In January 2017, Hong Kong published its Climate Action Plan 2030+, targeting a 65–70% reduction in carbon intensity by 2030 relative to 2005 and outlining a greater role for renewable generation.

The government signed new 15-year Scheme of Control Agreements with CLP Power and HK Electric, providing for feed-in tariffs and renewable-energy certificates from 2018. TerraHash's archived roadmap describes developing settlement systems for distributed rooftop solar.

The Water Supplies Department tested an early floating photovoltaic installation at Shek Pik Reservoir on Lantau Island in 2017, combining clean electricity generation with reduced surface evaporation.

To track variable rooftop and floating solar output, the archived project describes high-frequency inverter data gateways and grid-interconnection safety assessments supporting subsequent feed-in tariff deployment.

Construction of O-PARK1 at Siu Ho Wan on North Lantau was completed in 2017. The anaerobic digestion facility was designed to convert food waste into biogas and renewable electricity.

Its planned throughput was 200 tonnes of food waste a day, with a target to reduce carbon emissions by roughly 25,000 tonnes annually. TerraHash's archive describes real-time generation and grid-connected energy monitoring.

Biogas produced through anaerobic digestion varies in composition and heating value, creating challenges for stable generator output and grid synchronization.

The archived solution describes adaptive gas-control software deployed around O-PARK1 to reduce voltage swings and improve the stability of electricity supplied into CLP Power's grid.
