Reinvestments

Open sourced lifetime and risk models for electric utilities

The Common Network Asset Indices Methodology (CNAIM) originated in the UK to support a regulatory structure that minimizes risk, considering the actual condition of assets considering age, loading, as well as measurements, corrosions and oil chemistry observations.

CNAIM also includes a standardized set of condition questions that cover metal fatigue, rust and signs of leakage to build an accurate estimate of the probability of failure.

The reinvestment module calculates SAIDI and SAIFI every night, using the latest information about the topology. With the module it is possible to minimize risk, minimize cost of interventions or maximize quality of service metrics e.g., SAIDI and SAIFI.

ISO Complaint

The module aligns fully with ISO 55000 standards. The ISO 55000 standards aim to set up a comprehensive management system to structure asset management within an organisation. The benefits of asset management compliant with these standards includes:

  1. Create value; assets aim to create value for the organization and its stakeholders. Management of the assets does not focus on the assets themselves, but on the value that the assets can add to the organization. Value is determined by the organization, its stakeholders in accordance with the goals of the organization.

  2. Adoption; asset management translates the organization’s goals into technical and financial decisions, plans and activities. Together sets decisions (technical, financial, and operational) on asset management, an organization able to achieve its goals.

  3. Goal achievement; asset management provides assurance that assets will meet the required target. The need for goal achievement stems from the need to lead an organization effectively. Goal fulfilment applies to assets, asset management and the associated management system.

  4. Leadership; leadership and work structures are determining factors for value creation. Leadership and arrangement at all management levels are crucial for the success of establishing, operating, and improving the management of assets in the organization. ISO55000 & ISO55001 focusses on asset management.

The low-cost approach to risk management

Our reinvestment module is fully transparent and relies on the open source CNAIM package. Read more on www.CNAIM.io.

With CNAIM.io utilities and regulators can investigate a risk-based approach to asset management without having to purchase expensive, custom build solutions.

Built-in fault analysis tools allow the lifetime parameters and input variables to be customized according to new geography and asset types. This allows the CNAIM standard to evolve according to the needs of a quickly changing power system.
