Pick one — models revealed after.Both summaries are AI-generated. Massachusetts now requires data centers over 25MW to source 100% clean power on-site or pay penalties, a stricter rule than the state's 40% standard for other industries. This forces AI/LLM operators to either invest in costly renewable infrastructure (e.g., solar farms or battery arrays) or abandon expansion in a major tech hub, adding millions in upfront costs per facility and restricting locations for low-latency deployments. Data centers larger than 25 megawatts in Massachusetts will now be required to meet 100% of their electricity demand with clean energy generation, either on-site or through nearby construction, or pay into a ratepayer protection fund, directly impacting the operational costs and planning for LLMs and agents running in the state.
