Nayveli – 10 MW

Executive summary

The Nayveli, Tamil Nadu plant is a 10 MW ground-mounted utility asset in Tamil Nadu. Three GLYDE automatic robots on 10 MW (~0.30 robots/MW) with NECTYR scheduling from 2023 commissioning—compact automatic footprint on repeatable rows. Taypro implemented Fully automatic waterless cleaning under CAPEX.

Operations report roughly 1.4 million litres of water saved per year, about 375 MWh of additional clean generation, and 186 metric tons CO₂ equivalent (site-reported; validate with your SCADA).

Robotic cleaning means scheduled cycles and weather-aware holds—not flooding modules on a daily wash calendar.

Site statistics at a glance

Fleet design at 10 MW

Three GLYDE automatic robots on 10 MW (~0.30 robots/MW) with NECTYR scheduling from 2023 commissioning—compact automatic footprint on repeatable rows.

Nayveli is the ten-megawatt automatic reference in Tamil Nadu—compare Chennai semi-automatic portables and Kupti fourteen-megawatt portables for mode contrasts.

NECTYR operations and accountability

NECTYR provides fleet visibility, automated cycle scheduling, and alerts—not a plant-wide clean-now button. Supervisors review completion maps, wind and rain holds, and idle trends weekly in dust season.

Cleaning cadence: scheduled cycles and weather-aware holds

Taypro GLYDE automatic fleets do not run a naive “every module, every night” wash. Each unit is assigned to a ground-mount array with a docking station and executes scheduled waterless cycles in block-wise windows—typically post-sunset or pre-sunrise, outside peak generation—configured in NECTYR. Plant studies set how many runs occur per month; utility programmes commonly align with roughly 3–10 dry-cleaning cycles per month, often denser in peak dust season (for example 6–10) and lighter in quieter months, as described on cleaning technology and cleaning service pages.

AI- and ML-informed scheduling in NECTYR combines weather forecasts, rain probability, wind limits, and fleet telemetry. After effective rain, robots often stand down to avoid redundant passes; after dust fronts, schedules tighten so performance ratio recovers before the next revenue-critical period. Operators see the same weather context used for wind holds—overrides should be informed, not blind.

Each completed GLYDE run is a dual-pass waterless cycle on fixed tables, with dust removal quoted per completed cycle under performance methodology—not nameplate efficiency gain and not guaranteed daily coverage of the full DC footprint.

Commissioning and handover

Commissioning sequenced high-soiling blocks first, validated geometry and docking or staging, and trained technicians on waterless compliance and hold rules.

What Nayveli teaches owners at 10 MW

Nayveli is the ten-megawatt automatic reference in Tamil Nadu—compare Chennai semi-automatic portables and Kupti fourteen-megawatt portables for mode contrasts. Use the ROI calculator with conservative GWh attribution and utility operations framing.

Lenders should request block-level proof: NECTYR completion and hold logs. Pair 1.4 million litres, 375 MWh, and 186 tCO₂e on one assumption set.

Regional soiling at 10 MW

Tamil Nadu coastal-influenced dust and humidity on a ten-megawatt table. Downwind rows soften in inverter data before drive-by inspections; programmed cleaning with block proof beats episodic tanker washes.

Before Taypro, manual programmes struggled with frequency, water logistics, and auditability on 10 MW tables.

Monthly operating calendar

Jan–Feb: review brush wear and cycle plans. Mar–Jun: peak dust—scheduled density toward 6–10 cycles per month class on automatic peers where applicable; not nightly full-plant wash. Monsoon transition: stand down after effective rain. Post-monsoon: re-walk paths after civil or vegetation works.

SCADA correlation

Pair inverter trends with NECTYR timestamps. If PR stays soft after logged cleans, investigate brush wear, partial coverage, or equipment fault.

Water and finance narrative

Model 1.4 million litres avoided against tanker and wet-wash baselines. Stress-test 375 MWh at 50% and 75% attribution before sign-off.

Fleet: 3 GLYDE automatic (~0.30 robots/MW)

Three GLYDE automatic robots on 10 MW (~0.30 robots/MW) with NECTYR scheduling from 2023 commissioning—compact automatic footprint on repeatable rows.

ESG and insurer pack

Include night traffic plans, training records, and sample NECTYR weeks with water and carbon slides on consistent assumptions.

Procurement checklist

• Row repeatability map before copying robots/MW from this case study.

• Manual baseline year for water and labour.

• Block-level completion proof requirement in contracts.

• Phase commissioning on highest-soiling blocks first.

• Read cleaning technology and performance methodology.

Who should benchmark Nayveli?

Owners with 10 MW Tamil Nadu assets and fully automatic constraints—not plants copying fleet counts without maps.

How many cycles per month?

Site-specific; commonly roughly 3–10 dry cycles per month, weather permitting—not daily washing of every module.

Seasonal operating calendar

Jan–Feb: review brush wear and cycle plans; validate wind and rain hold rules in NECTYR or inspection logs. Mar–Jun: peak dust—scheduled cycle density increases on priority blocks (weather permitting), often toward the 6–10 cycles per month class for automatic fleets; not nightly coverage of every module. Monsoon transition: stand down or lighten cycles after effective rain; inspection-heavy weeks where appropriate. Post-monsoon: re-walk paths after vegetation or civil works; update block timers before the next approved cleaning window.

Technical committee closing brief for Nayveli

Attach row maps, NECTYR samples, and conservative 375 MWh / 186 tCO₂e stress tests. 1.4 million litres water avoided should use the same assumptions as generation slides.

Scheduled cycles and weather-aware holds—roughly 3–10 dry cycles per month on automatic peers, weather permitting—not daily plant-wide washing. Read cleaning technology and performance methodology.

Compare peers linked above; request layout review via contact when row maps are preliminary.

Finance workshop agenda

Validate manual baseline; agree PR normalization; review NECTYR holds and completion; align ESG water and carbon on one assumption set; budget spares and training through year five.

Operations FAQ

How are cycles scheduled?

NECTYR weather-aware block timers on automatic rows plus NYUMA weekly plans on portable zones—not a daily wash of the full plant.

What should lenders review?

Water statistics, NECTYR hold logs, training records, and GWh stress tests at 50% and 75% attribution.

Operations evidence summary

Owners should validate reported water, generation, and carbon statistics with local SCADA and tariffs; pair this 10 MW case study with performance methodology, the projects hub, and the ROI calculator. Scheduled cycles and weather-aware holds—not plant-wide daily washing—define Taypro utility programmes.

Compare Soyegaon, Chhayan, and tier-1 peers before copying robot density. Block-level proof—NECTYR exports—belongs in lender packs alongside 1.4 million litres and 375 MWh stress tests at fifty and seventy-five percent attribution.
