This past weekend, the clean energy industry was stunned by a major shift in the Senate’s latest draft of the One Big, Beautiful Bill Act, which introduced significant changes that could reshape how utilities plan and invest in renewable energy.
First, the bill now stipulates that wind and solar projects will only qualify for tax credits if they are placed in service by the end of 2027. Previously, eligibility was based on the construction start date, giving utilities more flexibility in planning long-term projects. This change compresses timelines and adds pressure to accelerate development or risk losing critical incentives.
Second, and even more unexpectedly, the bill includes a new excise tax on clean energy projects that use a certain percentage of components sourced from China. Given that China is the leading supplier of critical minerals, batteries, and other essential components, this provision could significantly disrupt supply chains and increase project costs.
These changes are more than just policy shifts—they’re strategic inflection points. Utilities must now re-evaluate their capital plans, assess the viability of projects already underway, and model multiple financial scenarios to prepare for both current and future rate cases. The ability to pivot quickly and deliver detailed, data-driven insights to internal stakeholders will be essential.
At PowerPlan, we’re seeing our customers take proactive steps: reviewing five-year capex plans, reassessing supply chain dependencies, and preparing for increased scrutiny from regulators and investors alike. With the growing demand for energy—especially from data centers and electrification—utilities must balance innovation with affordability more carefully than ever.
The organizations that can adapt with agility, supported by trusted systems and transparent financial modeling, will be best positioned to navigate this evolving landscape and continue delivering value to their customers.
