Dr. Celebi provides expertise in electricity markets and the analysis of environmental and climate policy.

He has testified and consulted primarily in the areas of electricity spot pricing and market design, and has experience in developing and analyzing climate policies, LMP modeling, generation plant valuation, and competitive implications of mergers.

Dr. Celebi wrote his Ph.D. thesis on the analysis of incentives and regulation to provide transmission capacity in deregulated electricity markets. His recent engagements include estimating economic damages in energy contracts, valuations of coal-fired and gas-fired power plants, impacts of environmental regulations on power markets, cost/benefit assessment of RTO membership to electric utilities, and nodal pricing simulations in the U.S. electric markets. He has provided testimony in regulatory cases involving the impact of coal plant retirements on wholesale energy prices, LMP simulations in PJM, and allocation of certain ancillary services costs among market participants in ERCOT.

Dr. Celebi is a frequent speaker at energy conferences on topics such as coal plant retirements and environmental policies.

Representative Engagements
Cost/benefit assessment of joining RTOs
For a group of electric utilities in the Midwest, led a team to assess the energy-related costs and benefits of joining an RTO. Using a nodal pricing simulation software, the team estimated the net costs to customers of the utilities with respect to energy, congestion, marginal losses, and allocation of financial transmission rights and loss refunds under each configuration (stand-alone and RTO membership).
Sale advisor for a coal-fired generation plant
Co-led a team to assist a municipal electric utility in the Midwest to sell a portion of its share of energy and capacity from a new coal plant. The team acted as the Sale Advisor to design the sale process, solicit bids, prepare informational documents, and evaluate the bids.
Supply-chain implications of environmental retrofits in MISO
Co-authored a study commissioned by the MISO to evaluate the feasibility of the large number of simultaneous environmental retrofits and new generation that may be needed for coal plants to comply with the EPA’s Mercury and Air Toxics Standards (MATS) rule.
Energy contract litigation support
For a group of municipal electric utilities in Massachusetts buying energy from a generating facility under a long-term contract, assisted in evaluating their net benefits from requesting must-run operation of the facility relative to the operations chosen by the seller.
Expert testimony on long-term contracts
In a large litigation case before FERC, provided testimony on the economic burden imposed by the prices in two long-term contracts that California Department of Water Resources (CDWR) signed with Shell and Iberdrola during the California energy crisis. Estimated the “down the line” economic burden by comparing the payments under the contracts to prices in comparable contracts and market prices after the end of the dysfunction. Assessed whether the contract prices could be explained by the expected future market fundamentals in the California power markets by using DAYZER market simulation software for the near-term and expected cost of installing and operating a new generation unit for the long-term.
Expert testimony on market impacts of coal plant retirements
For Wisconsin Public Service Corporation, provided expert testimony on the likely changes in energy and capacity prices as a result of projected coal plant retirements and environmental retrofits in the MISO region.
