====== EV Charger ======

===== Objective/ Status =====

**Project objective:** To install three (03) EV Chargers in Teresa Ville \\ 
**Current status (as at 26 Dec 2024):** //Phase II Milestone 2:// Presented the options available to Management Council for its review and further action

{{ :ev20241226.pdf | Issues and options/recommendations presented to MC on 26 Dec 2024}}
===== Background/ History =====

At Teresa Ville's 38th AGM held on Saturday 28 Oct 2023, it was proposed to study the feasibility of installing Electric Vehicle ("EV") charging points in the estate.

To guide MCSTs on issues surrounding this issue, the Singapore Land Transport Authority ("LTA") published a set of presentation slides "[[https://go.gov.sg/mcst-ev-guide|Electric Vehicle Guide for Management Corporation Strata Titles (MCSTs)]]" on 8 Dec 2023.

LTA has also published "[[https://www.lta.gov.sg/content/dam/ltagov/industry_innovations/Technologies/Electric_Vehicles/PDF/Electric_Vehicle_Guide_for_Drivers.pdf|Electric Vehicle Guide for Drivers]]" in 2024.

On Friday 12 Apr 2024, a few residents gathered to initiate an effort to investigate further into the feasibility of installing EV charging points in Teresa Ville.

Much of the discussion is happening over WhatsApp, then the essence of which will be summarised here in this wiki. To join the WhatsApp discussion, [[https://chat.whatsapp.com/IhafZo6LNVw24twaTJ5cjF|click here]].

On Saturday 19 Oct 2024, SPs at Teresa Ville's 39th AGM approved the following resolution:

"To consider and if approved, resolve by an Ordinary Resolution, to mandate the Management Council to:
  * execute leases of or rent, or licences of, any part of the common property for the installation of fixed EV chargers, for periods that do not exceed 10 years; and
  * re-designate not more than three (3) car park lots for EV charging use;

provided no management fund or sinking fund be used for the installation or uninstallation of any fixed EV charger in the common property."

**Key points:**
  * Locations:
    * 1 x 7.4kW beside Clubhouse
    * 2 x 22kW next to Block 1007 m/c lots
  * Finance: 20% profit sharing to the MCST – Option to channel it to the residents to lower down the chargeable rates.

==== NOVOWATT PTE LTD | WATT SINGAPORE ====

The company has an impressive track record of having secured contracts to install over 500 chargers at 150 condos all over Singapore. In addition to the proposed siting of chargers beside the Clubhouse, he also looked at how to site chargers beside the grass patch between Blocks 1005 and 1007, tapping on the ample supply at the latter block.

**Key points:**
  * Location:
    * 3 x 22kW next to Block 1007 m/c lots
  * Finance: 20% profit sharing to the MCST
    * Plan A (20% profit share)
      * EV owner pays: $0.62/kWh
      * EVCO share: $0.39/kWh
      * MCST share: $0.23/kWh
    * Plan B (15% profit share)
      * EV owner pays: $0.62/kWh
      * EVCO share: $0.41/kWh
      * MCST share: $0.21/kWh
    * Plan C (10% profit share)
      * EV owner pays: $0.62/kWh
      * EVCO share: $0.44/kWh
      * MCST share: $0.18/kWh

presented an intriguing possibility for consideration: that one of the 3 chargers be a fast-charging DC charger. While slow-charging AC chargers are suitable for residents' overnight EV charging, fast DC chargers open up the possibility for private-hire vehicles who can pop in for a quick 1 hour charge during the day and earn revenue for the MCST. Mr Wong Yew Kum cautions that we should be mindful of the much higher voltage (hence fire risk) for fast DC chargers.

**Key points:**
  * Locations:
    * 1 x 30kW DC charger beside Clubhouse
    * 3 x 22kW next to Block 1007 m/c lots
  * Finance: Assume 20% profit share for subscribers
    * DC Charger:
      * Subscriber EV owner pays: $0.672/kWh
      * EVCO share: $0.601/kWh
      * MCST share: $0.071/kWh
      * ---
      * Non-subscriber EV owner pays: $0.710/kWh
      * EVCO share: $0.631/kWh
      * MCST share: $0.079/kWh
    * AC Charger:
      * Subscriber EV owner pays: $0.456/kWh
      * EVCO share: $0.427/kWh
      * MCST share: $0.029/kWh
      * ---
      * Non-subscriber EV owner pays: $0.650/kWh
      * EVCO share: $0.581/kWh
      * MCST share: $0.069/kWh

===== Issues =====

==== Financing ====

As the AGM resolution explicitly requires that "no management fund or sinking fund be used", it means that the EVCO will have to incur the installation and any costs. E.g. if the EVCO decides to upgrade the power in the CSR at the clubhouse to support more charging capacity, they will have to incur this additional cost.

This section discusses how they recoup the upfront expenses.

=== Simple profit sharing ===

=== EVCO takes flat tariff ===

==== EVCOs input ====

During the voluntary familiarisation visits on 24 Oct 2024, the following EVCOs visited Teresa Ville:
  * **MNL Solutions EV** \\ looked at all the Electrical Switchrooms and observed that the one at Block 1001 (Clubhouse) is only single-phase and also insufficient capacity to support 3 EV charges. If we were to tap on this supply for 3 EV chargers, the supply will have to be load-balanced, i.e. reduced capacity, should all 3 chargers be used concurrently. Whereas the power supply at Block 1007 has sufficient spare 3-phased capacity to supply 3 EV chargers. ({{ :mnl_x_schneider_electric_ev_charging_solution_-_teresa_ville_-_27th_oct_2024.pdf |Presentation slides}})
  * **NOVOWATT PTE LTD | WATT SINGAPORE** \\ had visited Teresa Ville previously and he was updated on the developments (particularly AGM and resolution). The company has an impressive track record of having secured contracts to install over 500 chargers at 150 condos all over Singapore. In addition to the proposed siting of chargers beside the Clubhouse, he also looked at how to site chargers beside the grass patch between Blocks 1005 and 1007, tapping on the ample supply at the latter block.

The discussions are all very preliminary and all three EVCOs will work out more details for our consideration in the coming week or so. They also informed us that the Government's EV Charger Grant is quite popular: about half of the grant had already been snagged as of January earlier this year. If we wish to qualify, prompt action is advisable.

==== EV owners input ====

Chan Lap: I will use the DC charger (likely 1/2 time).
40 to 60 kWh per week, about 200 kWh per month.

Edwin Teh: DC would be a nice to have. Usageabout 50-60 kWh per week, 220 per month.

Ho Meng Kee: Yes, if is DC charger, I will use around 6 time per month, around $200/- to  250/- Per month.
If DC charger: Maybe 2 to 3 time Per month.

Caesar Bhandari: I would definitely use the DC charger a lot more if it was there. The other advantage of faster charging is that we will likely have higher throughput - people charging and then moving cars vs leaving them parked and charging for longer
