Engineering and Construction Management GRDA chose Black & Veatch as its owner’s engineer to help develop bid strategy, prepare bid specifications, oversee technical negotiations, and perform follow-up construction management. Black & Veatch performed its role from inception to commissioning. The GRDA’s use of the M501J combustion turbine, built by Mitsubishi Hitachi Power Systems Americas, is a first in the western hemisphere. The J-series turbine has a thermal efficiency of more than 60 percent. The turbine is paired with a first-of-a-kind Nooter/Eriksen heat recovery steam generator (HRSG), that features a dual, high-pressure steam drum configuration to support high exhaust gas temperatures from the turbine. The generating facility adds to GRDA’s diverse energy portfolio that includes a variety of fuel sources to meet the needs of its customers. VIDEO: Advanced Class Combustion Turbine Technology × Overcoming Challenges The Grand River Dam Authority completed the Unit 3 project on time and on budget. The team built Unit 3 while simultaneously performing an air-quality control project on Unit 2, making the Grand River Energy Center an even cleaner source of energy. The agency made highly detailed construction planning a priority to overcome challenges. Due to flooding along the Mississippi River, delivery of the combustion turbine and steam turbine generators were delayed by several weeks. The team responded by quickly changing the sequence of critical path events, and it rescheduled the use of heavy lifting equipment and craft labor. Sound contingency planning allowed the team to conquer these challenges; however, nothing could have prepared it for the setback in July 2016. Lightning struck Unit 2 during peak construction on Unit 3. The resulting fire and destruction to Unit 2’s turbine and generator meant the team would have to rebuild that unit. It also set back construction on Unit 3 by several days. Although discouraging, the team didn’t let the additional adversity get in the way of its mission: to achieve and set a new standard for efficiency and reliability for power generation; and, to achieve the highest level of excellence in project design and execution through a commitment to quality, innovation and safety. It revised construction plans once again and picked up where it left off on Unit 3, bringing it to a successful completion. “The municipal customers are appreciative of what GRDA has done, and the initiative that they've taken to keep Oklahoma a great state by providing low-cost, reliable power,” said Mike Doublehead, General Manager, Tahlequah Public Works Authority. The project achieved more than 1 million man-hours without a recordable injury. In partial recognition, it received an award for “Excellence in Construction” from a chapter of the Associated Builders & Contractors, Inc.

Today’s wholesale markets are starting to push them in a different direction. Instead of load, utilities are being forced to follow their customers, and load doesn’t always come along with them. That’s leading to a wholesale market that’s becoming as decentralized and disaggregated as generation itself. The Business of Electricity: Will Distribution Markets Dominate? Imagine customers, third parties and perhaps even utilities participating in a market in which their investments in renewable energy and other forms of DERs could be monetized. The uptake of clean energy would dramatically accelerate, creating new opportunities for innovation and an open, inclusive energy economy. Energy as a Service: Power Without the ‘Plant’ When ride-hailing companies such as Uber and Lyft began disrupting the taxi business a decade ago, taxi operators scoffed and said consumers weren’t ready for such a radical approach to their entrenched business model. Finding the Right Power Generation Mix As ratepayers continue to seek more renewable energy integration, the electric industry is struggling to create the optimal mix of fuels that will economically meet sustainability goals. Boosted by a slew of factors – including decreasing costs, advancing technologies, new carbon-reduction policies, consumer pressure and regulatory support – renewables show no sign of slowing down. But their ability to provide reliable, consistent baseload power remains firmly in doubt because of the inherent intermittency of wind and solar photovoltaic. Distribution Planning: More Twists and Turns Ahead Planning for today’s distribution networks is a little like driving down a foggy road at night. Knowing what’s ahead and having more visibility makes a ride like that easier, but the clarity those two conditions provide is lacking for utilities and other players in the power sector as they travel toward a modernized grid.
