Analyzing scenarios, identifying use-cases, improving grid stabilization. SgurrEnergy has in-house storage specialists that provide meticulous, detailed and comprehensive solutions for all your project needs.

A sharp decline in prices of solar PV and battery energy storage technologies has inspired an unprecedented proliferation of these technologies in the energy market which is being heralded as a landmark of paradigm altering occurrence in the power generation landscape.

Demand for power consumption is witnessing a sharp rise year on year, the generation capacity too is in the need of being ramped up. Changing patterns and behavior of power consumers with adoption of new technologies in the quest to go green has caused an acute spike in power demand which has led to a steep rise in installation of peaking power plants around the globe to respond to this conundrum.

Maintaining and managing the grid is a herculean task, the challenges and predicament it brings along are quite demanding and requires comprehensive and prompt solutions. High penetration and continually growing share of variable renewable energy sources (VRES) in the energy mix has its own set of challenges leading to grid instability, frequency irregularities and other inconsistencies causing plant or grid downtime.

With battery production reaching economies of scale, and Lithium-ion chemistry becoming a favorite across the industry for its benefit-cost ratio, BES uch as, pumped-storage hydropower (PSH) or compressed air energy storage (CAES) which have a geographical constraint and need a certain character of terrain to become operational, BESS is the most efficient, relatively inexpensive and a thorough solution to meeting peak demands or provide ancillary services.

The inclusion of renewables in the energy mix has caused a change in the demand- generation profile, known as the infamous duck curve. BESS has greatly aided in subduing the ill effects of the VRES. Although, the intermittent sources of energy offer a great alternative to the fossil based power generating facilities, they have their intrinsic drawbacks which limits their capabilities to offer a round the year dispatchability, but when coupled with a BESS their true potential is unleashed offering unrivaled benefits.

Performance, stability, reliability and resilience are the key aspects of any power generation facility. Having realized the enormous and untapped potential of solar energy which has already incentivized us for a carbon-free power generation, integrating it with energy storage technologies has further secured a safer and reliable power transmission and distribution.

Owing to its simplicity in design and modular form it is easy to integrate BESS with power production facilities, as it is it is designed to be easily configurable and highly scalable. There are various configurations of coupling BESS with a Solar PV generation facility. Choosing an optimum BESS solution entails assessing various aspects of the power generation, transmission and distribution infrastructure.

Feasibility, Energy Modelling
and Analysis

SgurrEnergy’s experienced analysis team is capable of modelling storage systems in conjunction with other variable energy resources such as wind and solar

Usage of cell specific chemistry determines the overall performance and yield of a storage project; SgurrEnergy accounts in the analysis component specific performance model and chemistry in the simulation. In addition to the chemistry, battery specific loss models and thermal response is also accounted to accurately simulate storage performance

Long term storage profile for understanding the impact of life cycles on the storage capacity along with smaller simulation intervals such as 1 minute to 30 minutes accurately determines the effective utilisation of battery storage systems. This includes the modelling of battery degradation, therefore aiding in selecting the best performing storage technology

Sub-hourly yield assessments are generated in parallel with the solar and wind generation profiles, to understand the efficacy and efficiency of battery storage integration with solar/wind power plants

The analyses can be conducted for various storage applications and business models such as:

Frequency
Regulation

Ramp Rate
Control
