Chip maker TSMC in collaboration with ARK Energy on Friday said it supposed to offer 20,000 gigawatt-hours of electricity from solar vitality.
Whereas that may sound expansive, or now not it is now not nearly as large as TSMC may have you imagine. The 20TWh sum is an aggregate spanning the mission’s 20-year time frame. In reality, TSMC and ARK Energy are targeting 1,000 gigawatt hours over a year from solar vitality. By our estimate that’s roughly equivalent to 114MW of effective vitality.
Of path the solar ideal shines for so many hours a day, so to hit that, we ask the actual deployed capacity will likely be a fair bit better to account for this. ARK tasks that the mission ought to tranquil lead to the installation of about 2GW of solar capacity inside three years. Calm, that’s nowhere near what TSMC’s 20,000GWh claims would lead you to imagine.
What’s more, TSMC has ideal actually committed to purchasing 500GWh of solar vitality from ARK annually. The alternative 500GWh of annual generation will likely be made available to TSMC’s suppliers to jointly subscribe to. In this regard, the mission is an apparent relate to now not ideal decrease TSMC’s greenhouse gas emissions (GHG), nonetheless catch its suppliers — which make a contribution in part to the foundry’s Scope 3 emission — to decrease their maintain.
As TSMC explains it, under the program, participating suppliers will likely be offered electrical evaluation and planning providers and products, as wisely as a 20-year provider agreement designed to decrease the overall capex expenditure and decrease the barrier to adoption. To us, this sounds a cramped like a community aquire.
“Thru this innovative joint procurement mannequin for renewable vitality, we join hands with our industry partners to promote a sustainable low-carbon semiconductor present chain,” J.K. Lin, SVP of information know-how and materials management at TSMC, said in a statement.

As altruistic as this will likely sound, or now not it is in TSMC’s passion for its suppliers to curb their GHG emissions. Or now not it is no secret that semiconductor manufacturing is a notoriously resource intensive industry. And, while the solar mission will inevitably make a contribution to TSMC’s stated goal of regain-zero emissions by 2050, achieving that goal is complicated by the semiconductor industry’s advanced present chains, many of which make a contribution to the company’s Scope-3, or indirect, emissions.
Scope-3 emissions are a major contributor to a company’s carbon footprint, as it takes into account the greenhouse gasses generated by the sale of goods and providers and products, the transportation of these providers and products, and the use of products over their lifetimes. This means that if suppliers curb their scope-1 or-2 emissions by deploying solar or purchasing a larger share of renewable vitality, TSMC’s scope-3 emissions will likely be diminished as wisely.
This is now not the primary time TSMC has asked its suppliers to clean up their acts. According to TSMC’s latest ESG file, or now not it is asked “excessive-vitality consumption suppliers” to pass GHG emissions inventories which have to be confirmed by a third party. The company has also asked its suppliers to dwelling annual targets for reducing their annual vitality consumption. And the company says or now not it is labored with its partners to tweak transport schedules to curb emissions from transport.
With that said, the realm’s largest chip manufacturer’s emissions remain considerable. In 2021, the Taiwanese giant reported roughly 16 million metric tons of combined GHG emissions. ®
