About this book:

From its origins in the mid-19th century as a collection of localized gas light and electric companies—including the Fort Wayne Gas Light Company, Ohio Fuel Gas, and the Northern Indiana Public Service Company (NIPSCO)—NiSource’s history mirrors the evolution of the American energy sector. Early predecessors navigated the transition from manufactured gas to natural gas and the "War of the Currents," gradually consolidating through the late 19th and early 20th centuries to achieve economies of scale and build regional infrastructure. These utilities powered the industrial transformation of the Midwest, weathered the Great Depression and World War II, and met the explosive demand of the post-war boom. The crucible of the 1970s energy crises and environmental legislation, followed by the deregulation of the 1980s, forced a strategic pivot toward efficiency and market responsiveness, culminating in the 1987 merger of NIPSCO and Columbia Energy Group to form NiSource, a diversified holding company positioned for the modern era.

Throughout the 1990s and 2000s, NiSource executed a strategy of aggressive growth through strategic acquisitions—such as Bay State Gas and the pivotal Columbia Pipeline Group—while navigating the complexities of FERC Order 636, electricity restructuring, and the Great Recession. The company leaned heavily into technological modernization, deploying Advanced Metering Infrastructure, distribution automation, and sophisticated data analytics to create a "smart grid" and enhance pipeline integrity management. Simultaneously, NiSource managed a dense web of state and federal regulatory relationships, securing rate recovery for massive capital programs aimed at replacing aging cast-iron gas mains, hardening the electric grid against severe weather, and maintaining cybersecurity resilience. This period solidified its status as an S&P 500 company, defined by disciplined capital allocation, a growing dividend, and a deliberate shift toward a pure-play regulated utility model to ensure predictable earnings and lower risk.

In the 2010s and 2020s, NiSource placed environmental sustainability and decarbonization at the core of its strategy, accelerating the retirement of coal-fired generation at NIPSCO in favor of wind, solar, and battery storage, while aggressively targeting methane emissions across its vast natural gas network through advanced leak detection and pipe replacement programs. The company embraced digital transformation across its enterprise, leveraging IoT sensors, predictive analytics, and cloud computing to optimize asset management and customer engagement. Workforce development, safety culture, and deep community partnerships remained central to its operational philosophy, ensuring a skilled labor pipeline and social license to operate during the energy transition. Leadership maintained a long-term vision focused on balancing reliability, affordability, and clean energy goals, actively exploring future fuels like hydrogen and renewable natural gas.

Looking forward, NiSource is positioning itself as an architect of the net-zero energy future, managing the complex interplay of electrification, distributed energy resources, and electric vehicle integration. Its strategy hinges on modernizing the grid into a dynamic, two-way platform capable of handling high renewable penetration, while utilizing its natural gas infrastructure as a flexible bridge and potential carrier for low-carbon fuels. By maintaining financial discipline, constructive regulatory engagement, and a commitment to innovation, NiSource aims to leverage its century-and-a-half of institutional knowledge and critical infrastructure to deliver shareholder value while powering a sustainable, resilient future for the communities it serves.
