Electricity grids now sit at the heart of the energy transition and the drive to provide access to essential services. The large-scale integration of new uses and sources, particularly intermittent renewables, is making grids around the world harder to operate and increasing the risks of congestion, dynamic instability and power cuts. These disruptions are often compounded by ageing infrastructure and high commercial losses, which degrade the quality of service. To address these issues, power utilities must modernise their control and metering tools, optimise revenue recovery, and stabilise their grids to ensure a continuous supply and restore investor and consumer confidence. ## The challenges of the energy transition and grid management ## Our comprehensive approach to resilient, high-performing electricity grids We support our clients from initial planning through to recommissioning, taking all relevant regulatory and technical considerations into account. #### 1. Grid analysis, modelling and diagnostics Power flow, dynamic stability (DIgSILENT PowerFactory) and short-circuit studies, complemented by field audits and economic analyses, to determine the optimal sizing and siting of investments. #### 2. BESS solution sizing and engineering Sizing of energy storage systems (BESS) to increase grid flexibility, integrate renewable energy, provide ancillary services and ease congestion. #### 3. Operational performance and loss reduction Grid modernisation through diagnostics, smart meters, GIS tools and recovery plans, including performance-based financing. #### 4. Regulation and transaction support Work on cost-of-service (CoS) tariff studies, regulatory frameworks and grid codes, as well as on the transaction phases: EPC tenders, technical specifications and PPAs.  12,5 **MW / 3h** **BESS designed** for São Tomé and Príncipe, reducing outages and improving renewable energy yield 120 **actions** **developed** to improve grid performance and regulatory capacity in Senegal 2,196 **km of network optimised** under a management contract in Guinea ## Key figures ## Why choose us  **360° expertise** A synergy of engineering, economic consulting and regulatory know-how to guarantee the technical and financial viability of storage projects.  **Revenue protection** Commercial losses and billing errors are eliminated through field audits and results-based financing mechanisms.  **ROI maximisation** Return on investment for BESS assets is maximised by factoring in energy arbitrage, ancillary services and capacity mechanisms.  **Dynamic stability** Anticipating congestion risks and analysing critical scenarios to secure the integration of clean energy. ## Our flagship projects  Optimisation of low-voltage grids and BESS deployment in Senegal ### Optimisation of low-voltage grids and BESS deployment in Senegal Commissioned by the Energy Sector Regulatory Commission (CRSE) and the Senegalese national electricity company (Senelec), our team audited 40 low-voltage networks. The assignment produced a 120-measure plan, the validation of the SAIDI/SAIFI continuity indicators and the structuring of US$6.5 million in financing to strengthen the grid's operational performance.  Grid stabilisation and renewable energy integration through BESS in São Tomé and Príncipe ### Grid stabilisation and renewable energy integration through BESS in São Tomé and Príncipe To tackle the island's power cuts, we led the modernisation of the electricity system of the national operator, EMAE, integrating 45 MWp of solar generation. The project included the sizing of a 12.5 MW/3h BESS, dynamic stability studies and an overhaul of dispatching.  Improving commercial performance and grid management in Guinea ### Improving commercial performance and grid management in Guinea Under a 48-month management contract signed with Électricité de Guinée (EDG), we took charge of turning around national operations. The asset inventory carried out by our teams enabled us to create a GIS, recalibrate protection systems and deploy prepayment meters for 500,000 residents.
