Seven Tips to Assist with Connecticut PURA Filings

Thoughtful preparation can help applicants avoid common pitfalls, streamline regulatory review and improve the likelihood of success.


DC

Entities appearing before the Connecticut Public Utilities Regulatory Authority (PURA) — including utilities, developers, energy service companies, municipalities and investors — face a highly structured and increasingly rigorous regulatory process. Whether initiating a docket or responding within one, outcomes depend on preparation, strategy and the strength of the evidentiary record.

Below are seven key considerations for any party participating in a PURA proceeding:

1. Understand Pura’s Policy Priorities

PURA’s decision-making can be closely aligned with Connecticut’s broader policy objectives, particularly around affordability, reliability, equity and decarbonization. Filings that clearly tie project benefits to these priorities are more likely to gain traction.

Applicants should:

  • Address ratepayer impact and cost containment.

  • Highlight system reliability, resilience and grid-modernization benefits.

  • Articulate how the project advances state climate mandates and emissions reductions.

A technically sound filing that does not connect to these policy-drivers may face increased scrutiny or limited support.

2. Make Your Case Throught the Proceeding

Success at PURA depends not only on the strength of your initial filing, but on how effectively you develop, support and refine your position throughout the proceeding.

  • Tell a consistent story from start to finish. Align your petition/filing, testimony and discovery responses — PURA will notice (and discount) shifting rationales or unexplained changes.

  • Use testimony to frame the issues early. Don’t wait to react — define the key questions, policy framing and desired outcome in your pre-filed testimony.

  • Treat discovery as advocacy, not just compliance. Clear, well-supported responses reinforce credibility and strengthen your narrative; weak or evasive answers do the opposite.

  • Address weaknesses proactively. Acknowledge and mitigate vulnerabilities (costs, alternatives, impact) before other parties raise them.

  • Use rebuttal strategically. Focus on narrowing issues, correcting the record and reinforcing your strongest arguments — not rehashing your initial case.

  • Maintain credibility at all costs. Accurate, consistent and transparent positions are often as important as the substance of the argument.

  • Keep the end decision in mind. Frame arguments in a way that is easy for PURA to adopt in a written decision (clear standards, workable conditions, defensible outcomes).

Taken together, these practices can strengthen credibility, sharpen advocacy and position your case for a more favorable and durable outcome before PURA.

3. Build a Defensible Evidentiary Record

PURA places significant weight on the evidentiary record, including technical, financial and policy support. Strong filings typically include:

  • A concise application, which does not bury the lede – clearly state what you are asking for and why.

  • Pre-filed testimony that defines the key questions and positions PURA to adopt your preferred outcome.

  • Detailed engineering analyses and clearly stated assumptions.

  • Transparent cost estimates and supporting documentation.

  • Market or comparative data to support project need or value.

Applicants should assume that intervenors, such as the Office of Consumer Counsel, and PURA staff will scrutinize both methodology and conclusions. Unsupported assertions are unlikely to carry weight.

4. Engage Stakeholders Early

Connecticut proceedings often involve active participation from utilities, state agencies, consumer advocates and industry stakeholders.

Early engagement can:

  • Surface potential objections before positions harden.

  • Identify opportunities for alignment or narrowing of disputes.

  • Facilitate settlement discussions where appropriate.

Ignoring stakeholder dynamics until after filing can result in contested proceedings, extended timelines and less predictable outcomes.

5. Be Prepared for Robust Discovery

Discovery in PURA proceedings can be extensive and detailed. Applicants should be ready to respond promptly and consistently.

Key considerations include:

  • Ensuring internal alignment across technical, regulatory and financial teams.

  • Maintaining consistency between the application, testimony and discovery responses.

  • Anticipating follow-up interrogatories on key assumptions or cost drivers.

Inconsistent or incomplete responses can undermine credibility and slow the proceeding.

6. Plan for Timing Realities

Even relatively straightforward matters at PURA can take longer than expected, particularly where contested issues arise.

Applicants should build in sufficient time for:

  • Completeness review and potential deficiency responses.

  • Discovery and supplemental filings.

  • Evidentiary hearings and briefing.

  • Deliberation and final decision.

Project timelines that assume expedited approval without accounting for these steps may face avoidable risk.

7. Expect Increased Focus on Cost Discipline

PURA continues to demonstrate a strong focus on ratepayer protection and cost reasonableness.

Filings should:

  • Clearly justify capital and operating costs.

  • Address alternatives considered, including non-wires options where applicable.

  • Demonstrate efficiency and cost-control measures.

Projects perceived as unnecessarily costly or poorly scoped may face challenges, including reductions, conditions or denial.

Key Takeaways

In summary, PURA applicants should:

  • Align project objectives with Connecticut policy priorities.

  • Continue to make their case better throughout the proceeding.

  • Develop a rigorous and well-supported evidentiary record.

  • Engage key stakeholders in advance of filing and throughout the process.

  • Prepare for detailed discovery and extended timelines.

  • Demonstrate cost discipline and ratepayer value.

Thoughtful preparation on these fronts can help applicants avoid common pitfalls, streamline regulatory review and improve the likelihood of a successful outcome.
