At ENGIE, we have a safety-first policy that extends to every project we build. Our permitting and compliance process ensures that all local, state, and federal regulations are met and that the project will be suited to the local environment. Although it is extremely unlikely that a serious event will happen at the project site, we do have a comprehensive emergency management plan, which ensures that safety personnel are trained and able to respond appropriately.

Why Solar and Wind Energy?

Demand for wind and solar energy has grown dramatically over the past decade. Advances in these technologies have translated into falling costs, making them the least costly option for new generation facilities to meet the growing demand for electricity in many parts of the U.S. and Canada. Wind and solar energy are clean, affordable, domestic sources of power generation and important components of a secure energy future.

Where will the power generated from the projects go?

The power from the Empire Prairie Project will be delivered into the local Missouri electrical grid, helping to strengthen and diversify Missouri’s energy portfolio.

How do wind and solar projects make energy more affordable?

The Empire Prairie Project would help keep energy affordable by supplying low-cost clean energy to the power grid. Wind and solar power also have the benefit of producing electricity during the times of day when demand and power costs are the highest. On a mid-summer afternoon, for example, when homes and businesses are running air conditioners at full power, a solar facility is also generating electricity at full power, which helps close the gap between electricity supply and electricity demand. This has the effect of lowering electricity costs across the board.

Solar FAQs

What do solar projects look like?

Utility-scale solar projects are a collection of solar panels situated on posts or platforms above the ground at a low angle to collect the maximum amount of energy from the sun. Due to the natural vegetation and topography of the Empire Prairie Solar site, the project will be blended into the surrounding environment, allowing for maximum energy generation with minimal visual impact.

What is the ideal weather for solar projects?

Solar panels are able to function year round. Even on cloudy or snowy days, solar panels can continue generating electricity. Sunny cold weather is actually an ideal condition for solar panels to perform optimally. A light dusting of snow has little impact on the panels and can be easily blown off by the wind. Because panels track the path of the sun over the course of a day, snow will also slide off of panels over time, cleaning the panel as it melts and slides off. After heavier snowfall, panels will be cleared by facility employees.

How do solar panels contribute to a cleaner and safer environment?

By capturing solar energy through solar panels, we are able to generate clean energy that does not produce any greenhouse gases or pollution. Solar energy gives us a safer, more environmentally friendly alternative to traditional forms of energy generation while diversifying our grid to prevent power shortages. In today’s modern era, we have an ever-increasing need for reliable, affordable power. Luckily, the energy from the sun is the most abundant energy source on the planet! The Empire Prairie Solar project will generate clean energy needed to secure a safe and energized future for Northwestern Missouri.

What are the benefits of solar energy?

Solar energy projects bring a multitude of benefits to the communities in which they are situated. These projects have a significant positive impact on the local economy due to the infusion of millions of new dollars of tax revenue. This tax revenue enables improvements to local schools, infrastructure, and public services.

Solar energy projects provide energy security and prevent power shortages that cause brownouts and blackouts. This source of energy diversifies the grid, allowing consumers to enjoy more affordable, reliable, domestic energy without interruption.

Landowners also enjoy benefits from participating in solar projects. By leasing a portion of their land, they are able to receive lease payments that help diversify their in come and protect their land for future generations.

Last but not least, solar energy projects contribute to cleaner air and water in the region by contributing energy that does not produce any greenhouse gases or pollution.

Solar energy provides reliable, long-term benefits for communities, landowners, and the environment. By generating electricity from the sun, solar projects reduce dependence on foreign fuels, lower greenhouse gas emissions, and help stabilize energy costs. They also create local jobs during construction, generate steady tax revenue to support schools and public services, and provide landowners with consistent lease income. With minimal water use and quiet operation, solar is one of the cleanest and most sustainable energy sources available today.
‍

What happens to solar panels at the end of their lives?

Every ENGIE project is accompanied by a decommissioning plan that is funded by an irrevocable form of financial security. At the end of a solar facility’s useful life, estimated to be about 30-35 years on average, panels can be removed and recycled. Recycling programs are being developed that are expected to recover about 90% of the materials used in the panels, much of which is glass.

Wind FAQs

What do wind turbines look like?

Wind turbines stand sleek and tall on the horizon while having a small footprint on land. This small footprint enables farming to continue while providing a weather-proof source of income. We carefully consider setback boundaries as we design every project and have the utmost consideration for our landowners throughout the process.

Wind turbines contain impressive internal equipment that allows for the collection and transmission of electricity. Modern wind turbines are also equipped with Aircraft Detection Lighting Systems (ADLS), which notify nearby aircraft of their presence. The red flashing lights on wind turbines at night are to signal to aircraft that there are turbines ahead. ADLS can be programmed to flash only briefly when an aircraft approaching.

What is the ideal weather for wind projects?

Wind turbines are able to function year-round. Due to their altitude and thoughtful placement based on wind resources, wind turbines are able to capture wind even on calmer days. Wind, direction, speed, and strength are constantly changing, which explains why some turbines rotate while others remain idle. Wind turbines are also able to be engineered for cold climates and can function properly at temperatures all the way down to-22° Fahrenheit

What are the benefits of wind energy?

Wind energy is able to provide a stable, domestic supply of electricity, bringing communities greater energy independence and more affordable energy prices. The Empire Prairie Wind Project will be located on sites chosen expressly for their excellent wind resources. This will allow up to 400MW of wind energy to be collected and distributed to the grid. Diversifying our energy sources will strengthen local communities and infuse millions of dollars of new tax revenue into the region.

Landowners benefit from wind projects by leasing their land for steady lease payments, diversifying their income, and preserving their land for future generations.

Wind energy also promotes cleaner air and water by generating power without greenhouse gases or pollution.

What happens to wind turbines at the end of their lives?

At the end of a wind turbine’s useful life—estimated to be about 20-25 years on average—the turbine is disassembled by removing the blades, tower, foundation, and other components. The site is restored to its original condition, and most parts are able to be recycled. In fact, around 96% of a wind turbine is made from recyclable material that can be re-used in the manufacturing of metals, plastics and glass. Every ENGIE project is accompanied by a decommissioning plan that is funded by an irrevocable form of financial security to cover decommissioning costs.

Battery Storage FAQs

What is battery energy storage?

Battery energy storage is a technology that stores electricity so it can be used later. A battery energy storage system, sometimes called a BESS, charges when electricity is plentiful, stores energy, and then releases it back to the grid when it's needed most. Think of it as an energy reservoir that can be tapped when the grid needs it, helping to meet increased demand.

How does battery storage work?

A battery storage facility is made up of banks of rechargeable batteries housed inside sealed steel enclosures. When there's more electricity available than the grid needs, the system draws power in and stores it. When demand rises, the system discharges stored energy back to the grid. A control system manages the charging and discharging automatically, responding to grid conditions in a fraction of a second.

How does battery storage make energy more reliable?

Energy demand rises and falls throughout the day, peaking on hot summer afternoons and cold winter mornings. Battery storage helps close the gap between energy generation and energy need, storing power during low-demand hours and delivering it during peak hours, increasing supply during periods of highest demand to better manage costs.
‍

Because batteries respond almost instantly, they also help stabilize the grid during unexpected disruptions, such as when a power plant goes offline or demand spikes suddenly. This helps prevent the kinds of supply shortfalls that cause brownouts and blackouts, and reduces the price spikes that come with them.

What do battery storage projects look like?

A battery storage facility is a fenced area containing rows of sealed steel enclosures roughly the size of shipping containers, along with equipment that converts the stored electricity so it can be distributed to the grid. The facilities are generally sited adjacent to already existing electric substations and power lines, and fit within a compact footprint. The battery containers are low to the ground, typically well under the height of a home, and have no moving parts.

Are these batteries safe?

Utility-scale battery storage commonly uses lithium-iron-phosphate batteries, or LFP, a chemistry chosen specifically for its thermal stability. It is a different formulation from the batteries used in most phones and electric vehicles, and is widely recognized as one of the safer lithium-ion chemistries available. Each installation also includes a battery management system that continuously monitors temperature, voltage, and performance, along with thermal management (to keep the batteries in their ideal operating range) and fire detection equipment.
‍

These systems are built and tested to nationally recognized safety standards, including UL 9540 for energy storage equipment and NFPA 855, the National Fire Protection Association's standard for energy storage installations. Batteries are spaced apart, so that an issue in one unit stays contained and isolated from the others.

Safe long-term operations of storage facilities are a priority for ENGIE. We work closely with local fire safety professionals throughout the design, siting and permitting processes to ensure years of safe operations for the storage facility and surrounding community.

Are battery storage facilities noisy?

Battery storage has no engines, turbines, or other large moving parts. The main sources of sound are the cooling systems that regulate battery temperature and the equipment that converts power for the grid. These run intermittently rather than continuously, and sound levels fall off quickly with distance. Manufacturer testing and sound certifications are within acceptable decibel ranges and usually meet any local sound ordinance.

Do battery storage facilities produce emissions or use water?

Battery storage facilities produce no emissions while operating, and they require no water to operate. Cooling is handled by air or by a sealed liquid loop that circulates the same coolant continuously rather than drawing new water. Enclosures also include built-in spill prevention and stormwater controls to protect local water flows and groundwater in the event of an incident.

How long do batteries last?

A utility-scale battery storage facility has a typical operating life of at least 20 years. Like any battery, capacity gradually declines with use, and individual units are monitored and may be replaced over time to maintain the system's performance.

What happens to batteries at the end of their lives?

Batteries that no longer meet the performance needs of a utility-scale facility often still hold significant capacity, so they can be repurposed for less demanding applications, an approach known as giving batteries a "second life."
‍

Beyond reuse, batteries contain valuable materials, including lithium, iron, phosphate, and copper that can be recovered. LFP batteries contain no cobalt or nickel and no toxic heavy metals. Because large-scale battery storage is a relatively new industry, recycling infrastructure is still developing, but it is expanding quickly as demand grows and as more systems approach end of life.

Why is battery storage being added to wind and solar projects?

Wind and solar generate electricity when the wind blows and the sun shines, which doesn't always line up with when demand is highest. Pairing energy generation with storage means energy produced at midday or overnight can be saved and delivered during peak hours instead of going unused. This makes the overall project more useful to the grid and helps deliver steady, dependable power from renewable sources.
