Big changes are underway in Hainan—and they’re designed to make everyday life smoother for residents, expats, and businesses alike. China's Hainan Free Trade Port will officially launch island-wide independent customs operation on December 18, 2025, completing its transition into a full-fledged Free Trade Port.
In April 2018, China announced plans to transform the island into a pilot free trade zone, with a long-term vision of developing a free trade port with Chinese characteristics. A master plan released in 2020 aimed to make Hainan a globally influential hub for high-level openness by mid-century.
Wang Yang publishes an official definition of a free port in the People’s Daily. Announcement of a free trade zone covering the entire island of Hainan during the 30th anniversary of the Special Economic Zone. Launch of the Master Plan for the construction of the Hainan Free Port, aiming for global status by 2050.
The "Notice on Preferential Corporate Income Tax Policies for Hainan Free Trade Port" proposed that enterprises in encouraged industries registered and operated in Hainan Free Trade Port shall be subject to a reduced corporate income tax rate of 15%.
2.3MWp grid connected photovoltaic array on Auckland Airport’s new outlet centre. Auckland Airport’s modern retail outlet centre, Mānawa Bay at opening had the largest rooftop solar system in New Zealand, on top of the 35,000m2 building.
There is about 200 MW of rooftop solar on residential buildings across New Zealand. The rest is commercial and industrial solar installations, where the business uses some or all of the solar generation on site. Any leftover generation is fed into the distribution network for other businesses and households to use.
At 2.3-megawatts, the solar array is expected to generate the equivalent of 80 per cent of the 100-store centre’s power usage. Auckland Airport’s Chief Commercial Officer Mark Thomson said sustainability is a core feature of the purpose-built premium outlet shopping centre.
Flyover of the Manawa Bay Outlet Centre roof-top solar, at Auckland Airport Mānawa Bay, Auckland Airport’s modern retail outlet centre, currently under construction, is set to have the largest rooftop solar system in NZ, at 2.3 megawatts.
A battery energy storage system (BESS), battery storage power station, battery energy grid storage (BEGS) or battery grid storage is a type of energy storage technology that uses a group of batteries in the grid to store electrical energy.
Battery energy storage capacity is the total amount of energy the battery can store, measured in kilowatt-hours (kWh) or megawatt-hours (MWh). Think of this as like the size of a water tank where you measure the water capacity in litres.
Battery storage duration describes how long the battery can discharge at its rated power. It’s calculated: Energy Capacity (MWh) ÷ Power Rating (MW). A 4 MWh battery with a 1 MW power rating has a 4-hour duration. A 1 MWh battery with a 2 MW power rating has a 0.5-hour duration. We’ve written about storage duration in more detail here.
Battery capacity is a core indicator of battery performance, representing the total amount of energy a battery can release under specific conditions, such as discharge rate, ambient temperature, and cutoff voltage. Battery capacity is usually expressed in three units: Ah (Ampere-hour), Wh (Watt-hour), and kWh (Kilowatt-hour):
