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 controls (TGC). 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 on July
10, 2019 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 (TGC) at Jackson
Mills.

TGC Vendor

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 2019. 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.

Turbine Replacement Timeline

The TGC Replacement Project will involve 3 major subcontracts with the City; the Project
Engineer responsible for engineering design, environmental and construction permitting,
construction administration and project commissioning; the TGC vendor responsible for design,
manufacturing, delivery and installation oversight of the TGC producis; and the General
Contractor responsible for all site work, and electrical and mechanical work associated with the
installation of the TGC products. The Project Engineer, HL Turner Group, was approved in

January 2020, and they have assisted in negotiating some of the technical details contained in the
Mavel contract documents.

The timeline of this project is extremely sensitive to completing the work in low flow conditions,
generally late summer into early fall. Because of the length of time needed for proper permitting
and manufacturing of the TGC, the replacement is scheduled to take place m 2021. Upon
contract approval, Mavel will work closely with HL Turner, the Project Engineer, to finalize the
Project schedule and provide the design drawings HL Turner will need to initiate the permitting
process with Municipal, State and Federal agencies. The timeframe for manufacturing the
turbine, generator and controls is approximately 11 months, with delivery of the TGC to
correspond with completion of the site preparation work to be performed by a General
Contractor.

Attached is the scope of work Mavel Americas, Inc. will provide. After many months of analysis
the Community Development Division recommends awarding the contract for design,
manufacture, delivery and installation of the turbine, generator and controls for the Jackson Mills
Hydroelectric to Mavel Americas, Inc. of Boston, MA in the amount of $1,271,700.
