Clean, Efficient and Resilient Energy Systems Addressing climate change challenges requires both mitigation and adaption strategies. The combination of energy and information technology innovations and renewable energy’s growing competitiveness are transforming the landscape of energy services. Technology cost reductions are leading to rapid growth in variable renewable sources of generation, requiring the electrical grid to be structured and operated differently to ensure a reliable supply. With increased capacity of solar, wind, energy storage, combined heat and power (CHP) and other distributed energy resources, there is an opportunity to enhance resiliency in critical areas. Deployment of more distributed generation resources and the development of new technologies, such as microgrids and energy storage, is growing to more efficiently match supply and demand and to augment renewables with other generation resources. Our power sector clients are also investing in improved physical and cybersecurity programs intended to assure better system performance during extreme weather and other catastrophic events. System hardening initiatives – particularly in areas hard hit by severe weather – and more stringent reliability standards are driving distribution system redesign. Severe weather events also generate a greater need for TRC storm damage assessment teams who provide distribution and engineering support to our utility clients. These teams mobilize to assess damage, develop power restoration plans, manage construction crews, clean up hazardous chemicals (e.g., PCBs from transformers and substations) and provide other support for restoration efforts. In 12 months, our Advanced Energy group managed projects that saved over 11 billion kilowatt-hours. That’s equivalent to… All 5,100 TRC employees being carbon neutral for All TRC employees’ household electricity consumption for TRC employees planting 103 212 145 years years million new trees 2020 TARGET Year-over-year growth in revenue from clean energy services 300 % 1 Growth in revenue from clean energy services 1: From FY16 to FY19 Between fiscal years 2016 and 2019 TRC increased revenue from clean energy services, including renewable energy, energy efficiency and energy storage by 300%. We have also supported the development of 129 solar projects that bring approximately 10,000 MW to market. 13
