Everything truly is bigger in Texas, including the installation of Duke Energy’s wind energy storage system. With a 36MW energy storage and power management system installed at the Notrees Wind project, the Duke Energy system regulates and optimizes the delivery of energy. Using Xtreme Power’s Powercell™ battery, the storage system addresses the intermittency issues of the Notrees Wind project while using a battery made of non-hazardous, recyclable materials. In addition to being the largest wind connected project in North America, this project was instrumental in changing the paradigm for energy storage in Texas. As the first project of its size in TX, much like the earlier pioneering projects in PJM, it expanded the horizon for interconnection requirements, and was instrumental in creating the fast responding regulation service pilot in ERCOT. Thus the project had major impacts in both demonstrating the technology at scale, but also important policy and regulatory impacts in TX, opening a new market for energy storage. Finally, the project was partially funded by DOE, demonstrating success as a key public-private partnership to move the storage market forward.

The Southern California Public Power Authority (SCPPA) has entered into an agreement with Ice Energy to purchase up to 53MW of peak load shifting (PLS) capacity with the installation of Ice Bear Thermal Energy Storage (TES) equipment on behalf of SCPPA's 12 publicly owned utility members as well as other municipal utilities (participants) in the region.
 
This could be the largest deployment of Ice Bears and provides participants an ability to achieve Utility-scale peak demand reduction and shifting of air conditioner load, while also providing valued efficiency improvements for individual commercial and industrial (C/I) customers - without sacrificing customer comfort. To date, 7 members and 2 other POUs have installed approximately 2.5MW of TES capacity in more than 200 customer's facilities.
 
These installations have provided participants new opportunities to work with C/I customers in partnership to help them cost-effectively reduce peak demand and shift energy usage to the off-peak period. In addition, the SCPPA agreement with Ice Energy requires that local engineers and HVAC contractors be used for the design and installation processes and that supplies and materials be acquired locally, to the greatest extent possible to provide local and regional economic development opportunities in the communities served by the participants.

In an effort to significantly reduce the usage of diesel fuel for power generation in Kodiak, Alaska, Kodiak Electric Association (KEA) developed a wind project to generate approximately 20% of the system’s annual power needs. The remaining 80% is generated with hydroelectric power, which was already an existing infrastructure. After modeling KEA's system, it was obvious that KEA's grid could not support the variation of 9 MW's of wind power without some type of energy storage. After examination of different solutions, the XTREME Power package was chosen. The installation of the wind turbines and BESS system took place in the fall of 2012. The system has preformed wonderfully. The BESS system operates over 200 times a day to system frequency issues. It is set up in droop mode and has saved the system from many frequency issues.

Starting in 2010, three energy industry partners (Duke Energy, FIAMM, and S&C Electric Company) came together to solve a problem that Duke Energy was beginning to experience on distribution circuits (12 kV – 24 kV) that have a high penetration of distributed solar generation.  Due to passing clouds, solar energy output was observed to rapidly fluctuate; cases were observed where over 80% of a solar unit’s output would drop in less than five seconds.  This rapid fluctuation in circuit power flows can cause undesirable voltage conditions that are difficult for existing infrastructure to correct.  To solve this, a battery system was envisioned that charged and discharged to absorb the solar-induced “power swings”, allowing the circuit’s voltage profile to remain smooth despite significant and rapid changes to the power flows along it.

Glenwood Management quickly understood the economic benefits of distributed energy storage.  Glenwood, the owner of high-end luxury apartments across New York City, has been working with Demand Energy to utilize the transactive energy market that has resulted from deregulation in New York. In this regard, Glenwood is a leader in the use of intelligent energy storage on the customer side of the meter to benefit both themselves and the various grid operators. Demand Energy's cloud based solution manages The Barclay Towers house load in real time, and incorporates the NYISO day-ahead pricing and using this information to direct the operational performance modes of the storage system from limiting the building's demand peaks during operational hours or time shifting a block of energy during a period of high hourly pricing. When the grid is strained by air-conditioning load in the summer, Demand Energy’s Joule system shifts operating modes to respond automatically to demand response events from NYISO’s and Con Ed, delivering value to the grid operators with no impact to tenant livability in the building.  If the Barlcay Tower faces another extended outage like what occurred during Hurricane Sandy, the critical power support from the Joule.System will supply power to circuits that supply water, emergency lighting and the service elevator. Intelligent Energy Storage helps Glenwood Management derive multiple benefits from this unique installation.

The comfort cooling system at the 1500 Walnut Street building was outdated and inefficient.  The system was replaced by a significantly more efficient system using a downsized chiller and ice thermal energy storage.  The storage shifted about 1/3 of the peak cooling demand and was justified by reduced demand charges.
 
Then the rates changed when the electricity market was deregulated.  The energy storage enabled the building owner to negotiate better energy rates due to the improved electrical load profile of the building.  However, demand charges were reduced when price caps were removed from the deregulated market prices.  This eliminated much of the demand related cost savings that resulted from shifting a portion of the cooling load.  The cooling system required a revised approach to operation in order to achieve the savings originally projected.
 
Tozour Energy and Viridity teamed with the building owner to modify the system for the new electric rate structure.  It was updated to operate optimally as a virtual generator by changing the controls to focus on the entire building electrical systems, including the IceBank energy storage.  The building now can react to day ahead pricing signals and is able to transparently shed load upon a call from the electrical grid (PJM).  1500 Walnut currently participates in the PJM Capacity Market and also the PJM Economic Energy Market. Viridity thinks that, dependent on the equipment responsiveness and controllability of 1500 Walnut, Viridity could consider them for PJM Ancillary markets – Synch Reserve and/or Regulation – in upcoming contracts.

Predictive analytics, big data, and luxury hotels? At first glance, one of these things is not like the other. However, InterContinental Hotels in San Francisco leveraged computing technology with energy storage to cut costs and still offer their guests the comfortable stay they expect from the hotels. InterContinental had difficulty managing high demand charges due to load spikes, so they installed a Stem system to leverage predictive analytics and big data with energy storage. The combination allowed InterContinental to “hybridize” the hotels and effectively switch between battery and grid power to manage energy costs. The installation was so successful that it is being rolled out to all 16 of the California-based InterContinental hotels and has a projected savings of $2.2 million over the next ten years. Dreams of a greener hotel have now become a reality - so sit back, relax, and enjoy your stay!
