For a project in Singapore the client are planning on purchasing Green RECs from TIGR. 

The Tradable Instrument for Global Renewables (TIGR) Registry is an online platform for tracking and trading RECs in Asia, Africa and the Americas. The Registry enables developers to generate, verify, and sell RECs. It allows buyers to source RECs anywhere in the world while managing all assets in a single online portal.

Will purchase from TIGR fulfill the credit requirement under option 2? 

For ready reference, option 2 states that: Engage in at least a 2 year renewable energy contract to purchase at least 8kWh per sq.ft.  per year from renewable  electricity sources.

Would appreciate it if someone can shed some light on this issue?
