Renewable Energy and Battery Storage: Building More Efficient and Resilient Businesses

Renewable energy and battery storage are becoming important tools for businesses looking to manage energy costs, improve reliability, and reduce their environmental impact. But installing solar panels or batteries is not automatically the right solution for every facility.

The real opportunity comes from understanding how energy is used, when it is needed, and which technologies make the most sense for the operation.

Why Renewable Energy Matters

Businesses depend on reliable electricity to operate buildings, equipment, computers, manufacturing processes, and other essential systems. As energy costs and demand change, organizations are looking for ways to better manage their electricity consumption.

Renewable energy technologies offer alternatives to conventional grid electricity. Common options include:

● Solar photovoltaic (PV): Converts sunlight into electricity and can be installed on rooftops, parking structures, or available land.

● Wind power: Uses wind turbines to generate electricity where conditions and site characteristics are suitable.

● Geothermal energy: Uses heat from the earth, particularly for heating and cooling applications.

● Hydropower and biomass: Provide additional renewable energy options depending on location and available resources.

The best choice depends on the facility, energy requirements, available space, local conditions, and project economics.

The Role of Battery Storage

Battery energy storage systems allow organizations to store electricity and use it when needed.

For example, a facility with solar panels may generate more electricity during the day than it immediately consumes. A battery can store some of that excess energy for use later, including during periods when electricity prices are higher or solar production is lower.

Battery storage may also help organizations:

● Reduce peak electricity demand.

● Manage time-of-use electricity rates.

● Support critical loads during certain power interruptions.

● Improve the use of onsite renewable generation.

● Provide additional flexibility in managing electricity consumption.

However, battery systems require careful planning. Capacity, operating strategy, installation costs, maintenance, and expected savings all need to be evaluated.

Combining Renewables and Storage

Renewable generation and battery storage can work together as part of a broader energy management strategy.

A commercial building, for example, might use rooftop solar to generate electricity during daylight hours while a battery stores excess production. The facility can then use stored electricity during evening operations or selected periods of high demand.

Some organizations may also consider a microgrid, which combines onsite generation, storage, controls, and selected electrical loads. Depending on its design, a microgrid can operate alongside the utility grid and may provide limited independent operation during an outage.

These systems are particularly worth evaluating for facilities where continuity of operations is important.

Does the Investment Make Financial Sense?

Before moving forward, organizations should evaluate the financial and operational benefits.

Important considerations include:

● Current electricity costs and demand charges.

● Facility energy consumption patterns.

● Available space and renewable energy resources.

● Equipment, installation, and maintenance costs.

● Expected energy savings and battery operating benefits.

● Utility programs, incentives, and applicable financing options.

Financial tools such as simple payback, net present value (NPV), and internal rate of return (IRR) can help compare alternatives.

It is also important to remember that the lowest-cost system is not necessarily the best investment. Reliability, equipment life, operating requirements, and future energy needs should be part of the decision.

Start With an Energy Assessment

Organizations do not need to begin with a major renewable energy installation. A practical first step is understanding how the facility uses energy.

Review utility bills, identify peak demand periods, evaluate major energy-consuming equipment, and determine whether the building has suitable conditions for renewable generation or storage.

From there, energy professionals can compare options and develop a project that supports both financial and operational goals.

Building the Knowledge to Make Better Decisions

Renewable energy and battery storage involve more than selecting equipment. Successful projects require an understanding of energy fundamentals, electrical systems, technology options, and financial feasibility.

PBJ Tech Hub offers professional development through its course, Top Proven Renewable Energy and Energy Storage Technologies. The course examines renewable energy alternatives, energy storage technologies, technical considerations, and financial feasibility.

The goal is simple: help energy and facility professionals make better-informed decisions about the technologies that may shape their organizations’ energy future.
