INDUSTRIAL AND COMMERCIAL SOLUTION

Generate Consistent, Reliable On-Site Power

Threatened by both the potential of energy price increases and the risk of energy reliability, large power consumers can often make a sound business case for taking a more independent posture when it comes to energy. Some invest in on-site generation resources, some opt for large uninterruptible power source (UPS) systems to guard against the loss of power during a blackout, while others choose to detach from the grid all together. The largest consumers and those with mission critical needs are focusing more attention and resources on integrating solar and energy storage options, as both economic and environmental pressures grow.

UTILITY SOLUTION

Deliver Large Scale Renewable Energy & Optimize Utilize Transmission Network

As growing urban areas demand more electricity and aging generators are retired due to environmental or economic reasons, transmission congestion is a growing problem. This congestion limits the supply of energy that can be delivered to pockets of high demand and forces Grid Operators to pay high wholesale energy prices. Relieving this congestion requires capital intensive transmission and distribution infrastructure upgrades that involve a complex and onerous project planning process requiring extensive permits, strict siting limitations and prolonged lead times. Adding to these difficulties, T&D upgrades are often oversized to cover uncertainty of future demand which is an inefficient and costly way to add capacity.

Clean Sky Energy’s integrated Solar, sub-station and energy storage solution offer a reliable and economic solution to increase electricity production and decrease transmission congestion by efficiently increasing the load carrying capacity of current T&D infrastructure and providing energy locally when delivery is constrained. The Clean Sky Energy integrated solution can provide significant capacity to defer or replace oversized T&D upgrade investments while simplifying project logistics with easy permitting, minimal siting restrictions, and shorter project lead times for new electricity generation.

WHY SOLAR ENERGY

While a majority of the world’s current electricity supply is generated from fossil fuels such as coal, oil and natural gas, these traditional energy sources face a number of challenges including rising prices, security concerns over dependence on imports from a limited number of countries which have significant fossil fuel supplies, and growing environmental concerns over the climate change risks associated with power generation using fossil fuels. As a result of these and other challenges facing traditional energy sources, governments, businesses and consumers are increasingly supporting the development of alternative energy sources and new technologies for electricity generation.

As a result of these and other challenges facing traditional energy sources, governments, businesses and consumers are increasingly supporting the development of alternative energy sources and new technologies for electricity generation:

  • Reduced Dependence on Fossil Fuels:    Solar energy production does not require fossil fuels and is therefore less dependent on this limited and expensive natural resource. Although there is variability in the amount and timing of sunlight over the day, season and year, a properly sized and configured system can be designed to be highly reliable while providing long-term, fixed price electricity supply.
  • Environmental Advantages:    Solar power production generates electricity with a limited impact on the environment as compared to other forms of electricity production.
  • Matching Peak Time Output with Peak Time Demand:    Solar energy can effectively supplement electricity supply from an electricity transmission grid, such as when electricity demand peaks in the summer
  • Modularity and Scalability:   As the size and generating capacity of a solar system are a function of the number of solar modules installed, applications of solar technology are readily scalable and versatile.
  • Flexible Locations:    Solar power production facilities can be installed at the customer site which reduces required investments in production and transportation infrastructure.

WHY ENERGY STORAGE

Grid Energy Storage is a vital and integral component of Clean Sky Energy’s renewable energy and energy storage solution. We know that energy created from solar is variable by nature as the amount of electrical energy produced varies with time, day of the week, season, and weather. In an electrical power grid without energy storage, energy sources that rely on energy stored within fuels (coal, oil, gas) must be scaled up and down to match the rise and fall of energy production from intermittent energy sources.  This has always proved to be a challenge with many utilities deploying large scale solar projects.

The use of an energy storage system coupled with advanced power electronics and controls to maintain electric grid stability during brief power system variations and momentary power interruptions helps mitigate the challenges concerning voltage, frequency, and power quality, as well as power supply during unfavorable weather conditions.

In both, on-grid and off-grid microgrids, the use of energy storage enable an economic, efficient, and environmentally sound energy management practice.

Matching electricity generation and demand to maintain stability is the main goal of the electric power system. Whether you are a customer, a generator or the utility, making sure that the “lights stay on” is paramount. Clean Sky Energy’s renewable energy and energy storage solution enables community residential, industrial and utility clients to do just that; generate and maintain a reliable and predictable electrical micro-power grid.

The electric grid is the premier example of just-in-time delivery, as the grid must be continually balanced to ensure that just enough electricity is being generated to maintain the required voltage and frequency stability. Maintaining this balance is incredibly challenging, as customer energy needs are continually changing.

Energy storage devices can act like a warehouse for the grid, allowing us to manage the expected ebb and flow of demand throughout the day. They can also act like shock absorbers, making intermittency of either supply or demand easier to handle.

Today “storage” is already present, but it mainly appears as an excess of capacity in generation, distribution and transmission. This excess capacity is expensive and inefficient. New energy storage technologies, utilizing decades of advancements in battery technology are making electricity storage the more cost effective and reliable answer

When discussing the integration of renewable energy sources like solar onto the grid; variability of generation is the challenge in areas with remote grids, high levels of renewable penetration, or critical loads. Energy storage systems enable greater integration of renewables onto the electric grid by smoothing and time-shifting that renewable power. With an integrated storage solution in place, power producers can benefit from firm, dispatchable power, as well as increased revenue.

Storage for solar: Storage can work with solar photovoltaics (PV) to create a smoother output signal, which also more closely aligns with the peaks in electricity demand. Clouds can cause dramatic dips in electricity output, as much as 80% of peak output in under 1 minute, followed by equally dramatic increases after the clouds pass by. Storage can work to mitigate these events by discharging during the cloud period to more slowly ramp the system down, in a way that causes less grid disturbance. In addition, through the act of smoothing, energy can be saved for later in the evening to push the solar back a few hours to better align with demand use peaks.

Clean Sky Energy’s storage products are fast-acting, highly efficient energy storage systems, and when integrated with a dependable solar component, allow Power Generators to reliably meet peak demands of the energy market without the start-up costs, minimum run times, and high fuel costs associated with traditional generation resources.

RENEWABLE TECHNOLOGY INTEGRATION

Power purchasers now demand that renewable generators, namely wind and solar, mimic traditional fossil-fuel generation by requesting them to provide smoother power, dynamic VAR compensation, and firm day-ahead schedules, among other things. Solar Renewable Developers gain considerable value from the integrated storage technology, whether it be from higher Power Purchase Agreement prices for firmer power, having the opportunity to participate in lucrative Ancillary Services Markets, taking advantage of energy arbitrage opportunities, a reduction of balancing costs, or a combination of services.

The main services for Renewable Integration are:

Ramp Control and Smoothing
The energy storage management software monitors output from the generation source (solar) on a microsecond basis and automatically responds by either absorbing generator output or supplying energy storage output so that the grid receives smooth, clean power at a desired MW/minute rate.

Responsive Reserves
The unique sizing scheme of the energy storage management system allows the customer to add more energy storage (MWh) and act as a responsive supply resource for prolonged periods of time via Automatic Generation Control (AGC). In doing so, not only will a greater amount of renewable energy be delivered to the grid, but emissions from fossil generation will be reduced.

Frequency Response (Primary Control)
Like generator droop response and turbine-generator rotating inertia, the energy storage systems management software can actively correct frequency deviations automatically in real time with power injections and withdraws following major electrical disturbances, as well as address less severe frequency deviations due to normal grid operations throughout the course of each day.

Firming/Shaping
Coupling a energy storage solution with a renewable generation forecast allows the customer to organize other generation resources to meet expected demand based on its guaranteed day-ahead output schedules, as well as reshape output to deliver power during peak demand times regardless if the renewable asset is generating power or not. If a forecast is inaccurate, the energy storage management system automatically supplies or absorbs power on a microsecond basis to ensure the day-ahead output schedule is met.

ENERGY STORAGE SYSTEM APPLICATIONS

Energy storage system applications are classified according to power, energy capacity, usage time, etc. Applications include megawatt-scale power storage for frequency regulations, large capacity energy storage (MWh scale) for peak time demand response.

Frequency Regulation / Spinning Reserve
Frequency regulation uses reserved energy to supply electric power at a specific frequency that matches the frequency difference between power plants or substations. Through frequency regulation, the quality and reliability of power systems can be greatly improved. If there is a problem with the power system, frequency regulation responds to the problem first (10 s~15 min), and the spinning reserve responds next (10 s~15 min).

Peak Shifting (Peak Shaving)
Peak shifting is the ability to minimize the burden on power plants by controlling peak demand, smoothing the output of renewable energy, and dispersing usage time. Power is saved in the energy storage system (ESS) when power generation is sufficiently high. During peak usage time, power stored in the ESS is used. In addition, peak shifting ESS can be categorized according to the usage time of two of its applications: (1) When peak shifting occurs only during peak usage, for about 1~2 hours, and (2) When load leveling is required for long-term usage, for about 5~6 hours, regardless of the peak time. By using a peak shifting ESS, energy efficiency is enhanced by reducing the burden on the power plant during peak daytime hours.
