Optimize your energy and capacity markets

N-SIDE Power Matching Algorithm for power exchanges optimally matches supply and demand in closed-gate auctions. This Market-clearing solution is currently running in several markets, setting day-ahead electricity prices and transmission capacity allocation for market participants and grid operators.

Maximize welfare with integrated energy market optimization

N-SIDE Power Matching Algorithm for power exchanges is an auction optimization algorithm that can be integrated within new or existing energy market operations. It is currently in use in several markets, including India. 

The algorithm was developed by N-SIDE, building on the strong experience acquired with the implementation, maintenance, and support of EUPHEMIA, the algorithm used for the European single day-ahead market coupling. On a daily basis, EUPHEMIA matches bids and offers for about 200M€ value and calculates the day-ahead prices and cross-zonal flows for the vast majority of European countries.

N-SIDE Power Matching Algorithm matches supply and demand bids in a closed-gate fashion, considering potential congestion and other network constraints, to reach solutions that maximize social welfare. The algorithm returns market clearing prices and volumes for each time period and geographical area. It can be used for various market time frames, such as long-term, day-ahead, or close to real-time operations.

It allows market participants to use a wide range of bids to best reflect their offer or need. Similarly, the system operator can provide various types of network constraints to be considered at the market clearing stage.

The market clearing solution takes the order books (single bids, block orders, etc.), network data (topology, ATC, PTDF, losses, ramping, etc.) and market rules (pay-as-clear, tiebreak, etc.), and matches supply and demand in the most optimal way for maximum social welfare, while respecting various constraints.

The solution is able to cope with a large number of binary variables. This is done by integrating cutting-edge optimization techniques (mixed-integer linear and quadratic programming) into a robust algorithm relying on a high-quality mathematical solver, boosted with side heuristics.

Power matching outputs img


The algorithm outputs market prices, activated volumes, allocated capacities, congestion rents and other relevant metrics. This optimization can also couple multiple periods (e.g. 96 quarter-hours) and order books from multiple markets.

Production planning optimization

N-SIDE experts can help you optimize all steps of manufacturing and drug flow (e.g. quantities, timing, allocation) across the clinical supply chain, from formulation to packaging and beyond.

Adapt your manufacturing to real-time events, manage risks, and plan up to 10 years out. If you have scarce resources, a complex manufacturing network, or a large amount of products, this service delivers valuable visibility, control, and waste reduction.


Strategic manufacturing
decisions optimization

Many important decisions need to be made in R&D manufacturing/CMC. Outsourced or in-house manufacturing? Which network should I use? What’s the optimal stability plan? What’s the best way to handle scale-up to Phase 3 and the transition to commercial?

N-SIDE clinical manufacturing specialists will use our software to optimize the most important strategic decisions for your program, delivering important cost savings and waste reduction.



Change management

Transitioning to a digital, data-driven clinical supply chain requires more than technology; it demands adaptation throughout the business.

N-SIDE experts will support your change management journey, starting with a clear vision associated with measurable added value for R&D efficiency.

Keeping this purpose in mind, N-SIDE will help your teams take advantage of advanced analytics to become a truly data-driven organization.


End-to-end program optimization

By optimizing manufacturing for the entire clinical program and optimizing supply for each individual trial, we can typically free up to 50% of the initially planned quantities and accelerate time to commercialization by 2-6 months.

We accomplish this by reducing drug needs at the trial level and limiting manufacturing waste. That enables us to either cancel production lots and re-allocate the resources to new programs, or to re-invest that drug into increased sites and recruitment speed.
