The Grid Promissory Note is commonly used in Hong Kong's energy sector when parties need to establish a formal payment commitment for grid-related services or infrastructure. This document type emerged from the need to combine traditional promissory note structures with specific requirements of power grid operations and services. A Grid Promissory Note typically includes detailed payment schedules, grid specification references, and may be used in scenarios such as new grid connections, infrastructure upgrades, or ongoing service payments. The document must comply with Hong Kong's Bills of Exchange Ordinance while incorporating specific technical and commercial terms relevant to grid operations. It's particularly useful in situations where phased payments are required for major grid infrastructure projects or when securing long-term grid service arrangements.
