This paper presents a sizing methodology and optimal operating strategy for a battery energy storage system (BESS) to provide a peak load shaving. The sizing methodology is used to maximize a customer's economic benefit by reducing the power demand payment with a BESS of a minimum capacity, i.e. a system with a lowest cost.
The storage of electricity for the purpose of peak demand shaving is receiving great interest, with numerous pilot projects being conducted in several countries . Such demand management is important to electricity utilities as additional non-dispatchable generators, such as wind turbines, are installed .
Such distributed thermal energy storage, located within buildings or communities, poses one solution to such issues by providing a means to store electricity during off-peak and/or high renewable electricity generation times, and utilize this stored energy when peak electricity demand occurs.
The next generation of distributed energy storage will absorb and release electricity so that it is suitable for all end-uses, including space cooling, appliances, and lighting, as well as allowing for bi-directional electricity transfer with the utility for added grid support functionality.
Therefore, a 5 kWh lithium-ion battery pack will occupy approximately 30 L volume (0.03 m 3) and can easily and safely fit in a small cabinet along with a 3000–5000 W inverter for installation in a mechanical room or basement location.
Examples of electricity demand peaks and wind power generation are shown in Fig. 1 for the Canadian province of Ontario, which experiences one daily demand peak in winter and two in summer. It is apparent from Fig. 1 that wind power generation experiences large and rapid output variations that are unrelated to changes in electricity demand.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
Technological advancements are dramatically improving home solar storage and inverter performance while reducing costs. Next-generation battery management systems maintain optimal performance with 40% less energy loss, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $1,200/kW to $650/kW since 2022. Smart integration features now allow home systems to operate as virtual power plants, increasing homeowner savings by 35% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 25% for solar storage installations. New modular designs enable capacity expansion through simple battery additions at just $600/kWh for incremental storage. These innovations have improved ROI significantly, with residential projects typically achieving payback in 5-8 years depending on local electricity rates and incentive programs. Recent pricing trends show standard home systems (5-10kWh) starting at $8,000 and premium systems (15-20kWh) from $12,000, with financing options available for homeowners.
