MARSIM ENERGY LLC

Our team specializes in providing owner's engineering services by designing reliable and efficient power systems for large-scale commercial, industrial and utility projects. We conduct thorough power systems analysis to ensure design validation and compliance with industry standards and offer strategic technical advisory services that optimize performance to meet project demands. 

• We provide engineering and consulting services, throughout the project lifecycle, from early stage to COD. Our expertise encompasses power systems analysis and modeling using dedicated engineering software for tasks such as short-circuit analysis, equipment duty analysis, load flow, power quality assessments, protective device coordination, and arc flash risk assessment and mitigation. 
• We also conduct buildings assessments, define project scopes, and manage upgrades and retrofits, alongside feasibility studies. Additionally, we address facilities power distribution, covering normal, standby, and emergency systems, as well as buildings electrification.
• Our services extend to transportation electrification, planning for electrical vehicle deployment, and designing and implementing charging infrastructure. During project design, construction, and commissioning, our owner’s engineering services ensure effective execution. 
• We support early-stage project development with technical due diligence, evaluating and selecting power generation and energy storage technologies, conducting conceptual design to facilitate interconnection and permitting processes, and providing preliminary equipment sizing. Our work also includes electrical design review, optimization, and validation, alongside the development of technical specifications and major equipment (e.g., transformers, switchgears, generators) procurement support.

• Energy efficiency and high-performance facilities, commercial and industrial facilities, national laboratories, higher education and research facilities,  mission critical facilities.
• Sustainable transportation, smart mobility programs, electrical vehicles charging infrastructure.
• Sustainable clean energy/non-conventional power generation technologies: renewable energy, battery storage, fuel cells, emerging technologies.
• Conventional thermal power generation (combined cycle, cogeneration/CHP, gas-fired), microgrids, district energy plants, utilities, municipalities, substations.
• Decarbonization, air quality control systems, climate change initiatives studies.
• Water and wastewater treatment plants.
