The Brattle Group conducted a study of the potential economic benefits of energy storage in California under a contract with Eos through funding from the California Energy Commission.
Enelytix was used to We assess battery storage value under a broad range of California-specific market conditions and system costs observed between 2013 and 2016. The study
accounted for the value of avoided energy, generation capacity (i.e., resource adequacy), transmission and distribution capacity, and ancillary services.
The study found that in many cases, the “stacked” benefits of battery storage compare favorably to recent estimates of new battery costs.

As projections for the installed cost of battery systems is dropping, Oncor Electric Delivery Company wanted to explore the economics of grid integrated storage deployment in Texas.
Enelytix was used to calculate expected realized system costs and wholesale energy and ancillary-service revenues under various weather conditions.
The study found that while there
were significant benefits from storage deployment, storage investments could not be undertaken at an efficient scale solely by merchant developers in the Texas wholesale market.

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.

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. Read the full report here.
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. View the report
A study that describes best practices and lessons learned from efficient and reliable integration of renewables for the Carribean island systems. Enelytix was used to study the operational flexibility of wind,
solar, battery and flywheel technologies. Simulations were performed to evaluate the impacts on regulation needs, system flexibility to accomodate renewable ramps, contingency events, minimum thermal generation
requirements and renewable curtailments. In small island systems, operational dynamics have a significant impact on planning decisions and Enelytix was the primary tool used to explicitly value these dynamics.
