahead of any emergencies, a total of 1.2 million "Stay Prepared" Starter Kits will be distributed by Singapore Power and Singapore Post to all households in Singapore from 6 to 12 May 2014. Each "Stay Prepared" Starter Kit contains three 3M™ N95 face masks, instructions on how to wear the masks and emergency contact numbers. About 17,000 Starter Kits will also be delivered to charity homes, and another 300,000 Kits have been prepared on standby for needy families in case of severe haze or flu pandemic emergencies. Mr Richard Magnus, Chairman of Temasek Cares, said, “Singapore is a safe city. However, unforeseen events may adversely impact us and our community from time to time. All of us – individuals, families, companies – have to be prepared. For this reason, Temasek Cares wants to help build the resilience of our community, through its "Stay Prepared" initiative. “Temasek Cares is very pleased to partner Singapore Power and Singapore Post for this initiative to provide "Stay Prepared" Starter Kits to every household in Singapore. The Starter Kit includes three N95 masks so that each household can have an initial stock in case of a flu pandemic or severe haze from the forest fires in the region. We hope the Starter Kits will prompt individuals and families to develop their own emergency plans. The Starter Kit with the emergency contact numbers and the N95 masks can be useful additions to their family or personal emergency grab bags.” Mr Magnus added, “The Starter Kits programme is a significant step to fulfill Temasek Cares‟ vision of a resilient Singapore community – one that is ready for the unexpected, responds effectively to crises and recovers quickly from adversity. We will continue to come alongside people and partners in Singapore to create greater awareness of additional ways to be prepared. We believe such community initiatives are a useful way to complement national and individual efforts to keep Singapore safe.” Tan Sri Mohd Hassan Marican, Chairman of Singapore Power, said, “At Singapore Power, it is mission critical to respond to emergencies swiftly, safely and effectively. This readiness enables us to power every household and business in Singapore with world-class reliability, round the clock. We would like to encourage emergency preparedness among the community, so that it becomes second nature to everyone.” Tan Sri Hassan added, “We have mobilised our meter readers and technicians to distribute the "Stay Prepared" Starter Kits. We are running a call centre to address public queries on this effort. In addition, our staff volunteers will be distributing 17,000 starter kits to more than 140 charity homes for the elderly, disabled and other residential facilities . We would like to touch all facets of society in this outreach.” Mr Lim Ho Kee, Chairman of Singapore Post said: “We are happy to be part of this nationwide community effort to help Singapore households stay prepared. Over the next few days, some 1,200 postmen and postwomen will distribute the "Stay Prepared" Starter Kits to every HDB and high-rise household. As a responsible and trusted national postal service provider, SingPost remains committed to deploy our last mile delivery capability and resources to help with such meaningful initiatives.” Singapore Power has set up a hotline where members of the public can get information about the delivery of the "Stay Prepared" Starter Kits. The delivery hotline (Tel: 1800-738-2000) will be in operation from Monday 5 May 2014, to Saturday 24 May 2014, from 8.00 am to 8.00pm daily. If the "Stay Prepared" Starter Kit cannot be delivered to a postal address, residents will receive a delivery advice with information on where they can collect their Starter Kits. The "Stay Prepared" Starter Kits programme and the umbrella "Stay Prepared" initiative are backed by the Temasek Emergency Preparedness Fund, which was established by Temasek Holdings with an endowment of S$40m in March 2014, as part of its 40th anniversary community initiative. More information on the 'Stay Prepared' initiative is available at www.stayprepared.sg.

This charge varies for different load requirements and is categorised as follows: [a) Development Without Substation The service connection charge comprises the cost based on requirement in kVA of tapping supply from both the High Tension [HT) and LT networks, which includes the cost of service cables. For individual consumers without substations, the cost of LT service cable for the same capacity may vary widely depending on their locations with respect to the nearest LT mains. These consumers are not the sole beneficiaries of the extension of the LT network. To achieve a greater degree of equity in terms of cost for these general consumers, a standard cost approach is adopted by grouping consumers with similar supply requirements. The average global cost per kVA is determined based on past statistics. For example, this category of consumers which comprises mainly landed residential owners applying for the same applied load, will pay the same standard connection charge regardless of the location of their premises from the existing LT network. [b) Development With Substation The service connection charge comprises the cost based on requirement in kVA of tapping supply from the HT network and the cost of service cable. The cost of tapping supply from the HT network refers to the cost of cables and consumables used in setting up a new distribution substation. It excludes the cost of shared network assets such as switchgear, transformer and HT network cables. The cost is spread to all new consumers proportionally on a per kVA basis. For consumers with substations, their supply intake point is usually adjacent to the substation, which requires a service cable of approximately 15m in most instances. Therefore, the standard cost of service cable is computed based on a length of 15m. Consumers shall pay the additional cost for service cable exceeding 15m. In addition, consumers shall also pay for those dedicated assets, such as switchgear and transformers, which are serving them and do not benefit others.

For longer lengths, additional charges shall apply. Standard charges are only applicable to consumers who are connected to the shared network. Standard charges are not applicable to consumers where the network extension is unlikely to be shared by others. Some of these include supply to HDB premises, premises involving installation of bigger capacity cable in order to overcome the excessive voltage drop, temporary work sites, public installations and offshore island premises. These consumers will be required to pay for the full connection network cost, based on user-pay principle, as they are the main beneficiaries. B2 Service Connection Charges for HT, EHT and UHT Supply Consumers taking HT, EHT and UHT supply shall pay the cost of the service connections to their intake equipment including cables, associated equipment and facilities to effect the connection of consumers’ equipment to SPPA’s substation/network. The service connection shall cater for single contingency. Consumers requesting for additional level of contingency that exceeds the single contingency standard are required to pay for the full cost of such provision. B3 Dedicated Network/Substation The developer or consumer shall pay the full cost of all associated equipment and facilities under a dedicated network/substation scheme for which the network capacity is intended to serve the developer’s development or consumer’s premise(s) exclusively. A substation comprises land, building, electrical equipment and associated cables. A substation which serves a development or premise has to be provided and paid for by the developer or consumer. As the capacity of electrical equipment is lumpy, the substation may have excess capacity. The developer or consumer will carry the cost of this excess capacity which cannot be avoided. As this substation is required to serve mainly the development’s or consumer’s load, it is considered a dedicated substation. To reduce cost, a developer or consumer can choose to let SPPA bear the cost of the electrical equipment and associated cables, thus making the network/substation a nondedicated one. In return, SPPA must be allowed to allocate the excess capacity to other consumers. Even after the excess capacity is allocated, SPPA shall return the capacity to the developer or consumer if his demand grows later provided existing allocated capacity to other consumers can be diverted. The latter provision shall also apply to the decommissioning of the substation. At present, most substations provided by developers or consumers are non-dedicated substations.

These are consumers who choose to buy electricity from SP Group at the regulated tariff. 7 The Uncontracted Capacity Charge (UCC) applies in the event that the maximum demand in kW (measured by the half-hour integration meter) exceeds the Contracted Capacity. UCC applies to: (a) Normal customers without embedded generation; (b) Customers with embedded generation who require top-up supplies and opt to summate their kW output from embedded generation and kW demand from the network (i.e Summation Scheme) for determining maximum demand; and (c) Customers with embedded generation who require top-up supplies and opt to cap their power demand in kW drawn from the network (i.e Capped Capacity Scheme or Extended Capped Capacity Scheme). The UCC applies in the event that the maximum demand in kW (measured by the half-hour integration meter) exceeds the contracted capacity and shall be limited to 20% of the Contracted Capacity. 8 For Capped Capacity Scheme (CCS), the Uncontracted Standby Capacity Charge (USCC), at 5 times of Contracted Capacity Charge, applies in the event that the demand in kW (measured by the power meter) drawn from the network exceeds 120% of the contracted capacity for a duration of more than 10 seconds continuously. 9 For Extended Capped Capacity Scheme (ECCS), the 2-tier Uncontracted Standby Capacity Charge (USCC) applies as follows: • Tier 1: 5 times of Contracted Capacity Charge is applicable if the demand in kW drawn from the network exceeds 120% and up to 200% of the contracted capacity for a duration of more than 100 seconds continuously. • Tier 2: 12 times of Contracted Capacity Charge is applicable if the demand in kW drawn from the network exceeds 200% of the contracted capacity for a duration of more than 10 seconds continuously. 10 For both CCS and ECCS, the consumer shall at its own expense, install and maintain Load Limiting Device, in accordance with requirements that the Transmission Licensee may stipulate from time to time. * Based on power factor of 0.85 Notes On Use-of-System Charges Effective from 1 April 2018 1 Supply Categories The Use-of-System [UOS) Charges shall be paid for electricity transmission services at each metered intake supply point in accordance with the voltage at which a consumer receives the electricity supply. The UOS Charges are applicable for the following categories of supplies : • Low Tension [LT) Supplies at 400V/230V Supply to Low Tension-Small Consumer Supply to Low Tension-Large Consumer • High Tension [HT) Supplies at 22kV and 6.6kV Supply to High Tension-Small Consumer, whose Contracted Capacity is less than 1,700 kW per month at each metered intake supply point. Supply to High Tension-Large Consumer, whose Contracted Capacity is at least 1,700 kW per month at each metered intake supply point. • Extra-High Tension [EHT) Supplies at 66kV Supply to Extra-High Tension Consumer • Ultra-High Tension [UHT) Supplies at 230kV Supply to Ultra-High Tension Consumer • Temporary Supplies Temporary Supplies apply only to LT and HT supplies for temporary civil engineering and building construction sites. 2 Low Tension Supplies 2.1 Low Tension Small Consumer LT supplies [in kWh) to all non-contestable LT consumers are metered on a monthly basis. A flat per kWh UOS rate is levied at each metered intake supply point. These are consumers who choose to buy electricity from SP Group at the regulated tariff. 2.2 Low Tension Large Consumer LT Supplies to these contestable consumers are metered on energy (kWh) on a halfhourly time-of-day basis. The respective per kWh charges shall be levied at a “Peak” and an “Off-peak” period for the energy supplied at each metered intake supply point. 2.2.1 Peak Period Charge The Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the peak period, 7.00 am to 11.00 pm, in that month. 2.2.2 Off-Peak Period Charge The Off-Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the off-peak period, 11.00 pm to 7.00 am, in that month. 3 High Tension, Extra-High Tension and Ultra-High Tension Supplies For HT (i.e. HT Small and HT Large), EHT and UHT Supplies, UOS Charges shall be levied at each metered intake supply point as follows : a. Contracted Capacity Charge; b. Peak Period Charge; c. Off-peak Period Charge; d. Reactive Power Charge; e. Uncontracted Capacity Charge, and f. Uncontracted Standby Capacity Charge (applicable to consumers with embedded generation who opt to cap their power demand drawn from the network). 3.1 Contracted Capacity Charge 3.1.1 The Contracted Capacity Charge is a monthly charge payable in any month for the Contracted Capacity at each intake supply point of a consumer. The Contracted Capacity shall be the supply capacity (in kW), which is requested by the consumer for that intake supply point. For the avoidance of doubt, and without prejudice to paragraph 3.1.3 herein, the consumer shall not be allowed to reduce the declared Contracted Capacity upon the signing of the Consumer Connection Agreement / Supply Agreement, notwithstanding the fact that the energisation of the new supply has still not taken place. 3.1.2 For a new connection, consumers are subject to a binding period of 5 years from the target date or the commissioning date for SPPA’s plant and equipment, except for the service cable, whichever is later. During the 5-year binding period, no reduction to the Contracted Capacity is allowed. For new HT, EHT and UHT connections, the minimum Contracted Capacity for each intake supply point is as follows : HT with 1 or 2 feeders HT with 3 or 4 feeders EHT UHT 1,700 kW, 12,751 kW, 25,501 kW, 85,000 kW. During the first year of the 5-year binding period, requests for intermediate incremental steps of Contracted Capacity may be made before the full Contracted Capacity is implemented. The first step shall be at least one quarter ( 1 /4) of the consumer’s requested full Contracted Capacity at each intake supply point. 3.1.3 After the initial 5-year binding period, the consumer may, by giving at least 10 business days’ notice in writing, reduce his Contracted Capacity at each intake supply point subject to the following minimum values: HT with 1 or 2 feeders HT with 3 or 4 feeders EHT UHT 850 kW, 6,375 kW, 12,750 kW, 42,500 kW. Any such reduction in Contracted Capacity shall be subject to a 1-year binding period from the effective date of the revised Contracted Capacity, i.e. the consumer shall not be entitled to make any further reduction in the Contracted Capacity within one year following any such reduction. The Market Support Services Licensee will inform the consumer of the date of their billing cycle. The consumer will be billed based on the revised Contracted Capacity for the entire billing cycle that encompasses the effective date of the revised Contracted Capacity. 3.1.4 The consumer, may, by giving at least 15 business days’ notice in writing, may be allowed to increase his Contracted Capacity, during the 5-year or 1-year binding period. The revised Contracted Capacity shall apply for the remainder of the initial 5-year binding period or for a minimum period of 1 year, whichever is later, provided SPPA is not required to install new or additional equipment. The consumer will be billed based on the revised Contracted Capacity for the entire billing cycle that encompasses the effective date of the revised Contracted Capacity. Reduction of Contracted Capacity during binding periods will not be allowed. 3.1.5 A consumer whose revised Contracted Capacity requires SPPA to install new or additional equipment shall be considered as receiving a new supply with a new 5-year binding period. 3.1.6 Subject to Clause 3.1.4 and 3.1.5, the UCC incurred by a consumer in a particular month (“UCC Month”) can be converted into Contracted Capacity Charge provided: (i) (ii) (iii) (iv) The consumer submits the request for an increase in Contracted Capacity no later than 2 weeks after the date of the bill for the UCC Month; The revised Contracted Capacity is not less than the maximum demand recorded in the UCC Month; The revised Contracted Capacity does not require the Transmission Licensee to install new or additional equipment; and Upon approval by the Transmission Licensee, the revised Contracted Capacity shall take effect on the first day of the UCC Month and thereafter shall not be reduced within one year, or the remaining of the 5-year binding period, whichever is later. 3.1.7 For a new development with landlord and tenants, the Contracted Capacity required by the landlord himself and his tenants (HT and above) must in aggregate meet the minimum values set out in paragraphs 3.1.2 to 3.1.3 above in order for the landlord to qualify for HT, EHT or UHT supplies. If landlord or its tenants (HT and above) request to revise their Contracted Capacity, the aggregate Contracted Capacity after revision must meet the minimum Contracted Capacity values and subject to the same terms and conditions for revision of Contracted Capacity set out in paragraphs 3.1.3 and 3.1.4. 3.1.8 Existing HT, EHT or UHT consumers may have Contracted Capacity below the minimum Contracted Capacity as specified in paragraphs 3.1.2 and 3.1.3. For such consumers, they may request to increase (but not decrease) their Contracted Capacity in the manner as described above. 3.2 Peak Period Charge The Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the peak period, 7.00 am to 11.00 pm, in that month. 3.3 Off-Peak Period Charge The Off-Peak Period Charge payable shall be the monthly charge based on the energy (in kWh) supplied to an installation during the off-peak period, 11.00 pm to 7.00 am, in that month. 3.4 Reactive Power Charge The Reactive Power Charge is a monthly charge payable in any month for the installation's excess kVArh consumption. The excess kVArh shall be the difference by which the installation's kVArh consumption drawn from the network in that month is greater than 62% of its kWh consumption drawn from the network in the same month. 3.5 Uncontracted Capacity Charge 3.5.1 The Uncontracted Capacity Charge is a monthly charge payable in any month for the Uncontracted Capacity utilised. The Uncontracted Capacity is the capacity in kW by which the maximum demand in kW (measured by the half-hour integration meter) exceeds the Contracted Capacity at that metered intake supply point. 3.5.2 The Uncontracted Capacity Charge shall apply to the following HT, EHT and UHT consumers : a. Normal consumers without embedded generation; b. Consumers with embedded generation whose monthly maximum demand in kW is the maximum summated demand in kW in the month, determined by summating the kW demand drawn from the network and the kW output from embedded generation (i.e. Summation Scheme); and c. Consumers with embedded generation who opt to cap their power demand in kW drawn from the network in the event that the maximum demand in kW (measured by the half-hour integration meter) exceeds the Contracted Capacity at that metered intake supply point (i.e. Capped Capacity Scheme or Extended Capped Capacity Scheme). The Uncontracted Capacity for these consumers shall be limited to 20% of the Contracted Capacity. 3.6 Uncontracted Standby Capacity Charge 3.6.1 The Uncontracted Standby Capacity Charge is a monthly charge payable in any month for the Uncontracted Standby Capacity utilised. The Uncontracted Standby Capacity Charge shall apply to those HT, EHT and UHT consumers with embedded generation who opt for the Capped Capacity Scheme or Extended Capped Capacity Scheme. 3.6.2 For Capped Capacity Scheme, the Uncontracted Standby Capacity Charge applies in the event the demand in kW drawn from the network (measured by the power meter) exceeds 120% of the Contracted Capacity at that metered intake supply point for a duration of more than 10 seconds continuously. 3.6.3 For Extended Capped Capacity Scheme, the Uncontracted Standby Capacity Charge applies in the event : • the demand in kW drawn from the network exceeds 120% and up to 200% of the Contracted Capacity at that metered intake supply point for a duration of more than 100 seconds continuously; or • the demand in kW drawn from the network exceeds 200% of the Contracted Capacity at that metered intake supply point for a duration of more than 10 seconds continuously. 3.6.4 For the avoidance of doubt, in the event Uncontracted Standby Capacity Charge applies in accordance with Clauses 3.6.2 and 3.6.3 above, Uncontracted Capacity Charge shall also be applicable for the Contracted Capacity portion which is 20% above the customer’s declared Contracted Capacity. 4 Temporary Supplies Temporary Supplies apply only to LT and HT supplies for temporary civil engineering and building construction sites. The UOS charges applicable for the LT and HT temporary supplies shall be the same as those used for LT and HT supplies respectively. For temporary supplies at HT, the Contracted Capacity shall apply for a binding period of 2 years. Upward revision of the Contracted Capacity may be allowed during the validity of the binding period of the Contracted Capacity. The revised Contracted Capacity shall in such cases apply for a minimum period of 1 year, provided SPPA is not required to install new or additional equipment. Downward revision during such binding period will not be allowed. A consumer whose revised Contracted Capacity requires SPPA to install new or additional equipment, shall be considered as receiving a new temporary supply. The term granted for temporary connection is 2 years.
