Clean, Efficient and Resilient Energy Systems Technology cost reductions are leading to rapid growth in variable renewable sources of generation, requiring the electrical grid to be structured and operated differ- ently 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 fiscal year 2018 TRC increased revenue from clean energy services, including renewable energy, energy efficiency and energy storage by 81% and supported the development of 7,000 MW of wind and solar projects In one year, our Energy Efficiency group managed projects that saved 3 billion kilowatt-hours. That’s equivalent to… All 5,000 TRC employees being carbon neutral for 37 YEARS All TRC employees’ household electricity consumption for 77 2020 TARGET YEARS Year-over-year growth in revenue from clean energy services TRC employees planting 79 MILLION NEW TREES 81 % Year-over-year growth in revenue from clean energy services 13
