Introduction

The Future Power System Architecture programme (FPSA) is a collaboration between the Energy Systems Catapult and The Institution of Engineering and Technology. It is delivered by an independent expert body having extensive technical, commercial, regulatory, digital expertise and experience. It has a strong customer perspective.

The FPSA programme has identified the functionalities that Britain’s power system will need to meet the future requirements of customers and the ambitions of Government. It has also investigated the barriers to the implementation of this functionality and developed an innovative change and governance approach, designed to deliver the new functionalities in an agile, holistic and inclusive way.

The Challenge and Opportunity

The world of energy is in a period of rapid change.  The dynamic transformation of electricity is well under way. New assets, new services, new risks and most importantly new requirements from customers are all shaping a very different set of opportunities and challenges for the sector. Decarbonisation is a primary driver of this change. But it is reinforced by the trend towards decentralised energy, the advance of digital technologies and greater customer This is creating a ‘perfect storm’ for the transformation of our power system. The challenge is to facilitate this transformation in an efficient and timely way that delivers value to customers. .

Our Scope

The FPSA programme has been focused on the Whole System (ie the traditional power system together with all the installations, appliances and devices on the customers’ side of the meter) and its touch points to the other energy vectors. Its initial task was to identify the new functionality that Britain’s power system will need to support the wider energy transformation. Subsequently, the programme has investigated the barriers to implementation and developed an innovative change and governance approach, designed to deliver the new functionalities in an agile, holistic and inclusive way. This approach could be applied to the other energy vectors to deliver a true Whole System strategy.

Our Approach

The FPSA programme has adopted a rigorous systems engineering approach to identify the new Whole System functionality that Britain’s power system needs. It has examined the existing regulatory arrangements that are designed to deliver change and concluded that they are not fit for purpose. It has proposed a new approach to change governance to catalyse thinking and accelerate governance reform.

A key aspect of the FPSA approach is that it does not dictate technical or market solutions. Rather, it assists stakeholders to engage and develop their own solutions in ways that meet their needs and are robust for the future, using principles that ensure Whole System integration.

Our Outputs

FPSA Phase 1 of the programme identified the new functionality needed by Britain’s power system. FPSA Phase 2 set out a new approach to change governance that could deliver this functionality in an efficient and timely way. FPSA Phase 3 has added detail to the Phase 2 proposals and shown how they could be applied using use cases focused on the growth of electric vehicles.
