Energy Vault, an energy storage project developer, is pursuing growth in several competitive US power markets even as it tracks the regulatory implications of President Trump's executive order on the bulk-power system. The company's focus includes the Texas grid, PJM Interconnection, and the Southwest Power Pool, according to an executive.

The company is in the process of being acquired, adding another layer of complexity. The executive said Energy Vault must carefully navigate an uncertain regulatory backdrop, particularly the order, which could affect project development and power market rules.

The specific effects of the order remain unclear, but the company sees potential in these regions. The combination of market opportunities and regulatory risk will shape its strategy.
