Re: Jackson Mills Turbine, Generator and Controls (TGC) Replacement

Background

The City of Nashua became the owner/operator of the Jackson Mills hydroelectric facility in
January of 2015, after the 30 year lease with the operator expired. This one megawatt facility
produces an average of 4,000,000 kwh of clean power per year which the City net meters to
maximize revenue. This facility was originally built in 1984 and as such is in need of
replacement of the turbine, generator and major controls. The project has been repaired twice
since 2015 in an attempt to keep it going until we can get started on a replacement.

Bond Authorization

In preparation for the replacement the Mayor and Board of Aldermen passed R-19-142
authorizing the issuance of bond for improvements to both Mine Falls and Jackson Mills hydro
projects. The issuance of the bond specifically included a new turbine, generator and
replacement controls (TGC) at Jackson Mills.

Turbine Replacement

Turbine technology has changed since the 1980s and the existing custom turbine cannot simply
be duplicated. In partnership with our operator Essex Power Services and sub-consultant HL
Turner Group, the TGC replacements were put out to bid in the spring of this year. In total we
received five submissions from AmJET Turbine, Mavel, NORCAN, Ossberger(Zeco) and Rickly
Propel. The team reviewed the proposals based on cost (including general construction to make a
new unit fit), reliability and generation capability/technology. The top three vendors were
narrowed down to Ossberger (Zeco), AmJET and Mavel. With these three vendors a more
detailed feasibility analysis of the exact scope of product, costs, guaranteed power and energy
estimates was completed. Through the above process one vendor, Mavel, rose to the top of the
analysis as the best solution for the Jackson Mills project.

Engineer of Record

With a TGC vendor selected, we then tured our attention to an engineering firm with the
experience and capabilities to implement the removal of the existing TGC and installation of a
suitable replacement including design, permitting, and construction administration. There are a
limited number of experienced engineering firms in New England that have expertise in hydro
facilities. Additionally, H.L Turner Group has extensive involvement with the Jackson Mills dam
and hydroelectric facility including installation of the original hydro facility and the conversion
of the dam to a hydraulic crestgate in 2012. In accordance with NRO 5-83 Professional Services

competitive bidding shall not be required for specialized services when evaluated in the context
of that NRO.

The City, in conversations with Essex Power Services, solicited HL Turner Group as the
Engineer of Record for the project. Discussions with Pennichuck who recently went out for bid
for a major dam project, support the high quality performance of HL Turner Group.

Timeline

The timeline of this project is extremely sensitive to completing the work in low flow conditions,
generally late summer into early fall. As such, part of selecting a general contractor is their
ability to deliver the installation during the summer and fall of 2020 or we risk having to
postpone the project for a full year.

Attached is the scope of work HL Turner Group will provide. After many months of analysis the
Community Development Division recommends awarding the contract for the Engineer of
Record for the Jackson Mills Hydroelectric Turbine, Generator and Controls replacement to HL
Turner Group of Concord, NH in the amount of $442,521.
