• The Value of Diversifying Uncertain Renewable Generation through the Transmission System – The Institute for Sustainable Energy at Boston University used ENELYTIX to study the value of transmission between markets as a function of renewable generation diversity and uncertainty.

    The study found that the benefits of adding transmission depend not only on the geographic diversity of renewables but also on the uncertainty between day-ahead and hour-ahead scheduling and real-time operations. Looking at penetration levels between 10% and 60%, reductions in real-time production cost from transmission additions are between 2 and 20 time higher than those in the day-ahead market.
  • Transmission To Capture Geographic Diversity of Renewables – The Brattle Group conducted a study to evaluate the benefit of transmission that interconnects two regions with high levels of renewable penetration. Two realistic, identical systems were constructed and analyzed under "disjointed" and "interconnected" operations. Enelytix was used to simulate unit commitment and dispatch on a day-ahead (DA), hour-ahead (HA), and real-time (RT) basis, including explicit simulations of spinning, regulation up and down, and intra-day commitment option (ICO) reserves. The ability to have simulation results from hundreds of scenarios using the cloud, enabled more in-depth analysis of outlier scenarios.

    The study found that "interconnected" operation resulted in production cost and reduced curtailment benefits even under modest levels of interconnection. More importantly, a major portion of the benefits were realized in RT operations and would be significantly understated using traditional DA only modeling.
  • Exploring Natural Gas and Renewables in ERCOT, Part III– The Texas Clean Energy Coalition commissioned a report to examine broad patterns of interaction between natural gas and renewable resources over the next twenty years.

    Enelytix was used to simulate both the market driven additions and retirements of capacity and the operation of the ERCOT system down to the intra-hour time frame. Combining the long and short term time frames was guided by the assumption that as the amount of renewable capacity grows, so does the relevance of short-term capabilities such as ramping capacity and quick start reserves. The report found that in the absence of continued or enhanced policy supports, natural gas generation would be the primary addition of choice though 2032, even with significant declines in the price of wind and solar power.
  • Rate Impact on LIPA Resident and Commercial Customers Of 250MW Offshore Wind Development on Eastern Long Island – TCR conducted a study to provide policy and decision makers with a context for evaluating the development and deployment of offshore wind off the coast of Long Island. The objective was to report the net of the benefits and the costs in terms of the bill impact on residential and commercial consumers on the island. Enelytix was used to evaluate a 250 MW off-shore wind farm and its impact on LMPs throughout LIPA and in turn to estimate impacts on residential and commercial electricity rates.
