Clean Energy Consulting: A Guide to Building the Energy Infrastructure of Tomorrow

Energy is the backbone of modern infrastructure, powering industries, businesses, and households worldwide. With increasing demand and the urgent need for security, reliability, and sustainability, energy project execution has become more complex and essential than ever. Engineering, Procurement, and Construction Management (EPCm) firms play a crucial role in delivering efficient, cost-effective, and sustainable energy solutions. Their expertise spans multiple energy sectors, ensuring projects are designed, built, and maintained with the highest levels of efficiency and compliance. 

The Role of Energy in Modern Infrastructure and What is Energy Management

Energy is fundamental to modern economies, supporting industries such as manufacturing, healthcare, transportation, commercial and smart buildings. Efficient energy management is essential to ensure cost-effectiveness and environmental sustainability. EPCm firms help businesses adopt energy-saving solutions, such as optimizing existing energy infrastructure, implementing combined heat and power systems, and integrating renewable energy sources. 

Definition and Difference Between Power and Energy

In the EPCm world, power and energy have different definitions which are important to understanding the work in various industries. Power is typically referred to as electrical energy only within an electrical utility’s infrastructure, Energy can be all inclusive of various types of energy, including chemical energy, oil and gas, nuclear energyrenewable energy, electrical energy, and more. It’s important to know and understand the difference between these two terms when working in different industries and on different projects.  

Understanding the Energy Landscape and ESG Principles

As global energy demands grow and sustainability becomes a top priority, understanding the evolving energy landscape and Environmental, Social, and Governance (ESG) principles is essential. Here we explore the trends shaping energy production and consumption, including the balance between renewable and non-renewable sources, and the regulatory factors influencing project development. 

Global Energy Demand and Current Supply Trends

Energy demand is rising due to urbanization, industrial growth, and technological advancements. Emerging economies are expanding their energy infrastructure, while developed nations focus on reducing reliance on fossil fuels and integrating renewables. EPCm firms must navigate these shifts, ensuring projects align with future energy needs and sustainability goals.

Regulatory and Environmental Considerations

Regulatory frameworks vary across regions, influencing energy production, distribution, and consumption. Policies such as carbon pricing, renewable energy mandates, and emissions reduction targets shape project feasibility. Clients in every industry understand the impact their energy usage, and energy efficiency, has on the environment and the grid as a whole. Being conscious of usage and efficiency helps make smarter decisions on project investments. EPCm firms must also stay informed about evolving policies to ensure compliance and maximize investment returns for clients. 

Energy Project Lifecycle in EPCm

Executing energy projects requires a structured approach to ensure efficiency, cost-effectiveness, and compliance with industry regulations. EPCm firms oversee the entire lifecyclefrom initial feasibility studies to long-term maintenance. This helps companies navigate complex challenges such as supply chain constraints, regulatory requirements, and technological integration. By leveraging strategic planning, engineering expertise, and advanced project management tools, EPCm firms play a critical role in delivering sustainable and resilient energy infrastructure.

How the Cost of Energy Affects Various Industries

Energy costs play a critical role in shaping the operational expenses and competitiveness of industries worldwide. Fluctuations in energy prices can impact everything from production costs to supply chain stability and long-term investment strategies. Industries with high energy demands, such as manufacturing, refining, and chemical processing, are particularly vulnerable to price volatility. Understanding how energy costs influence different sectors allows businesses to implement efficiency measures, explore alternative energy sources, and develop strategies to mitigate financial risk.

Wind Energy Transmission in the Texas High Plains


The Texas High Plains is a major hub for wind energy, with over 11,000 turbines generating electricity for millions of homes. However, transmission constraints have historically limited the ability to transport this energy to other regions, leading to curtailment and inefficiencies.

To address this, Texas implemented the Competitive Renewable Energy Zones (CREZ) initiative, constructing 345 kV transmission lines capable of moving 18.5 GW of electricity. Despite these efforts, the rapid expansion of wind energy has outpaced existing infrastructure, necessitating further investment.

In response, the U.S. Department of Energy announced a $1.5 billion investment in October 2024 to support four major transmission projects, including the Southern Spirit transmission line. This 320-mile project will connect the Electric Reliability Council of Texas (ERCOT) grid with southeastern U.S. markets, improving grid resilience and enabling broader utilization of Texas wind energy.

These initiatives are crucial for maximizing wind power potential, reducing curtailment, and ensuring a stable, renewable energy supply across the region.

15MW Combined Heat and Power Development at Midwest Refinery


A major Midwest refinery required a reliable and efficient power generation solution to enhance energy security and reduce operational costs. When integrated into the facilities the main power grid, added reliability and resilience are provided in the event of a utility power outage. For this project, a conceptual design was developed that provides 15 MW of power generation to reduce electrical energy supply costs, improve profitability and energy efficiency while maintaining a high level of electrical and steam supply reliability.

Nexus provided engineering and project management support for the development of a 15MW Combined Heat and Power (CHP) system. Nexus was challenged with evaluating and sizing steam generation from the CHP units that would displace steam generated by two existing utility boilers and the waste heat steam generation within the plant. The design required balancing the overall electrical and steam generation being produced within plant operational parameters to rely less on the electrical grid and be more sustainable, while providing for a cost-effective solution and a positive return on investment.

Nexus provided technical expertise needed by the owner to define the project scope and develop conceptual process and the electrical design basis parameters. Nexus also gathered specific equipment pricing which included gas turbines, heat recovery steam generators, gas compressors, electrical paralleling switchgear and powerhouse, black start generator, and CEMS/CHP system controls. The Project Team chose a two-train CHP/HRSG design to provide improved reliability for the plant. A trip of one turbine, providing 7.5 MW of generation, was felt to be within the ability of the current utility provider to handle the load shift without interfering with current facility operations.
