The Ministry of Economic Affairs last week kept most renewable energy feed-in tariffs (FIT) for this year unchanged and eased cuts to solar energy subsidies, highlighting the government’s determination to catch up after delays in solar panel installations amid rampant bribery scandals.
The adjustments in solar energy tariffs have been in the spotlight, as solar is one of the most widely adopted renewable energy technologies in Taiwan, compared with geothermal, marine energy, and biomass and waste-to-energy.
In addition, a series of scandals surrounding the bidding process and protests by local farmers over the past two years have raised the question of whether it is time to review solar subsidies. Some radical thinkers even called for the government to cut its support.
As the government is committed to its energy transformation policy and net zero carbon emissions by 2050, no hasty actions should be undertaken. The government’s latest FIT arrangements for solar are agreeable, as they extend to small and micro-scale rooftop installations. To encourage such installations, the ministry trimmed a mere 2.1 percent for systems with capacity of 10 to 20 kilowatts, eschewing the 6 percent cut its pricing formula mandated.
It kept the tariff rate for small-scale rooftop systems, those with less than 10 kilowatts of capacity, at NT$5.7055 (US$0.17) per kilowatt-hour to incentivize households to adopt sustainable energy systems.
The ministry’s actions are in line with new subsidies approved early last month of up to NT$300,000 for household installations as part of the central government’s efforts to stimulate demand. The project is expected to lead to NT$72 billion in additional solar investments and would benefit about 120,000 households.
Meanwhile, the FIT for ground-mounted solar projects are to be cut the most, at more than 5 percent, amid dwindling demand and their unpopularity among local farmers.
The new subsidy scheme is comprehensive, as usable land is so scarce in Taiwan. It takes a lot of effort to persuade land owners to participate in large-scale solar projects, even if they have land that is underutilized or even fallow. People also fear their property being devalued if ground-mounted solar systems are built near it.
When the data from last year are compiled, they are expected to show that overall installations plummeted more than 30 percent to 1.8 gigahertz from 2023, as local governments have become hesitant to grant construction permits for new projects after multiple cases of officials being found guilty of accepting bribes in exchange for bidding information.
Taiwan had about 12.8 gigawatts of installed solar capacity, according to 2023’s data, so 3.6 gigawatts is needed from last year and this year to hit the goal of 20 gigawatts in 2026.
The inertia at the local government level was unexpected, as most solar companies were eyeing a recovery from a 2023 slump after the Democratic Progressive Party won last year’s presidential election. A slowdown was unsurprising while the political landscape was being decided, as some of the presidential candidates had expressed doubts about the government’s renewable energy policy.
The latest renewable energy subsidies are just a small step in shaping Taiwan’s energy policy. More drastic measures and collaboration from all parties are required to reach the goal of boosting the contribution of green energy to 30 percent by 2030.
What began on Feb. 28 as a military campaign against Iran quickly became the largest energy-supply disruption in modern times. Unlike the oil crises of the 1970s, which stemmed from producer-led embargoes, US President Donald Trump is the first leader in modern history to trigger a cascading global energy crisis through direct military action. In the process, Trump has also laid bare Taiwan’s strategic and economic fragilities, offering Beijing a real-time tutorial in how to exploit them. Repairing the damage to Persian Gulf oil and gas infrastructure could take years, suggesting that elevated energy prices are likely to persist. But the most
In late January, Taiwan’s first indigenous submarine, the Hai Kun (海鯤, or Narwhal), completed its first submerged dive, reaching a depth of roughly 50m during trials in the waters off Kaohsiung. By March, it had managed a fifth dive, still well short of the deep-water and endurance tests required before the navy could accept the vessel. The original delivery deadline of November last year passed months ago. CSBC Corp, Taiwan, the lead contractor, now targets June and the Ministry of National Defense is levying daily penalties for every day the submarine remains unfinished. The Hai Kun was supposed to be
Most schoolchildren learn that the circumference of the Earth is about 40,000km. They do not learn that the global economy depends on just 160 of those kilometers. Blocking two narrow waterways — the Strait of Hormuz and the Taiwan Strait — could send the economy back in time, if not to the Stone Age that US President Donald Trump has been threatening to bomb Iran back to, then at least to the mid-20th century, before the Rolling Stones first hit the airwaves. Over the past month and a half, Iran has turned the Strait of Hormuz, which is about 39km wide at
There is a peculiar kind of political theater unfolding in East Asia — one that would be laughable if its consequences were not so dangerous. Chinese Nationalist Party (KMT) Chairwoman Cheng Li-wun (鄭麗文) on April 12 returned from Beijing, where she met Chinese President Xi Jinping (習近平) and spoke earnestly about preserving “peace” and maintaining the “status quo.” It is a position that sounds responsible, even prudent. It is also a fiction. Taiwan is, by any honest definition, an independent country. It governs itself, defends itself, elects its leaders, and functions as a free and sovereign democracy. Independence is not a
