Is solar energy efficient in Macau?

However, in the view of Macau-based scholar Wai Ming To, interviewed later in this special report, “Macau is a small city and has many high-rise buildings. Thus, solar energy is not efficient due to the shadowing effect of adjacent buildings and the small ratio of rooftop area to total floor area.

Can Macao increase solar energy?

The Macao government also sees an opportunity to increase solar energy. To encourage the installation of PV systems, officials passed a set of safety and installation regulations in 2015.

Does Macao have a photovoltaic energy contract?

The regulations require investors to enter into a 20-year contract for the purchase of photovoltaic energy with Macao’s sole energy service provider, Companhia de Electricidade de Macau (CEM). Essentially CEM will purchase the electricity produced to ensure investors profit within a reasonable period.

What is Cem doing in Macau?

In Macau’s Dawan District, CEM is currently involved in constructing renewable energy sources such as offshore wind power and solar photovoltaic power generation. It’s also involved in building hydropower renewable energy, such as pumped storage and natural gas combined-cycle power generation projects.

What is the new energy ecosystem in Macau?

CEM believes that adequate stability, affordability, and clean efficiency are the three core elements of the new energy ecosystem. Given Macau’s high cost of land and mature economy, the SAR Government formulated an energy supply strategy with CSG as the main supplier, supplemented by local power generation.

Does offshore wind energy make sense in Macau?

“In our view, as external observers, offshore wind energy in Macau’s territorial waters makes sense, as does the development of distributed generation of photovoltaic energy. Macau has a lot of sun and many roofs. There is a potential to develop this vector in the medium-to-long term.”
