System Operators and Utilities

Modern electricity grids are expected to efficiently deliver reliable energy to customers. From managing growing demand to supporting the integration of renewable technologies, system operators and utilities must be at the forefront of technological innovation to ensure ratepayers receive premium service.

Improve System Flexibility with Energy Storage

Energy storage technologies are highly flexible and allow system operators and utilities to better manage the power system. With the ability to act as both load and generation, energy storage can ensure that existing infrastructure is fully utilized and scheduled generation can be efficiently used to meet forecast demand.

 


Load Leveling can optimize the production and operation of the grid's existing resources. Electricity can be stored and injected back into the grid when necessary. This can reduce inefficient peaking generation from traditional fossil fuel generation, enable renewable generation and allow nuclear generators to maximize output.

Make the most out of your existing generation assets

Load Leveling encompasses a variety of services that  include:

  • Energy Arbitrage: Purchasing electricity at low demand and low price periods to store and later resell during high demand and high price periods
  • Wind Integration:  Matching actual intermittent generation to scheduled generation
  • Dispatchable Wind: Providing baseload or constant wind generation
  • Peak shaving: Reducing large end users' individual peak consumption periods to lower electricity bills

Ancillary services like frequency regulation are essential to the reliable transmission of energy across electricity grids. NRStor’s 2MW Minto Flywheel System will deliver frequency regulation service in 2014. Fast responding energy storage technologies can react almost instantly to withdraw or inject electricity in response to changes in system frequency.

Ramping services enable generation assets to increase their electricity production quickly over a short period of time. As both generation and demand fluctuate throughout the day, fast responding resources are needed to ensure system balance. Energy storage technologies are highly flexible and capable of quickly responding to generation command signals. Energy storage resources typically have incredibly high ramp rates, in many cases hundreds of times faster than the ramp rates achievable with traditional generation.

In the past, traditional solutions to address peak electricity load growth typically included costly system upgrades such as new generation, substation retrofits or new poles and wires. Today, energy storage provides an alternative to traditional resource planning. By optimizing your existing assets, storage can defer the need for large investments in generation, transmission, and distribution infrastructure.

Power quality issues can lead to prolonged outages and facility downtime, damaged equipment, and significant annual costs.

To stabilize voltage sags and improve power quality, an uninterruptible power supply (UPS) system provides emergency power and ride through capabilities to your system. Typically, UPS systems provide up to 60 seconds of energy storage.

Protect your equipment from damage caused by power disruptions

During a momentary power quality issue, the energy stored in a UPS system automatically provides near instantaneous protection allowing you to ride through disturbances, give you time to safely shut off equipment or start a longer term backup power source.
