Smart EMS Enabling Prosumer Efficiency with Solar and Storage

Updated: 2 hours ago

As the energy landscape rapidly evolves, prosumers - individuals or businesses that both produce and consume energy, often through solar Photovoltaic (PV) systems combined with Electricity Storage (ESS) - are playing a pivotal role in building a sustainable future. For prosumers, effective energy management is essential for maximizing savings, minimizing grid dependence, and advancing decarbonization goals. Central to this effort is a robust Energy Management System (EMS), which integrates advanced forecasting, automation, and energy storage control to ensure seamless operation and peak efficiency.


Energy management can be visualized as a pyramid, with three critical pillars and corners at its base: forecasting energy generation, forecasting consumption, and predicting grid prices. At the apex of this pyramid is the EMS, functioning as the intelligent orchestrator, while the core of the system lies in the battery energy storage system (BESS), which dynamically balances supply and demand in real time.

Forecasting: The Foundation of Smart Energy Management

For prosumers, accurate forecasting is essential to managing energy flows effectively. Generation forecasting focuses on predicting solar output, leveraging weather data, historical trends, and seasonal patterns. This enables prosumers to anticipate how much energy their PV systems will produce and plan accordingly to maximize its use.


Consumption forecasting, on the other hand, provides insights into energy demand patterns. It factors in typical household or facility usage, additional loads such as electric vehicle (EV) charging, and opportunities to adjust energy use based on time-of-use pricing. By aligning consumption with generation, prosumers can reduce reliance on the grid and optimize energy efficiency.


The final pillar, grid price forecasting, is a game-changer in modern energy management. Electricity prices fluctuate throughout the day due to market demand, renewable generation, and grid constraints. Prosumers who can anticipate these fluctuations gain the ability to shift consumption to lower-cost periods, strategically charge or discharge their batteries, and even participate in energy markets.


Smart EMS: An Intelligent Orchestrator

At the apex of the energy management pyramid, the smart EMS acts as the system’s brain, balancing all the moving parts. It takes inputs from generation, consumption, and price forecasts to make real-time decisions. This includes optimizing when to store excess solar energy in the battery, when to draw from it, and when to interact with the grid.


The EMS also enables advanced grid service strategies such as demand-response schemes, where energy consumption is adjusted dynamically based on grid signals, reducing strain during peak demand periods. Moreover, it opens doors to participation in Virtual Power Plant (VPP) schemes, where the prosumer's flexibility in managing energy can be aggregated with others to provide valuable services to the grid.


The Battery: The Core of the Pyramid

At the core of every effective Energy Management System (EMS) is the Battery Energy Storage System (BESS), a critical component that ensures stability and flexibility in modern energy operations. The BESS acts as both a buffer and a power reserve, addressing the inherent variability of solar energy. It stores surplus solar power generated during peak sunlight hours for use during times of low production, such as cloudy periods or nighttime. Additionally, it smooths out fluctuations in energy supply and demand, ensuring consistent power delivery to meet user needs. In the event of a grid outage, the BESS steps in to provide backup power, enhancing energy security and reliability for prosumers.

When integrated with an intelligent EMS, the BESS becomes a tool for maximizing financial and operational benefits. By leveraging advanced automation and forecasting, prosumers can strategically reduce energy costs and unlock value through mechanisms like Virtual Power Plants (VPPs) or energy arbitrage. This includes purchasing low-cost electricity during off-peak hours, storing it, and then either consuming it or selling it back to the grid when prices are higher. Such capabilities not only empower prosumers to optimize their energy systems but also contribute to a more resilient, decentralized, and sustainable energy ecosystem.


Smarter EMS for Prosumer Solar & Storage

This integrated approach to energy management offers numerous benefits. Prosumers can achieve greater energy independence, optimize their use of renewable energy and generate additional income by participating in energy markets. More importantly, this framework supports decentralized and sustainable energy systems, where individuals and businesses actively contribute to a greener grid.
