Formulating a National Electricity Grid Code and the Definition of a Net Metering Policy in Timor-Leste

Formulating a National Electricity Grid Code and the Definition of a Net Metering Policy in Timor-Leste

Timor-Leste has a high potential for solar energy, particularly along the coastline with an estimated solar resource of up to 5.5-6 kWh/sq.m per day. As distributed generation grows, grid code requirements for DERs become increasingly important to ensure grid stability.

Solar resource assessments can gauge the potential volume of solar capacity that could be motivated through a net metering programme but typically needs highly resolved geographical information system (GIS) data on topography and land-use availability, solar resource data, and light detection and ranging (LiDAR) which can be used for mapping rooftop availability.


CTCN Support

Through this technical assistance, the Climate Technology Centre and Network will aimg to provide Timor-Leste with insights on solar resources, including expected capacity factors across the country, and will train the government entities on how to use these data to further refine resource potential.

By prioritizing the state-owned utility's specific needs in the selected areas, the expected activities of this technical assistance are as follows:

  • Development of implementation planning and communication documents.
  • Examine solar resource data for Timor Leste to provide insights into the renewable energy potential for the country.
  • Report detailing the solar resource potential insights for Timor Leste and providing capacity factors across the country for different solar configurations.
  • Develop a net metering policy for Timor Leste and calculate the payback period for solar projects under different scenarios.
  • Develop one GCF Concept Note for a full-scale project and In-person workshop and project wrap-up – Compiling training and final deliverables.
  • Develop the grid code, examining elements of IEEE 2800 and IEEE 1547-2018 that may help safely integrate inverter-based resources.
  • Grid Code for DERs and IBRs in Timor Leste - Assessment of Current Grid Codes and Character of Service in Timor Leste.
  • Grid Code for DERs and IBRs in Timor Leste - Examination of Grid Support Functions from Inverter Based and Distributed Energy Resources.
  • Report on Grid Code for DERs and IBRs in Timor Leste.


Expected Impact

With this technical assistance, the CTCN will assess the potential volume of solar capacity that can be generated through a net metering programme, and examine the capacity factors across the island for different solar PV configurations.


Seeking Experts

The UN Climate Technology Centre and Network (CTCN) is inviting its Network members to assist Timor-Leste in this initiative. Interested qualified firms are invited to submit an Expression of Interest (EOI) to participate in formulating a national electricity grid code and developing a net metering policy in Timor-Leste. Please refer to the detailed documents HERE and HERE.
