The Commonwealth of Massachusetts is seeking a qualified vendor to develop a secure, scalable data development portal dedicated to energy and environmental datasets. This centralized web-based platform will support the publication, management, and sharing of data and dashboards for use by the public, researchers, policymakers, and other stakeholders.

Key requirements for the portal include an intuitive interface with self-service capabilities, seamless integration with multiple data sources, high system accuracy, and fast performance. The solution must comply with accessibility standards and offer multiple viewing options. Core features include data descriptions, customizable search functionality, downloadable datasets in various formats (such as Excel, CSV, and JSON), and interactive tools for data visualization. The platform must support optimized backend performance, system uptime, data lineage diagrams, and the ability to add new datasets over time.

The portal should be accessible from mobile devices and enable users to display and explore data on configurable maps and dashboards. Provisions for secure and scalable data storage are essential, ensuring the management of both current and historical datasets, with clear data sources, limitations, and refresh dates provided.
