With federal tax credits under threat and regulatory stability in short supply, Bala Nagarajan, managing director of the energy investments team at S2G Investments, explained what he looks for in a company. "Is the product or the solution sold by this business cheaper, faster, better than the incumbent solution?" he asked. If so, it's worth considering. If not, the investment may not be a fit. His team heavily discounts any business case that depends on policy incentives. The message for entrepreneurs: build something that wins on its own economics first, and treat incentives as upside rather than a foundation.
Speaking as a guest on The POWER Podcast, Nagarajan introduced the concept of "anti-fragile businesses"—companies whose value propositions can withstand geopolitical shocks, policy reversals, and economic downturns. His showcase example was Aerones, a portfolio company that uses robots to repair wind turbine blades. The thesis: there is an enormous existing fleet that needs maintenance, qualified technicians are scarce and expensive, and the work is dangerous. A robotic solution that is cheaper, faster, and safer represents exactly the kind of durable opportunity S2G seeks.
For most of Nagarajan's 17-year career in energy, demand growth was gradual, tied to long-horizon electrification trends in homes, transportation, and manufacturing. AI data centers have compressed that timeline dramatically. The demand for new electrons "is knocking on our doors today," he said. This surge, combined with constrained supply, has created a dynamic that many believe will keep power prices high for a long time. S2G prefers skepticism. "What if things change?" Nagarajan asked. "How well will our underwrite hold up in the midst of potential changes?"
Where is investor enthusiasm strongest? Grid-enhancing technologies. Rather than building new generation capacity, the market wants solutions that make the existing grid better—advanced conductors, grid-enhancing software, and solid-state transformers. Conversely, the "power-to-X" sector—green hydrogen, sustainable aviation fuel, and similar products relying on cheap clean electricity—is struggling as rising power prices undermine their economics.
The gap between well-capitalized developers and smaller players is also widening. Only developers with deep balance sheets can afford to "Safe Harbor" equipment—purchasing materials early to lock in expiring tax credit incentives. Smaller developers are being forced to sell projects or abandon them, driving capital toward established brands.
Nagarajan also suggested natural gas is no longer a bridge fuel. Given demand for gas turbines from hyperscalers and the signals from manufacturers like GE Vernova and Siemens Energy, gas is firmly embedded in the energy mix. The consequence, he argued, is that emissions will rise, driving significant demand for high-integrity carbon credits—a space he is personally bullish on.
His overarching message is one of disciplined optimism. The energy sector is experiencing a rare convergence of rising demand, constrained supply, and deep pools of capital. But the winners will be those who resist underwriting to today's enthusiasm and instead back businesses that can thrive regardless of which way the policy winds blow.
